Transit at Government Center
The three main Miami-Dade Transit-operated systems (Metrobus, Metromover, and Metrorail) at Government Center station in downtown Miami. Not pictured is STS paratransit.

The Greater Miami area, composed of the three counties of Miami-Dade, Broward, and Palm Beach, also known collectively as South Florida, is home to a wide variety of public and private transportation systems. These include heavy rail mass transit (Metrorail), commuter rail (Tri-Rail), automated guideway transit (Metromover), highways, two major airports (Miami International Airport (MIA) and Fort Lauderdale – Hollywood International Airport (FLL)) and seaports (Port of Miami and Port Everglades), as well as three county-wide bus networks (Miami-Dade Metrobus, Broward County Transit (BCT), and Palm Tran), which cover the entire urbanized area of South Florida. Census and ridership data show that Miami has the highest public transportation usage of any city in Florida, as about 17% of Miamians use public transportation on a regular basis, compared to about 4% of commuters in the South Florida metropolitan area. The majority of public transportation in Miami is operated by Miami-Dade Transit (MDT), which is currently the largest transit system in Florida and was the 14th largest transit system in the United States in 2011.

South Florida is one of the most densely populated urbanized areas in the United States overall, being bound by the Atlantic Ocean to the east and the South Florida Water Management District and the Everglades to the west, with a fairly strict Urban Development Boundary (UDB). As of the 2010 US Census, South Florida is both the eighth most populous and eighth most densely populated metropolitan area in the United States. Now, with a population of over five and a half million people living in an urbanized area of only 1,116.1 sq mi (2,891 km2), it has an average population density of over 5,000 residents per square mile. According to the population as of the 2010 US Census, the 35.68 sq mi (92 km2) Miami city proper has an average population density of about 12,139 residents per square mile, with Downtown area, particularly Brickell, being the fastest growing and most dense neighborhoods.

A major problem for urban planning and effective public transit in Miami-Dade and South Florida is the fact that in terms of planning, it is one of the most sprawled out and automobile dependent metropolitan areas in the United States, with a lot of lowly contrasted medium density development spread throughout the area. For example, a very low percentage of the area's office space is located in the Central Business District (CBD) of Miami (only 13%, the lowest in the nation, in 1999). Additionally, there has been very little transit-oriented development (TOD). Subsequently, transit access between people and jobs in the city and region remains limited.


Transport in South Florida is largely dominated by roads and highways. While the region originally burgeoned because of Henry Flagler's railroad, much of it was built from the 1920s Florida land boom onward, through eras that saw the rise of the automobile, the fall of streetcars, then the general fall of public transport during the 1950s and 1960s. The 24-mile (39 km) Metrorail, located solely in Miami-Dade County and centered in Miami, is the state's only heavy rail mass transit system, and generally has low ridership per mile, per station, and even per population compared to other systems. It was planned after public outcry against an extensive highway expansion plan during the 1970s energy crisis during a time other regions such as the San Francisco Bay Area were also building heavy rail under the Carter Administration. After it was built, it was derogatorily referred to as "Metrofail" due to low ridership, cost overruns, and an inability to finish what was supposed to be a 50-mile (80 km) system. The system slowly gained ridership, but only at a rate comparable to population increases. Tri-Rail, which runs west of South Florida's urban centers, is an exceptional financial loser, even compared with other subsidized transport, and was nearly shut down during the Great Recession in 2009. There is a proposal to bring a commuter rail line to Henry Flagler's Florida East Coast Railway line that does pass through the urban centers, but is many years off and will may have to coexist with the major Brightline service by All Aboard Florida that is planned for the line.

In South Florida, there are two Florida Department of Transportation districts and three Metropolitan Planning Organizations. There are county-wide bus systems, trolley networks in smaller cities and two rail systems, one serving Miami-Dade County exclusively, the other stretching across Miami-Dade, Broward and Palm Beach counties.

Florida has no state-level income tax, but has more toll road mileage than any other state. South Florida is home to a large number of these tolled or partially tolled roads with express lanes, the latter of which can have a variable rate that can rise to over US$1 per mile during crush loads. Highway expansion through wideing projects, the addition of express lanes, and the rebuilding of interchanges has persisted into the 2010s, though traffic congestion is as bad as ever, ranking high among United States metro areas.

With a population nearing six million, Miami-Dade Transit, Broward County Transit, and Palm Tran combined carry less than half a million passengers per day, a number that works out to less than 5% of the population using transit regularly once round trips are figured. In Greater Downtown Miami, which has seen more than 100% population growth since 2000, the Metromover system carries almost half the daily riders of the Metrorail system with only about 4 miles (6.4 km) of track. Although it directly connects to the Metrorail system at two stations, nearly 80% of the ridership is through direct boardings. This mode alone would suggest at least 15% of the downtown-area population uses transit. Historically, Metromover ridership remained fairly steady from 1995 (after outer loop extensions) to 2002, when the 25 cent fair was lifted, making the system entirely free to use. After this, ridership spiked by more than 60% within two years, but it was not until 2013 that ridership doubled from 2002. In a region and state not overly inclined to public transport, this system is considered successful and a vital part of downtown life. The elimination of the fare was just a small part of a sales tax increase that was approved by two-thirds of Miami-Dade voters under the promise that major rail-based transit extensions would take place. Funds were misused and it was later admitted that the half-cent increase was known to never be nearly enough for what was promised, further souring public opinion of local transit and government.

Miami International Airport (MIA) is one of the busiest airports in the United States in terms of total passenger traffic and cargo traffic, but especially when it comes to international traffic. It is considered to be the largest economic engine in Miami-Dade County, and has a large employee base. It was connected to the Metrorail system in 2012 via the only significant extension to the system in its history, the AirportLink that created the Orange Line, which most significantly led to higher service frequency in the southern portion of the existing Green Line. The connection is made at the Miami Airport Station through the MIA Mover people mover, and the station only sees about 1,500 passengers a day, much lower than many of the system's other stations. With headways cut in half, ridership rose much more on double-lined portion of the system from Earlington Heights to Dadeland South stations than the Airport Station itself. MIA has seen record growth in the 2010s, with the addition of many major international flights and carriers, though many are connecting flights, similar to Hartsfield Jackson, with Miami being a layover not a final destination.

As the population of South Florida fluctuates similar to the rest of the state, traffic, transit ridership, and flight volumes (FTL) are all generally greater in the winter season.

Miami-Dade County contains many grade separated highways built to Interstate Highway standards. The main north–south thoroughfare for the entire tri-county area is Interstate 95. I-95 and the Palmetto Expressway, a sort of bypass freeway that serves the farther inland part of the county, are the two busiest roads in South Florida, with traffic in places exceeding 250,000 vehicles per day. Interstate 95 terminates into U.S. Route 1 just south of downtown Miami, in the Brickell neighborhood.

I-95 has three east–west spurs in the Miami area; from south to north, they are I-395 and I-195 in Miami-Dade County, as well as Interstate 595 in Broward County. I-395 is a short highway that runs east from I-95 and terminates on the MacArthur Causeway, en route to South Beach, Miami Beach; west of I-95, the same alignment is known as the Dolphin Expressway, which continues west all the way to the edge of the urban boundary at NW 137 Street just past Florida's Turnpike, while Interstate 395 crosses the MacArthur Causeway, becoming route A1A, and terminates into 5th Street in South Beach, Miami Beach. A few miles north, another east–west highway alignment exists, known as State Road 112 on the west side and as Interstate 195 east of I-95; State Route 112 terminates at the northeast corner of the airport and is also known as the Airport Expressway, while Interstate 195 goes east over the Julia Tuttle Causeway to Miami Beach. In Broward County, north of Miami, east–west Interstate 595 connects I-95 to Fort Lauderdale to the east, and to the west it is known as Alligator Alley after it meets the Sawgrass Expressway and terminates into Interstate 75, which crosses the entire state of Florida before turning north.

Many highways and roads intersect at the complex Golden Glades Interchange near North Miami Beach in Miami-Dade County.

The Dolphin, Airport, Don Shula, and Snapper Creek expressways, as well as the Gratigny Parkway all have tolls and are all managed by the Miami-Dade Expressway Authority (MDX). The Sawgrass Expressway was once managed by the Broward County Expressway Authority, but was sold to Florida's Turnpike Enterprise in 1990. The rest of the highways and the majority of major roads in Miami-Dade County, as well as the state, are operated by the Florida Department of Transportation (FDOT). The Rickenbacker Causeway is a tolled and divided highway managed by Miami-Dade County.

Termini of the controlled-access, tolled Florida State Roads (and their common names), as well as the southern extension of Florida's Turnpike, all serving Miami-Dade:

  • SR 112 (Airport Expressway): Interstate 95 to MIA
  • Homestead Extension of Florida's Turnpike (SR 821): Florida's Turnpike mainline (SR 91)/Miami Gardens to U.S. Route 1/Florida City
  • SR 826 (Palmetto Expressway): Golden Glades Interchange to U.S. Route 1/Pinecrest
  • SR 836 (Dolphin Expressway): Downtown to SW 137th Ave via MIA
  • SR 874 (Don Shula Expressway): 826/Bird Road to Homestead Extension of Florida's Turnpike/Kendall
  • SR 878 (Snapper Creek Expressway): SR 874/Kendall to U.S. Route 1/Pinecrest & South Miami
  • SR 924 (Gratigny Parkway) Miami Lakes to Opa-locka

The Florida Highway Patrol is a law enforcement agency under the Florida Department of Highway Safety and Motor Vehicles with specific jurisdiction on the state's roads and highways. Miami-Dade is included in the Troop E jurisdiction, with Broward and Palm Beach counties being among Troop L jurisdiction.

Toll roads and express lanes

See also: List of toll roads in Florida
Open road tolling structure at the western terminus of the Dolphin Expressway.

Several highways have a tolling system using SunPass and toll-by-plate open road tolling, with cash tolling being completely phased out as of 2014. Both the Dolphin and Airport expressways have had an eastbound toll for years with westbound tolls planned for as long but not implemented until November 2014. On November 15, 2014, the Miami-Dade Expressway Authority implemented their new all electronic open road tolling system on the Dolphin and Airport expressways. On the Dolphin motorists are tolled as soon as they enter the highway from any ramp, so toll evasion can no longer take place by exiting before reaching a booth, as before. The increased tolling was not well received by motorists in its first few days.

Additionally, I-95 has north and south express lanes from the I-195 interchange up to the Golden Glades Interchange. Work took place from 2011 to 2016 to extend the I-95 express lanes up to the Interstate 595 interchange near Fort Lauderdale. The price on the original express lanes varies depending on traffic, with tolls originally ranging from 25 cents up to seven dollars during rush hour or other heavy traffic. The toll range was raised to 50 cents up to US$10.50 in 2014, due partially to overuse. When the extension of the 95 express lanes to the Fort Lauderdale area opened in 2016, tolls rose even further, as was predicted by FDOT engineer Rory Santana. This has stirred controversy that the system, dubbed "Lexus lanes", is creating inequality among motorists. During high demand, tolls may range around US$20 for the approximately 22-mile (35 km) distance.

Florida's Turnpike, a north–south tolled highway that runs from Orlando to Homestead. The Homestead Extension of Florida's Turnpike (HEFT) catches the outskirts of the Miami-Dade County area, while the main section runs a more central alignment through Broward and Palm Beach counties, is tolled throughout its entire route. Despite this, there is a project to add express lanes as a long stretch in South Miami-Dade is widened from six to ten lanes in places, and from ten to possibly 14 lanes for about a mile from SW 152 Street (Coral Reef Drive) to the Don Shula Expressway, adjacent to Graceland Memorial Park. Express lanes would presumably be an up charge over the existing tolls of the HEFT, which are already higher than the mainline north of Miami-Dade.

Tolled causeways include the Venetian Causeway (NE 15th Street) to Miami Beach, the Rickenbacker Causeway connecting Interstate 95 in Brickell to Key Biscayne, and the Broad Causeway connecting North Miami with Bay Harbor Islands and Bal Harbour.

A US$1.8 billion project to add tolled reversible express lanes in the median of Interstate 595, as well as to improve flyovers and connectivity to other highways was completed in 2014. The express lanes run for about 10 miles (16 km) between the Interstate 95 interchange to the western terminus at Interstate 75 and the Sawgrass Expressway in the western fringes of Broward County.

The Florida Department of Transportation has a plan to add tolled express lanes to every grade-separated highway in Miami-Dade and possibly Broward County, with some under construction as of 2014 including on the Palmetto Expressway and Interstate 75 from the Palmetto to Interstate 595. Toll road and express lane expansions continued greatly throughout the late 2010s and into the 2020s, with many of the projects to be completed by about 2022.

Other roads

The grid throughout most of Miami-Dade County, with the exception of a few cities such as Coral Gables, is a simple axis-oriented numbered street pattern. Flagler Street forms the north–south divider and Miami Avenue forms the east–west divider between roads. Hence, all streets travel east–west and all avenues travel north–south, with the numbers increasing uniformly away from the dividers. Nearly all streets are referred to and indicated by number and all have a prefix (NW, NE, SW, SE) to determine their quadrant. Many of the busier, arterial roads, are also known by their common name, such as West 42nd Avenue, which is often referred to as LeJeune Road.

All streets and avenues in Miami-Dade County follow the "Miami grid," with a few exceptions, most notably Coral Gables, Hialeah, and Miami Beach. The grid pattern was adopted after World War I as the common naming system proved too confusing, particularly for mail carriers. One off-grid neighborhood in Miami, The Roads, is thus named because its streets run off the Miami grid in an approximately 45-degree angle, and therefore all streets are known by their number with the suffix "Road" vs Street. Another busy off-grid road is Okeechobee Road (U.S. Route 27), which travels diagonally through the urban area from the northeast corner of Miami International Airport through Hialeah. Additionally, U.S. Route 1, known better locally as South Dixie Highway, Brickell Avenue and Biscayne Boulevard, does not follow grid pattern.

The majority of surface roads in Broward and Palm Beach Counties similarly follow a grid pattern. With notable exceptions including cul-de-sacs and private roads in gated communities, which are common in South Florida.

While the Florida Department of Transportation operates and maintains most of the larger surface roads, even in incorporated areas, municipalities such as the city of Miami occasionally try to assume control over specific roads. These often include highly urban roads in the downtown area such as Brickell Avenue, where they feel the more broad scoped and highway oriented FDOT is inadequate in understanding the needs of such roads.


With a high number of waterways and Biscayne Bay separating the mainland from the coastal peninsula, there are many causeways as well as draw bridges in South Florida. Three drawbridges are located in close proximity over the Miami River between downtown Miami and Brickell; the Second Avenue Bridge, the Miami Avenue Bridge, and the Brickell Avenue Bridge. The latter can cause significant delays with the heavy traffic on Brickell Avenue.

Miami has six major causeways that span over Biscayne Bay connecting the western mainland, with the eastern barrier islands along the Atlantic Ocean. The Rickenbacker Causeway is the southernmost causeway and connects Brickell to Virginia Key and Key Biscayne. The Venetian and MacArthur causeways connect Downtown with South Beach. The Julia Tuttle Causeway connects Midtown and Miami Beach. The 79th Street Causeway connects the Upper East Side with North Beach. The northernmost causeway, the Broad Causeway, is the smallest of Miami's six causeways, and connects North Miami with Bal Harbour.

Broward and Palm Beach counties have a variety of causeways, which are generally smaller as Biscayne Bay narrows to Intracoastal Waterways to the north.

Vehicle for hire

Miami taxi fare
Fare displayed on a taxi in South Beach

Taxis are very common in Miami, especially around high tourist areas such as the airport and South Beach. Many charge an up front fee of about US$2.50 for the first 1/6-mile and 25 to 50 (usually 40) cents for each additional 1/6-mile. Waiting time is around 40 cents per minute. At this rate, a trip from the airport to South Beach costs about US$30 to US$35. Fare is almost always tracked automatically using a typical electronic toll calculator. Toll road fees are added to this and some cabs charge a US$2 fee for starting at the airport. Most companies display the rate of their taxis on the outside of the cab near the back door. All taxis in Miami-Dade must be registered and certified by the county.

As an alternative to taxis, Car2Go carsharing services were introduced to the city of Miami and some other small municipalities such as North Bay Village in July 2012. Transportation network companies (TNCs) such as Uber and Lyft have both tumultuously launched in Miami, with legal problems over whether county legislature allows these services. Miami and Miami Beach are also served by the on-demand car rental service of Zipcar.

Automobile dependency

Met 2 Miami 20110307
A parking garage constitutes nearly half the volume of this new high rise in Downtown Miami

The Miami area is known for its high level of automobile dependency and lack of public transportation, which has led to an increasing traffic problem throughout the county. Nearly 20% of household income is spent on transportation and Miami had the most decentralized office space of any metropolitan area in the United States, according to a study in 2000. Despite overwhelming support for public transportation to be funded in place of several new highways in the 1970s, Miami's Metrorail system was not functional until 1984 and as of 2014 has failed to reach the scope which was promised over 30 years ago. Ridership was very low in the early years, averaging less than 10,000 riders per day. The system was not finished, even after nearly US$1 billion in federal subsidies, meaning that approximately US$100,000 was spent for each passenger. This led to criticism from then President Ronald Reagan, who stated that it would have been a lot cheaper to buy everyone a limousine. Those supporting mass transit argued that the low ridership was due to the system being incomplete and not going where people needed it to, and noted that within a few years ridership was nearing 50,000 per day. Many of Miami and Florida's politicians have not been advocates of alternative transportation. For example, both state governors Jeb Bush and Rick Scott denied funding for an intercity high-speed rail system in Florida. Two state senators tried to force Scott to accept the funding, but the Florida Supreme Court denied the case and the funding was later directed to several other rail projects across the United States.

The half penny transit tax approved in November 2002 as part of the People's Transportation Plan was promised to fund at least the Metrorail Orange Line expansions in the short term, with a long term promise to build nearly 90 miles (145 km) of track and 50 stations for Metrorail, among other things. The plan stated that no more than five percent of tax proceeds would go to administration costs. Not only was the money used for other things, it was later revealed by the federal government that Miami-Dade Transit could not actually afford to support and operate these lines even if their construction was 100% federally funded, as MDT's revenue and ridership forecasts assumed significant and regular increases in fare while assuming no loss in ridership. This, along with a more recent federal investigation and takeover in 2011 has led to Miami-Dade Transit's perception as an accountable organization.

Therefore, the Miami metropolitan area remains highly automobile dependent, with a prominent grid system made up of many wide, dangerous roads interlaced with a few highways, most of which have tolls. Office buildings and other high-rises and semi dense communities are spread randomly throughout the area, with a lowly defined central business district and no defined edge cities, leading to many long commutes in all directions. This lack of density and transit-oriented development also helped lead to the downfall of the Metrorail Orange Line North Corridor along NW 27 Avenue. Many of the buildings in downtown Miami sit atop large parking pedestals, often over 10 stories high, or have a separate, proprietary parking garage on site, such as the 14-story Southeast Financial Center parking annex. Other than the Government Center transit hub and the Miami Tower, both built in the 80s in conjunction with the system, no buildings were built with a direct connection to the Metromover until Brickell City Centre in 2015. Despite this, nearly all the condos built in the 2000s and 2010s real estate boom were in the downtown area along the Metromover lines, leading to a doubling in ridership from 2000 to 2011, with daily average ridership now at over 30,000.

With ever increasing population and traffic congestion, highways in South Florida are constantly being widened and upgraded with things such as express lanes to ease delays. Ironically, the virtually endless expansion and reconstruction projects due to rapid growth and induced demand are part of the congestion problem. The Miami-Dade area is consistently ranked as one of the worst regions in the country for traffic problems, and was ranked as the worst east coast metropolitan area for traffic in 2010. Parts of the Dolphin and Palmetto expressways as well as I-95 and Florida's Turnpike see near gridlock conditions at rush hour on a daily basis. According to a study by the American Highway Users Alliance (AHUA) in 2015, three of the nations worst bottlenecks are in Miami-Dade on the Dolphin and Palmetto Expressways. In the 2010s, increasing traffic delays were cited as an impediment to the rebounding office market. Similar to Los Angeles traffic, Miami-Dade has a loosely defined "rush hour" that extends much longer than just 8–9 a.m. and 5–6 p.m.

Miami also consistently ranks at or near the top in terms of worst drivers and number of accidents. In a 2013 study that looked at insurance and accident reports, Miami-Dade County was ranked "first in automotive fatalities, first in pedestrian strikes, first in the obscenity-laced tirades of their fellow drivers." Subsequently, Florida consistently ranks among the most expensive states for insurance premiums.

In 2007, Miami was identified as having the rudest drivers in the United States, the second year in a row to have been cited, in a poll commissioned by automobile club AutoVantage. Miami is also consistently ranked as one of the most dangerous cities in the United States for pedestrians.

Furthermore, greater Miami sees regular high speed police pursuits; the culture and geography of Miami and Miami Beach in the 1980s were the primarily influences for the fictional Vice City featured in the controversial Grand Theft Auto video game series. Indeed, the rate of motor vehicle theft in South Florida is well above the national average, with many cars ending up overseas.


Miamis (lack of) Transit Oriented Planning (6973342309)
A large parking garage run by the Miami Parking Authority in the Government Center area of downtown Miami.

As with many large cities, parking in the Miami area can be expensive and scarce. Nearly all of the public parking in the county is metered, or charged by a daily flat rate, common with parking garages. Nearly all single parking meters in the region have been removed and replaced with master meters that accept both cash and credit card. The Miami Parking Authority operates 11 garages, 86 surface lots, and over 9,100 public parking spaces within the approximately 35 sq mi (91 km2) city of Miami; adding to over 30,000 parking spaces in total. They enforce the streetside and surface lot parking meters and issue parking citations for violations. Due to high demand, a system of congestion pricing similar to highways has been considered for parking facilities in the downtown area.

Free parking at businesses is often strictly enforced to patrons, with clearly placed tow warning signs for abusing the space to go to other places or for parking for an excessive length of time, especially in highly trafficked areas such as South Beach. Many businesses have no free parking available, or do for only limited amounts of time. Even suburban plazas and big box stores often have parking security to ensure both patron safety and designated use of parking. In many suburban residential areas, people do not have their own private garages as properties are small due to high land values. A parking pass even for residents of a high rise residential building often costs an additional fee over the rent or association dues.

South Florida began its forays into and robotic parking in the 2000s, though the New World Tower, built in 1965, has a mechanical parking garage. Two of these garages have been high-profile failures, even going as far as destroying cars and shutting down, leading to lawsuits and bankruptcies.

Underground parking

Unlike most other metropolises, underground development, including basements and below grade parking, is very rare in South Florida, even in city centres, due to the low elevation above sea level. Due to the porous geography, the inland water table is often similar to the sea level. Downtown Dadeland, built in 2005 in Dadeland, has two levels of underground parking over 7.5 acres (3.0 hectares), as does the 9-acre (3.6-hectare) Brickell City Centre, which completed major construction in 2016. Into the 21st century, there was more pressure for underground parking due to zoning codes such as Miami 21, which require above ground garages to be lined with retail and avoid blank walls, aesthetics, pedestrian access, economics, and traffic control, among other things. Despite significantly higher engineering and construction costs, garages with 1.5 or more below grade levels are becoming more common for these reasons. The 2,600 sub-grade car park for Brickell City Centre covers 7 acres (2.8 hectares), and required installation of watertight slurry walls from the site elevation of 7 feet (2.1 m) NGVD to around -20 feet (6.1 m). Jade Signature in Sunny Isles Beach was built in 2014 with three levels of underground parking reaching up to 60 feet (18 m) below sea level right on the Atlantic coastline on barrier island.

South Florida is served by three international airports; Miami International Airport, Fort Lauderdale–Hollywood International Airport, and Palm Beach International Airport, as well as several smaller, regional airports, including Kendall-Tamiami Executive Airport and Opa-Locka Executive Airport.

Miami International Airport

Miami International Airport aerial 2007
Miami International Airport served over 40 million people in 2013 and is the world's 10th-largest cargo airport.

Miami International Airport serves as the primary international airport of the Greater Miami Area. One of the busiest international airports in the world, Miami International Airport serves over 40 million passengers per year, with a steady trend of growth. As of December 2014, MIA is the only airport in the nation to offer flights from 100 carriers. That month also saw the return of the Eastern Air Lines trademark to Miami (via "New Eastern Air Lines").

Identifiable locally, as well as by several worldwide authorities, as MIA or KMIA, the airport is a major hub and the single largest international gateway for American Airlines, which the world's largest passenger air carrier since its merger with US Airways in 2013. Miami International is the busiest airport in Florida, and is the United States' second-largest international port of entry for foreign air passengers as of 2013, behind New York's John F. Kennedy International Airport; it is also among the largest such gateways in the world. The airport's extensive international route network includes non-stop flights to over seventy international cities in North and South America, Europe, Asia, and the Middle East.

The airport is served by taxis, several Metrobus routes, including the dedicated Airport Express, as well as several shuttle bus services available 24 hours a day. It also has a large rental car center and parking garage, known as the Miami Intermodal Center, and a rail station for Amtrak and Tri-Rail, known as Miami Central Station; both of these centers are being completely rebuilt and since 2012 are served by MIA Mover and Metrorail's AirportLink.

Two smaller, regional airports in Miami-Dade County are the Kendall-Tamiami Executive Airport and the Opa-locka Executive Airport.

Surface transportation infrastructure

Miami Intermodal Center
Rendering of the Miami Intermodal Center, located offsite from the airport and connected via MIA Mover, that centralizes various modes of transportation for airport users.

The MIA Mover is a free, automated people mover connecting the Central Terminal of Miami International Airport to the new Miami Central Station and Miami Intermodal Center, the former of which is still under construction. MIA Mover opened on September 9, 2011 and is 1.27 miles (2 km) long, running on an elevated track. MIA Mover has a top speed of about 40 miles per hour (64 km/h) and the capacity to move more than 3,000 people per hour.

The AirportLink connects the Metrorail system to Miami Central Station and the intermodal center. It is also the only completed phase of the MDT Orange Line. It connects the phase-built Miami Central Station to the Metrorail mainline at the Earlington Heights station. It consists of a 2.4-mile (4 km) elevated line with a construction cost of about US$500 million that opened in the summer of 2012.

Miami Central Station is a major new transit hub that, along with the new Miami Intermodal Center, will connect and centralize all the major forms of surface transportation to and from Miami International Airport. MIA Mover, Metrorail's AirportLink, Amtrak, Tri-Rail, Metrobus, the rental car center, and personal vehicles will all come together there. Phase I for Metrobus, MIA Mover, AirportLink and automobiles was completed in 2012, while Phase II for Amtrak and Tri-Rail is scheduled to be completed in early 2015, with a delay of over one year as of 2014. Miami Central Station will also serve as a connection point between walking and bicycling, in addition to the aforementioned modes of transportation.

Fort Lauderdale–Hollywood International Airport

Located just to the north, in Broward County, is another large airport, Fort Lauderdale–Hollywood International Airport (FLL). FLL is connected to the Tri-Rail commuter rail system via timed shuttle bus. The airport's connections to US 1 and Interstate 595 were undergoing renovations as of the 2010s, with a major project to extend one of the airport's runway ongoing as of 2014. The runway extension is a US$791 million project that required building a tunnel and adding fill over US 1 and the Florida East Coast Railway line.

Palm Beach International Airport

Palm Beach International Airport (PBI) is a public airport located approximately 3 miles (5 km) west of Palm Beach, Florida, in West Palm Beach, Florida. It primarily serves Palm Beach County. The airport is operated and maintained by Palm Beach County Department of Airports, which also manages three regional airports in the county. Road access to the airport is available directly from I-95, Southern Boulevard, and Congress Avenue. The airport is bordered to the west by Military Trail.


The entire length of the South Florida metropolitan area is situated along the Atlantic Ocean. PortMiami in Miami-Dade and Port Everglades in Broward County are South Florida's two major seaports, while Port of Palm Beach is a smaller port located in Palm Beach County.


Miami's port as seen from Miami Beach in December 2007, with seven cruise ships docked.

PortMiami is one of the busiest cruise ship ports in the world, with annual passenger traffic growing to about five million by 2014. as well as a major cargo port. Located on an island adjacent to downtown Miami, it was for some time only accessible by automobile via a six-lane bridge known as the Port Boulevard causeway, which terminates on the city streets of downtown, or by rail. Rail service was disrupted by bridge damage that occurred during Hurricane Wilma in 2005. The damaged line, part of the Florida East Coast Railway, was repaired by 2014 renewing freight train access to the port. Along with Florida East Coast Railway's All Aboard Florida plan, this also increases the possibility of commuter rail service to the port. This also created some train traffic through Downtown Miami for the first time in nearly a decade. Additionally, to give the port direct interstate access and to help relieve downtown traffic, the $1 billion Port Miami Tunnel project to connect the port to Interstate 395 on Watson Island was completed in August 2014.

Port Everglades

Port Everglades, located in Fort Lauderdale in Broward County, is another major seaport that is about equally busy as Port of Miami in terms of cruise and cargo traffic. It is home to the two largest cruise ships in the world, Oasis of the Seas and Allure of the Seas. As with PortMiami, Port Everglades has intermittently given statistics which prove it to be the busiest cruise port in the world.


In addition to the ports, South Florida has many marinas and navigable waterways for both public and privately owned boats and yachts. The Miami River, which passes directly through the downtown Miami area, is publicly accessible and leads to inland marinas and cargo facilities. Fort Lauderdale has over 165 miles (266 km) of inland canals, owing it the nickname "Venice of America". Miami Beach has a long, inland canal system as well. Biscayne Bay is also popular sport and recreation such as fishing, sailing, and kayaking. There are also several recreational water taxis that gives sightseeing tours along the coast, such as the Miami Water Taxi, and the Fort Lauderdale-Hollywood Water Taxi.

Public transportation

Miami Metro Map 2017
A schematic map of rail transit in South Florida, from Amtrak and Brightline (2017) intercity service down to the Metromover and MIA Mover automated people movers. The red line is a light rail-style bus rapid transit line that forms an important feeder to Metrorail.

Metrorail, Metrobus, and Metromover, all operated by Miami-Dade Transit, comprise the majority of public transportation options in Miami-Dade County. Miami-Dade Transit also runs the Paratransit division's Special Transportation Service. The only significant public transportation systems currently offered in Broward County and Palm Beach County are standard bus systems, run by Broward County Transit and Palm Tran, respectively. South Florida's tri-county commuter rail system, Tri-Rail, is operated by the South Florida Regional Transportation Authority (SFRTA). There are also several localized public bus systems, such as the South Beach Local and the Coral Gables trolley.

The elongated and sprawled layout of the South Florida metropolitan area complicates the process of designing practical mass transit systems that serve the entire region, in contrast to more circular shaped metro areas where a hub-and-spoke system can efficiently route passengers or automobiles to their destination. Miami's existing Green Line and proposed Orange Line would only form the spokes, which could only emanate towards the west due to Miami's coastal location. A line towards the coast to the east, known as Baylink, has been long proposed but at high cost and being met with opposition. The entire urbanized South Florida metropolitan area, being about 110 miles (177 km) long but no more than 20 miles (32 km) wide in any part, as well as covering three counties, complicates the creation of a unified transit system. Additionally, Miami is a relatively young city that saw much of its growth during the automobile age, and continues to be very car oriented. South Florida ranked fourth in the nation in a 2000 study of metro areas for percentage of household income spent on transportation, with an average of 19%. Many of the downtown high rises have their own very large, above ground parking garages, which form the base of the towers. As of the 2000 census, it was the eighth most densely populated metropolitan area in the United States, with the city of Miami growing at about a 10% growth rate. Of large municipalities in the region, the city of Miami has the highest percentage of residents using public transportation regularly, at about 17%. Though the general trend for public transit in South Florida is for gradual growth in ridership numbers, percentages are offset as the majority of the region has seen steady increases in population over time. At a 4% commuter share, South Florida ties the Gainesville, Florida metropolitan area for the highest ratio of public transport usage in Florida.

The University of Miami is the only major institution of higher education with direct rapid transit access, via Metrorail's University Station, while the Wolfson Campus of Miami-Dade College, located in Downtown Miami, is transected by the Metromover loops.

A 2014 survey of 3,917 people in Miami-Dade County found that their highest priority was on-time performance, eclipsing by a narrow margin more frequent service and transit expansions to new areas.

As far as safety, a county report documenting incidents between December 2007 and August 2009 indicated that Metrorail had the highest amount of reported crimes with 1.5 per 100,000 riders, with battery being the main offense on both Metrorail and Metromover, while vandalism was number one for Metrobus.

From 2010 to 2015, Metrorail ridership greatly outpaced population growth, increasing by about 25%. Specifically, from 2014 to 2015, Metrorail and Metromover ridership remained fairly steady while Metrobus ridership continued to decline amid record low oil and gasoline prices that year. Despite this, there are more investments and expansions being explored for bus service than rail service, including new bus-rapid transit (BRT) and the covering of unprotected stations. By summer 2015, Metrobus daily ridership was around 210,000, nearly a 25% drop from previous records of over a quarter million. Through 2016 Metrobus ridership continued to fall sharply, while Metrorail ridership fell somewhat, and even Metromover had some slight declines.

Miami-Dade Transit

Miami-Dade Transit runs the majority of public transport in Miami-Dade County including the four major systems of Metrorail, Metromover, Metrobus, and STS paratransit. In 2011, they were nearly shut down by the federal government due to audits that revealed extensive corruption. This came during a low economic time when service cuts were already in place and threatened even greater cuts.


Train in Government Center, Miami
Metrorail trainset entering Government Center station in Downtown Miami.

Metrorail is Florida's only heavy rail rapid transit system, comprising two lines. The original, 22.4-mile (36 km) line, known as the Green Line, with 22 stations, starts at Okeechobee Station in northwest Hialeah, travels generally southeast to the CBD and Brickell, then travels generally southwest to Kendall over a historic, formerly Florida East Coast Railway, alignment. It has been in operation since 1984. In the 1970s, there was a plan to fund several more highways in South Florida, but it was decided that a mass transit option was more desirable. It was intended that the existing line would only be the beginning of the system, many more lines were planned. However, due to budget shortfalls and less than anticipated ridership, none other than the 2.4-mile (4 km) AirportLink have been realized, which, opened in 2012, connects Miami Central Station with the Green Line and merges with the latter south to Kendall.

Standard fare for both Metrorail and Metrobus was raised from $2.00 to $2.25 on October 1, 2013, for the first time since 2008 when fares were raised from $1.50, cited as being due to increasing operational expenses.

On July 16, 2008, Miami-Dade Transit announced that it would be replacing all fare collection methods with the EASY Card system by late 2009. The system replaces the old cash-/token-based system with one that automatically deducts fares at Metrorail fare gates from a reloadable card. The final station to start fare gate installation was Government Center in August 2009. Since the system launch on October 1, 2009, all passengers utilizing Metrorail must use either an EASY Card or EASY Ticket to enter stations.

Metrorail runs from 5 a.m. until midnight, seven days a week. Where the line is double, trains arrive every five minutes during weekday rush hours, every 7 and 1/2 minutes during off-peak hours, and every 15 minutes after 7:30 pm until closing at midnight. Weekend service runs every 15 minutes for the entire day. For a brief period from 2003 to April 2004, there was 24-hour service; between midnight and 5 am, trains arrived every 60 minutes. 16 of the 23 stations have dedicated, MDT-operated parking facilities, consisting of either a garage or a surface lot, with a charge that was raised from $4.00 to $4.50 during the 2013 fare hike. The stops that don't offer public parking are Tri-Rail and the five downtown-area stations, Civic Center, Culmer, Historic Overton/Lyric Theater, Government Center, and Brickell. However, there are multiple parking garages available in the vicinity of these stops.

Construction on the first segment of the Orange Line, Metrorail's AirportLink, began in June 2009; service to Miami International Airport was scheduled to begin in spring 2012, and after a slight delay service commenced in summer 2012.

The Miami-Dade County government is working with the Citizens Independent Transportation Trust oversight committee to receive money from the half-penny surtax approved by voters in 2002 in order to purchase new Metrorail cars, due to begin construction in late 2015. The 136 Metrorail vehicles will be built in Miami-Dade County at a recently constructed facility by AnsaldoBreda. Full roll out is expected by the year 2018.


Metromover is a free, automated people mover (automated guideway transit) system, similar to an elevated light rail, that operates on three loops totaling 4.4 miles (7 km) of elevated track and 21 stations in the Central Business District, "Omni", and Brickell. The main Inner Loop opened in 1986, and the Omni (north) and Brickell (south) extensions opened in 1994. The Metromover gained popularity significantly when the 25-cent fare was lifted in 2002. Since then it has been free to ride. Metromover is used heavily by those who live, work, or attend events in downtown, with ridership doubling from 2002 to 2014, as well as by tourists staying in downtown to get to attractions or just to get a free tour of the downtown cityscape. It is also used by those who commute into the city using Metrorail and Tri-Rail. Metrorail and Metromover are connected at the Government Center and Brickell stations, and even by construction workers commuting to downtown-area projects. Tri-Rail and Metrorail are connected at the Tri-Rail and Metrorail transfer station. Metromover headways vary from about two to five minutes depending on loop and overlap.

The Metromover currently operates 21 stations, and combined with the Metrorail, the entire metro system operates 45 stations. Metromover stations are located at approximately every two blocks in the Greater Downtown area, where Metrorail stations are located at about a mile apart along its line.

Until 2015, all stations except for Knight Center station located in the bottom of the Miami Tower and Government Center station located at the bottom of the Stephen P. Clark Government Center, both built in conjunction with the system in the 1980s, were stand alone units with no direct integration with other developments. In 2015, the first phase of the very large Brickell City Centre project included a renovation of the Eighth Street station that included a direct connection. Miami Worldcenter, which is being developed piecemeal, may incorporate two Metromover stations. In 2011, the proposed Resorts World Miami mixed-use casino, planned near the Omni area north of downtown, had plans to modify the Metromover line where it passed the demolished Miami Herald building, as well as building a new station into its development. The project stalled when a gambling bill did not pass the state legislature. Various other high-rise projects have also proposed a Metromover integration. One is the original design for Brickell Flatiron, which would be built over the track with a hole for the line to pass through it. Another is the long-proposed One Bayfront Plaza skyscraper, whose original, as well as its latest known designs are planned to have a pedestrian bridge connecting it to the Bayfront Park station. As far as expansion, an extension to the Port of Miami and then to South Beach has been considered among others, but none have yet made it beyond the planning and impact study stages As of 2015.


The Metrobus network provides bus service throughout Miami-Dade County 365 days a year. It consists of more than 100 routes and about 817 buses and 9000 stops, which connect most points in the county and part of southern Broward County as well, to connect with the Broward County Transit bus system. Standard fare is US$2.25. Seven of these routes operate around the clock: Routes 3, 11, 27, 38, 77, L (No 24-hour Hialeah service) and S. Routes 246 Night Owl and Route 500 Midnight Owl operate from 12am to 5am, with the 500 route replacing overnight Metrorail service. Most other routes operate from 5 AM to 11 PM. All Metrobuses are wheelchair accessible, in compliance with the Americans with Disabilities Act of 1990.

South Miami-Dade Busway
Busway level crossing
The Busway has no grade separation, therefore there are several at-grade crossings with arterial roads.

The South Miami-Dade Busway (originally the South Dade Busway) is a bus rapid transit system that began operating on February 3, 1997 and was extended in April 2005. The final 6.5-mile (10.5 km) segment of the Busway extension to Florida City opened on Sunday, December 16, 2007. The Busway features 28 stops, all of which have been converted to light rail style stations, with a total of 56 shelters. A multi-use path known as the South Dade Rail Trail stretches the length of the Busway, connecting with the MetroPath at Dadeland South station.

The Busway has been the site of many accidents at the unique intersections where arterial roads meet the virtually adjacent South Dixie Highway.

Broward County Transit

Broward County Transit (BCT) is the public transit authority in Broward County, operating a county-wide bus system covering over 400 square miles (1,036 km2) of the greater Fort Lauderdale area. It is the second largest transit system in Florida (after Miami-Dade Transit). It currently operates the only public bus system in Broward County. Besides serving Broward County, it also serves portions of Palm Beach County and Miami-Dade County where the systems share transit hubs such as Aventura Mall in Miami-Dade County.

Palm Tran

Palm Tran is a bus system run by the Palm Beach County Government, serving Palm Beach County. Standard (Adult) one-way fare is US$1.50 (people eligible for the reduced fare such as students and senior citizens pay US$0.75). For US$3.55 an unlimited all-day pass (US$2.25 for reduced fare). There are no free transfers except to Tri-Rail or Broward County Transit. Daily and 31-day unlimited ride passes are also available for purchase. There are 31-day unlimited passes that are available reduced or regular costing US$55 and US$40 respectively. All Palm Tran buses have bicycle racks on the front, capable of holding two bikes.

Other buses and trolleys

Miami Trolley

South Beach operates its own local bus system known as the South Beach Local. The fare is only 25 cents. Streetcar style trolley-replica buses have been implemented in over a dozen cities in Miami-Dade and Broward Counties, such as downtown Miami, Coral Gables, and Hollywood. Since it began operation in 2003, the free Coral Gables Trolley (bus) has moved over four million commuters around downtown Coral Gables with over 5,000 riders per day, freeing up 750 local parking spaces and reducing car trips by 20% along its route. The city of Hollywood operates a trolley route serving its downtown area and Hollywood Beach. In April 2012, Miami initiated its own trolley system with loops around downtown similar to the Metromover as well as to the new Marlins Park and Civic Center. The Miami Trolley expanded to many routes over the next few years. Educational institutions such as University of Miami (Hurry 'Cane Shuttle) and Florida International University (CATS Shuttle) operate free shuttle-bus services on and around their campuses. In addition, FIU offers a Golden Panthers Express shuttle between their main campus and the Biscayne Bay Campus.

A 2011 survey of the largest cities in the United States by determined the city of Miami to be ranked eighth in terms of walkability, with an overall walkscore of 73, though Miami provides a case study for the well-known fallibility of WalkScore for not accounting for safety and other factors. The ranking is based on proximity of restaurants, food, transit stops, and entertainment, among other things.

Transit-oriented development (TOD)

Dadeland "edge city" from busway
Though not incorporated, Dadeland has taken on the characteristics of an edge city, located about 10 miles (16 km) outside of downtown Miami. It is located at the southern terminus of the Metrorail where it meets the northern terminus of the South Miami-Dade Busway.

More priority has recently been given to transit-oriented development, with several housing and mixed-use projects being given special incentives and reduced parking requirements for building along transit lines. Examples include MDT's "transit villages". Two recently built transit-oriented developments are located at Brownsville and Santa Clara, the two least used stations in the system. The still under development Brownsville Transit Village will have 467 affordable housing units and ground level retail between five midrises on a 5.8 acre plot located immediately next to Brownsville station, which is currently the second least used Metrorail stations, average under 900 riders per weekday as of February 2011. Santa Clara Apartments I and II were opened in 2011 and are located at Santa Clara, the least used station, averaging under 800 riders per day as of February 2011. In February 2014, ridership at these stations had increased by over 20%. In 2015, plans for a Miami MLS stadium as well as a possible joint University of Miami Football stadium cited a necessity to be in Miami's urban core with a transit-oriented location.

Historically, several buildings were built in conjunction with the Metromover and Metrorail systems in the 1980s. Both systems connect on the north side of Stephen P. Clark Government Center. The Knight Center Metromover station is built into the Miami Tower (formerly Bank of America Building); it is connected via pedestrian tunnel to the James L Knight Center under Downtown Distributor overpasses. Another private development, the ambitious Omni International Mall, colloquially known as the Omni, is connected to the Adrienne Arsht Center station (formerly Omni station), by a pedestrian bridge that was closed when the majority of the mall closed. Outside of the downtown area, the highly dense suburb of unincorporated Kendall in South Dade has been built up significantly around the busy Metrorail stations of Dadeland North and Dadeland South, both of which opened in 1984, in an area known as Dadeland. This area is an officially recognized transit-oriented development by the Federal Transit Administration (FTA)-sponsored Transit Cooperative Research Program (TCRP). Both stations consistently have over 6,000 weekday passengers as of the mid 2010s, and they form the southern terminus of the current Metrorail line.

The downtown core and Brickell neighborhoods, with their dense zoning allowances, have incidentally taken on characteristics of transit-oriented neighborhoods. However, ridership increases were generally less than what is found in areas of other cities with similar densities, according to a Transportation Cooperative Research Program study from 2004 regarding transit-oriented development. One reason given was a lack of pedistrian-friendly urban fabric, such as safe street crossings and retail at transit stations, a phenomenon known as "transit-adjacent development". However, from 2004 to 2014, along with two real estate booms, ridership roughly doubled for both the Metrorail and Metromover components of Brickell station.

Metromover TOD

The Loft 2 condominium was allowed an exemption to parking requirements due to transit access.

During the large condominium real estate boom of the 2000s, nearly 50 new condominium buildings were constructed in the greater downtown area, which along with fare elimination, correlated with a doubling in Metromover ridership throughout the decade. The mid 2010s is seeing another large development boom As of 2015. Two very large projects are incorporating Metromover stations for direct access. Brickell City Centre closed the Eighth Street Station in 2014 to renovate and incorporate it into their project; Miami Worldcenter may incorporate both the Freedom Tower and Park West stations, in addition to a possible connection to All Aboard Florida's MiamiCentral station. This dense downtown development cannot be considered exclusive transit-oriented development, however, as many locations throughout the region have many high-rise and other large buildings without permanent transit infrastructure. It is more a reflection of zoning allowance; the current Miami 21 zoning code in the city of Miami lends itself to larger development, with densities up to 1,000 units per acre, and taller buildings downtown or in transit corridors, though it also sets strict and controversial parking space minimums. In addition, public transit is not considered a priority to the many high-income condo buyers, who often seek ample parking; despite this, proximity to transit if often included in the marketing of these towers. In contrast to traditional transit-oriented development, much of the real estate is a far cry from affordable housing geared toward lower and middle income residents. Real estate developers are generally required to pay high impact fees for these large buildings, the profits of which are intended to go to public infrastructure such as schools and transportation. The City of Miami impact fees ordinance was amended in 2005 due to the high amount of development at that time.

On the other hand, the "Downtown Kendall Urban Center District ordinance" from 1998 that allowed the area of unincorporated Kendall known as Dadeland to grow into a de facto edge city was in part due to its location adjacent to the inter-built Dadeland South Metrorail station and Datran Center. The Datran Center was built as a joint development between its private developer and Miami-Dade Transit. The Loft/The Loft 2 and Centro Lofts are two relatively large buildings that were allowed exemptions to parking requirements due to copious transit access. The Loft 2 is built directly over the First Street Metromover station while Centro Lofts is surrounded by the Metromover's downtown loop in addition to having an arrangement with the local Car2Go service. Due to the urban density, high-rises, cultural institutions, and access to various transit services, Downtown and Brickell are often compared to New York City, specifically Manhattan, despite being much smaller.

Future proposals and extensions

Dadeland South station
New system maps showing the Orange Line, which opened in 2012.

Many transportation systems, including highways, have been proposed, especially in Miami-Dade County, which were subsequently cancelled, often due to financial issues. During the 1970s, the time when the "Decade of Progress" local bond was approved, residents of the Miami-Dade County voted 2-to-1 for a transportation plan that cancelled highways in favor of public transit planning and funding. Heavy rail (Metrorail) expansion is estimated to have a construction cost of about $100–200 million per mile. Planned toll roads and express lane expansions, together with highway widening, continued greatly from the late 2010s into at least the early 2020s.

MDT Orange Line (Metrorail)

See also: Orange Line (MDT)

The Orange Line was a major proposal for three new Metrorail lines. One north to the Broward–Miami-Dade county line via 27th Ave, an east–west extension to Florida International University, and a link to Miami International Airport. Only one has been built, the short connector to the airport from the Earlington Heights station, known as the AirportLink, which was completed in 2012. The other two have been permanently cancelled, primarily due to political corruption, namely the misuse of the half-penny tax passed in 2002 and false ridership and revenue forecasts by MDT.

Although the only physical Metrorail addition forming the Orange Line is the single station 2.4-mile spur to the airport, the entire line from the airport to Dadeland South has been rebranded as the Orange Line, in addition to being the Green Line. This is because trains that will run to the airport will go all the way to Dadeland South, along with Green Line trains.

FEC Tri-Rail alignment "Coastal Link"

The "Coastal Link" is a long-proposed project to move or expand Tri-Rail service to the more easterly aligned Florida East Coast Railway freight line. This would bring it closer to people and boost its ridership to up to 59,000 passengers a day, according to a three-year study by the Florida Department of Transportation, as well as bring it straight into Downtown Miami, terminating near the Government Center transit hub. Additionally, service could be extended northward to Jupiter, located in the extreme northeast corner of Palm Beach County. The east–west crossover between the lines would allow both to go to Miami International Airport or downtown Miami, and a second spur to the port, which already exists, might also be used for Tri-Rail service. The FEC line would have to be vastly upgraded to make this move possible, as much of it was only a single line at this time, where Tri-Rail requires two. Additionally, all new stations would have to be built. It is uncertain whether or not Tri-Rail would continue to operate its current line at the same time. The expansion proposal by Tri-Rail's current operator, the SFRTA, would have trains running on both lines, while the other proposal by the Florida Department of Transportation might only operate on the FEC line. The state is looking to possibly privatize operations of Tri-Rail, with the FECR likely to operate any future passenger rail on its line, while the current line may be operated by other private entities. An east–west connection between the lines would give South Florida a much more complete commuter rail system. Much of the FEC line was single tracked, and would need to be at least double tracked to handle freight, passenger, and possible Amtrak service. For this reason, many of the preliminary plans called for the project to be cut into phases, such as an initial improvement of the line between Miami and Fort Lauderdale. Pending local and state funding, as well as a possible Federal Railroad Administration grant, service was anticipated to begin on at least part of the FEC line as early as 2015. On October 28, 2011, the SFRTA Governing Board approved a plan to run Tri-Rail local and express service on the FEC line to Downtown Miami by 2015. The plan then went to the tri-county Metropolitan Planning Organization (MPO)'s boards for approval. The plan was being fast-tracked in phases to provide service on the FEC portion from Downtown Fort Lauderdale and Downtown Miami's Government Center Station as soon as 2014. These plans largely stagnated due to lack of funding and uncertainty in dealing with Florida East Coast Railway.

Plans for a Tri-Rail "Coastal Link" resurfaced with the construction of FEC's All Aboard Florida intercity higher-speed rail system in 2014. One plan for early action called for the possibility of rerouting trains on the CSX line over a spur in northern Miami-Dade County to the FEC line where trains would run from the Midtown area to the lines termination at All Aboard Florida's MiamiCentral station in downtown Miami. Another plan calls for an initial six stations between downtown Miami and Aventura. Although the All Aboard Florida project includes double tracking the entire line in South Florida, the Coastal Link would require the construction of its own stations between All Aboard Florida's three stations, as well as the possible addition of a third track, at a cost estimated between US$720 and US$800 million in 2014.


BayLink is a long proposed streetcar, light rail, or Metrorail extension that would connect Downtown Miami to South Beach via the MacArthur Causeway, with the light rail or streetcar options potentially having loops at both ends. Originally proposed as a light rail line such as a monorail, Miami Beach city officials opposed this in favor of something less intrusive, such as a streetcar. They also cited concerns of unwanted downtown residents detrimenting the South Beach image. Additionally, the unused parts of the bases of the MacArthur Causeway bridge pilings that were to be used to support the line have been used for the widening of the causeway for the construction of the Port Miami Tunnel. Officials still thought it was feasible, as a light rail streetcar, and in 2014 were considering the possibility of a public-private partnership to help fund it.

2016: SMART plan

In 2016, a new plan was introduced, known as the Strategic Miami Area Rapid Transit (SMART) expansion plan. It outlined six corridors in need of premium transit lines, NW 27th Avenue North Corridor, FEC line Coastal Link, an east-west line likely following the Dolphin Expressway, South Dade Busway conversion, Kendall Corridor down Kendall Drive (SW 88 Street), and BayLink (Beach Corridor). The Beach Corridor line might also connect Midtown and downtown Miami. The lines would most likely use at-grade heavy rail at best, but may be bus-rapid transit, light rail, or Metromover in the case of BayLink. The price would likely be at least $70 billion for all 70 miles (110 km). In early 2017, funding for studies was moved forward, with some controversy.

Downtown streetcars

Several street cars, jitneys, and other local bus routes have been proposed in Miami for the Downtown/Brickell/CBD/Omni area. A notable example is a proposed streetcar line down Biscayne Boulevard from Downtown to Omni. Miami had streetcars since 1909. By the 1920s, downtown had an extensive streetcar system, including an express line from Miami to Coral Gables that exceeded 70 miles per hour (113 km/h). However, the 1926 Miami Hurricane damaged the system and as time passed they were all removed.

Fort Lauderdale had plans in 2011 for a 2.7 mi (4 km) downtown light rail streetcar system to be called The Wave Streetcar. After delays the project received final approval in 2013 and, funded with the help of federal subsidies, construction was to begin in 2014. The project then met further difficulties including risk of losing the federal money, and construction was pushed back to 2017-2020.

Transit to PortMiami

FEC line track repair to Port of Miami
The southern end of the FEC rail line was renovated in 2011 for freight service to return to the seaport.

In mid-2011, a US$120,000 study was proposed to analyze the feasibility and impact of building a Metromover extension to the PortMiami. This would create a somewhat direct elevated transit link from Miami International Airport to the seaport, Miami-Dade County's two largest economic generators. Multiple transfers would be required, however, as a trip from the airport to the seaport would start with the MIA Mover, then Metrorail's AirportLink, then the Metromover port line. In 2014, A Metromover connection to the port was still being considered and was included in the "Metromover Expansion Master Plan".

The FEC freight railroad spur to PortMiami was renovated and returned to service in the early 2010s. In addition, the construction that began on stations and double tracking of the mainline in South Florida as part of the All Aboard Florida intercity rail system could potentially foster in future heavy rail passenger service to the port.

Various enhanced connections to Port Everglades have also been proposed over the years, including the long-term plan for the Wave Streetcar. In the 2000s and 2010s, road access to the port via I-595 was improved.

Dolphin Expressway extension - Krome Avenue widening

There is a controversial plan to extend the Dolphin Expressway from its current western terminus further west to the edge of the Everglades, then south through rural areas, with Krome Avenue being the primary alignment proposed. Controversy surrounds whether such an alignment, located outside of the Urban Development Boundary and near a fragile ecosystem, would encourage more sprawl and suburban development in an already congested region. Known as the "southwest extension," it would carry the expressway south to Southwest 136 Street in Country Walk, adjacent to Kendall–Tamiami Executive Airport. The project drew mixed reaction from local residents in an informal public awareness meeting held by the Miami-Dade Expressway Authority in 2014. Beginning in 2015, a controversial widening of Krome Avenue began from Okeechobee to the Tamiami Trail, followed by the next segment from Tamiami to Kendall Drive. While not a limited-access highway, the project adds a median and brings the road to four lanes. Eventually the southern portion from Kendall Drive to the southern terminus at US-1 in Florida City, through more developed areas, is expected to be widened as well.

Physical expansion of the urbanized area in southern Florida is constrained by its location between the Atlantic Ocean to the east and the federally protected Everglades wetlands to the west. Though there is more land that can legally be developed before cutting in to Everglades National Park, Miami-Dade County has a politically defined Urban Development Boundary (UDB), which is only amended to allow further development after due process, with considerations such as population growth and amount and location of undeveloped land available within the UDB. This trend lends itself to increasing density within the urbanized area, with a focus on areas with transit; however, most of the expansions of the UDB are for low-density residential developments of less than five units per acre. This contrasts sharply with the downtown Miami area, where zoning allows development up to 1,000 units per acre, and zoning allowances are amended as the downtown area expands.

Hurricanes pose a substantial threat to infrastructure along the entire east coast of the United States, with Miami being ranked one of the most threatened major cities in terms of potential financial loss due to storms and climate change, along with New York City. Particularly, Miami is considered one of the most vulnerable cities worldwide in terms of possible sea level rise, with Miami Beach experiencing annual tidal flooding. The county claims that regular service on transportation systems will be suspended before sustained winds reach 39 miles per hour (63 km/h) in anticipation of tropical weather. Miami-Dade Transit will use its rolling stock as emergency vehicles to transport people to and from emergency shelters in the event of an evacuation order.

In addition to present difficulty with below-grade development, some areas of southern Florida, especially Miami Beach, are beginning to engineer specifically for sea level rise and other potential effects of climate change. This includes a five-year, US$500 million project for the installation of 60 to 80 pumps, building of taller sea walls, and the physical raising or road tarmac levels, as well as possible zoning and building code changes, which could eventually lead to retrofitting of existing and historic properties. Miami Beach sees sunny day flooding of certain roads during the annual king tides, though some argue this has been the case for decades, as the parts of the western side of South Beach are at virtually 0 feet (0 m) above normal high tide, with the entire city averaging only 4.4 feet (1.3 m) above mean sea level (AMSL). A study by the University of Miami Rosenstiel School of Marine and Atmospheric Science of Miami Beach flooding incidents from 1998 to 2013 tidal flooding was increasing with time, coinciding with an increase in the rate of sea level rise locally. The fall 2015 king tides exceeded expectations in longevity and height. Some streets and sidewalks were raised about 2.5 feet (0.76 m) over previous levels; the four initial pumps installed in 2014 are capable of pumping 4,000 US gallons per minute. Several other cities in the county already have building codes that exceed Federal Emergency Management Agency (FEMA) mandates. Traditional sea level rise and storm mitigation measures including sea walls and dykes, such as those in the Netherlands and New Orleans, may not work in South Florida due to the porous nature of the ground and limestone beneath the surface. More than half of South Florida is under 6 feet (1.8 m) AMSL, while the highest elevations, made up of a limestone ridge that includes Brickell Hammock, averages only 12 feet (3.7 m). Fort Lauderdale sees increasing tidal flooding as well, exacerbated by its extensive inland canal system. They are combating the problem with one-way valves retrofitted into the drainage system, and are considering using pumps as well. Development booms in the 21st century began raising questions of the sustainability of coastal habitation, given that South Florida's approximate population of six million makes up nearly half of the estimated 13.1 million people who would be affected by a 1.8 m (5.9 ft) increase in sea level possible by 2100.

Although often grouped with other relatively young sunbelt cities, which grew largely in the age of the automobile, Miami and Coral Gables had an extensive early transit system, with a peak in the 1920s. In the city's early years, following its incorporation in 1896, there were several de facto streetcar or trolley systems, many of which were short-lived. The first known electric streetcar was an interurban that operated circa 1906, operated by the Miami Electric Railway Company. Another streetcar began operation in 1909 and was short-lived; another battery-powered streetcar was introduced in 1915 by the Miami Traction Company. It wasn't until 1922 that the more widely known electric streetcar system was implemented, using an extensive overhead catenary. It operated a high-speed line from Miami to Ponce de Leon Boulevard in Coral Gables via Coral Way beginning in 1925. The decline and demise of the streetcars took place over the 1930s, a decade which included the devastating setback of the Coral Gables to Miami route being damaged by the 1935 Labor Day Hurricane; followed by closure of Miami Beach Railway Co. service to Miami Beach via the MacArthur Causeway in 1939, with the system officially closing in 1940 to be replaced with bus service.

The majority of plans to return "streetcar" service to Miami's since 2006 consist of rubber-tired trolleys with no priority in traffic.

Henry Flagler's Florida East Coast Railway passenger service reached Miami the same year it was incorporated as a city, in 1896.

The modern Miami-Dade Transit county agency was created in 1960 as the Metropolitan Transit Authority (MTA), effectively marking the end of privately operated large scale public transportation services in the county, though there continued to be jitneys or minibuses. Miami Urban Area Transportation Study (MUATS) studies for the feasibility of mass transit in Miami-Dade County began in 1964. These studies, which were supplemented by reports by Simon & Curtin Transportation Engineers, continued into the 1970s and recommended a public transit system for the county, citing traffic problems and increasing population. In 1969, a 67-mile (108 km) grade-separated rapid transit system was proposed. It placed priority on connecting Miami Beach to Miami International Airport via downtown and the Port of Miami. Although the AirportLink finally brought rapid transit to the airport in 2012, transit off the mainland is still considered difficult and convoluted due to the remaining absence of a link to the beach.
