Interstate 110 and State Route 110 (California) facts for kids

Interstate 110 (I-110) and State Route 110 (SR 110) are two important highways in Los Angeles County, California. They are connected, meaning they flow into each other. These roads help people travel between the Port of Los Angeles and the city of Pasadena, passing right through Downtown Los Angeles. The part of the road from the Port of Los Angeles up to Interstate 10 is called Interstate 110. After that, from Interstate 10 to Pasadena, it becomes State Route 110. The entire route is also known as the Harbor Freeway. It is about 32 miles (51 kilometers) long.

What are I-110 and SR 110?

These highways are special types of roads called controlled-access highways. This means you can only get on or off them at specific points called exits. This helps traffic flow smoothly and safely. The Harbor Freeway is a very busy road, especially during rush hour, because it connects many parts of Los Angeles.

The Harbor Freeway

The name "Harbor Freeway" is used for the southern part of the route, which is Interstate 110. This section starts near the Port of Los Angeles in San Pedro. It travels north through many communities like Carson and Wilmington before reaching Downtown Los Angeles. This part of the freeway is vital for moving goods from the port and for people commuting to work or school.

The Arroyo Seco Parkway

When the highway passes Interstate 10 in Downtown Los Angeles and continues north towards Pasadena, it changes from I-110 to SR 110. This northern part is also known as the Arroyo Seco Parkway. This parkway is very old and has a lot of history. It was one of the first freeways built in the Western United States. Because of its history and unique design, it's considered a National Scenic Byway and a California Historic Parkway. Driving on this section can feel a bit different from modern freeways because it was designed a long time ago.

Connecting to Other Roads

Highways like I-110 and SR 110 are important because they connect to many other major roads, making it easier to travel across Los Angeles and beyond. Along its route, the I-110 and SR 110 connect with several other large freeways:

• Interstate 405 (the San Diego Freeway) in Carson.
• State Route 91 (the Gardena Freeway) in Los Angeles.
• Interstate 105 (the Glenn Anderson Freeway), which can take you to LAX Airport.
• Interstate 10 (the Santa Monica Freeway) in Downtown Los Angeles. This is where I-110 officially becomes SR 110.
• U.S. Route 101 in Downtown Los Angeles, connecting to areas like Hollywood.
• Interstate 5 (the Golden State Freeway), which is a major route running through California.

These connections help millions of people get to different parts of the city and state every day.
