Interstate 5 (I-5) is the main Interstate Highway on the West Coast of the United States, running largely parallel to the Pacific coast of the contiguous U.S. from Mexico to Canada. It travels through the states of California, Oregon, and Washington, serving several large cities on the U.S. West Coast, including San Diego, Los Angeles, Sacramento, Portland, and Seattle. It is currently the only continuous Interstate highway to touch both the Mexican border and the Canadian border. Upon crossing the Mexican border at its southern terminus, Interstate 5 continues to Tijuana, Baja California as Mexico Federal Highway 1. Upon crossing the Canadian border at its northern terminus, it continues to Vancouver as British Columbia Highway 99.

It is the second-longest Interstate Highway in the United States, following I-90.

Interstate 580 (I-580) is an 80-mile (129 km) east–west Interstate Highway in Northern California. The heavily traveled spur route of Interstate 80 runs from San Rafael in the San Francisco Bay Area to Interstate 5 near Tracy in the Central Valley.

Interstate 780 (I-780) is an Interstate Highway in the San Francisco Bay Area of the U.S. state of California. It serves to connect Interstate 80 in Vallejo with Interstate 680 just north of the Benicia-Martinez Bridge in Benicia. It closely parallels the Carquinez Strait for its entire route. Originally, this segment was part of I-680 before that Interstate was extended and rerouted to Fairfield. The city-maintained Curtola Parkway continues west from I-80 to State Route 29 in Vallejo.
Interstate 380 (I-380) is a short 1.7-mile (2.7 km) east–west spur Interstate Highway in the San Francisco Bay Area of Northern California, connecting Interstate 280 in San Bruno to U.S. Route 101 near the San Francisco International Airport (SFO). The highway primarily consists of only three intersections: I-280, El Camino Real, and U.S. 101. Like the nearby I-280, I-380 never connects to Interstate 80, its parent Interstate Highway. However, there is no rule that says that spur routes need to.
The Santa Ana Freeway is one of the principal freeways in Southern California, connecting Los Angeles and its southeastern suburbs including the freeway's namesake, the city of Santa Ana. The freeway begins at its junction with the San Diego Freeway, called the El Toro Y, in Irvine, signed as I-5. From there, it generally goes southeast to northwest to the East Los Angeles Interchange, where it takes the designation of U.S. Route 101 (US 101). It then proceeds 2.95 miles (4.75 km) northwest to the Four Level Interchange in downtown Los Angeles.

For most of its length, especially in Downtown San Jose, the highway follows the course of the Guadalupe River. Its southern terminus is at SR 85, and its northern terminus is at U.S. Route 101 just north of San Jose International Airport. Unusually, it crosses over Interstate 880 (I-880) without an interchange.
