Rock Island is a city in Illinois, located in Rock Island County. In 2020, about 37,108 people lived here. The city sits where the Rock River meets the mighty Mississippi River.

Rock Island is one of the five Quad Cities. These cities include Moline and East Moline in Illinois, and Davenport and Bettendorf in Iowa. Together, the Quad Cities area had over 384,000 people in 2020.

The city is home to Rock Island Arsenal. This is the largest government-owned factory in the U.S. that makes weapons for the U.S. Army. It employs about 6,000 people. The island that gave the city its name is now called Arsenal Island.

Rock Island's Past

Rock Island has a long and interesting history. It was first a great spot for people to settle. Later, it became important for riverboats, bridges, and trains.

Early Settlements

The first part of what is now Rock Island was called Farnhamsburg. This name came from the first two homes built there in 1826. Colonel George Davenport and Russell Farnham built these homes. They were business partners who traded with the local Native Americans.

The city was officially planned on July 10, 1835, and was first named Stephenson. It was renamed Rock Island in March 1841.

The southern part of Rock Island was known as Searstown. It was named after David B. Sears. He built the Sears Power Dam on the Rock River. Searstown became part of Rock Island in 1915.

Trains and Growth

The Chicago, Rock Island & Pacific Railroad (RI) started here in 1851. People often called it the Rock Island Line. Over the next 100 years, this railroad grew to serve 14 states. However, it went out of business in 1980.

In the late 1800s, two fancy hotels were built in town. These were the Harper House (opened in 1871) and the Rock Island House. The Rock Island Arsenal has been making military equipment for the U.S. Army since the 1880s.

The Rock Island Southern Railway was an electric train line. It ran from Rock Island to Monmouth, Illinois, and then to Galesburg, Illinois. It was built between 1906 and 1910. This line closed in 1952.

Amazing Bridges

Rock Island has many bridges because of its location. It even had the first railroad bridge across the Mississippi River! It also has a unique two-track railroad bridge and the world's largest roller dam.

The first railroad bridge across the Mississippi River was built in 1856. It connected Arsenal Island and Davenport. Many steamboat captains did not like this bridge. They felt it made it hard for their boats to pass. This led to a big argument between St. Louis (with its steamboats) and Chicago (with its railroads).

Just two weeks after the bridge opened, a steamboat called the Effie Afton hit the bridge. It caught fire and damaged the bridge. The steamboat owner sued the bridge company. Abraham Lincoln was one of the lawyers who defended the railroad in court in 1857. The case went all the way to the U.S. Supreme Court. In 1862, the Supreme Court decided in favor of the railroad.

The original bridge is no longer there. A stronger bridge replaced it in 1866. You can find a monument on Arsenal Island marking where the Illinois side of the first bridge was.

Rock Island System Map
The Rock Island Line moved goods from west of the Mississippi, across the bridge at Rock Island, east to Chicago. This map shows the railroad's size in 1965.

The Lock and Dam No. 15 and the Government Bridge are near where the first bridge stood. The Government Bridge, finished in 1896, is special. It has two sets of train tracks above the car lanes. Only two bridges in the world have this feature!

Three other bridges cross the river between Rock Island and Davenport. The Crescent Rail Bridge is only for trains and was finished in 1899. The Centennial Bridge was built in 1940 for cars. The newest bridge is the Interstate 280 bridge, finished in 1973.

Lock and Dam No. 15 was completed in 1934. It was a project during the Great Depression. It is the largest roller dam in the world. This dam helps boats travel on the river. It is not for flood control. During floods, the rollers are lifted to let the water flow freely.

On the south side of the city, near the Black Hawk State Historic Site, are bridges over the Rock River to Milan, Illinois. These bridges also cross the old Hennepin Canal and Sears Dam. In 2007, a new bridge was finished. It makes it faster to get to Milan, the airport, and places south on U.S. Route 67.
