Interstate 110 and State Route 110

Interstate 110 and State Route 110 form a major north-south corridor that runs from the port area through downtown Los Angeles toward Pasadena. The system includes the Harbor Freeway and the Arroyo Seco Parkway, with multiple lanes and elevated sections that navigate the city's terrain.

The Arroyo Seco Parkway section, finished in 1940, became the first freeway built in the western United States and kept many of its original architectural details. The broader Interstate 110 system grew over the following decades as part of the nation's highway expansion.

The route passes through neighborhoods where you can see how Los Angeles connects different communities, from the port area to residential and cultural centers, shaping how people move across the city.

Expect heavy traffic during morning and evening rush hours when traveling this route, as it is one of the busiest corridors in the region. Free standard lanes are available for all drivers alongside toll lanes for carpools and solo drivers willing to pay for faster travel.

In 2001, an artist created and installed realistic directional signs along the highway that authorities didn't remove for eight years because they were accurate and appeared official. The project became an unusual example of subtle street art that blended seamlessly with real infrastructure.
