Interstate 210
Explore Interstate 210, the Foothill Freeway, spanning 85 miles across Southern California. Learn about its route, key interchanges, and role as a major east-west bypass of I-10.
Interstate 210, often referred to as the Foothill Freeway, serves as a vital east-west corridor across Southern California, primarily within Los Angeles and San Bernardino counties. Stretching approximately 85 miles, I-210 connects I-5 in Sylmar to I-10 in Redlands, acting as a bypass route for the heavily traveled I-10 corridor through the Los Angeles basin. This route is instrumental in easing commuter traffic and providing alternative access to destinations throughout the San Gabriel Valley, Inland Empire, and foothill communities.
The western segment of I-210 runs parallel to the San Gabriel Mountains, passing through cities like Pasadena, Arcadia, Monrovia, and Glendora before transitioning briefly into State Route 210 near La Verne. Though the numbering differs slightly, the entire corridor functions as a continuous freeway system. As drivers head east beyond San Dimas, SR-210 resumes the Interstate designation in Rialto, continuing through San Bernardino and terminating in Redlands, where it merges with I-10.
I-210 is not just a commuter route — it’s also a scenic drive through diverse urban and suburban landscapes. Along the way, it connects with major interstates such as I-5, I-605, I-15, and I-10, providing key access points for both local and long-distance travelers. Whether you’re navigating weekday traffic or exploring Southern California’s varied terrain, Interstate 210 is a strategic link in the region’s highway system.
