Interstate 280 marker

Interstate 280 (I-280) is a 57-mile (92-km) long north–south Interstate Highway in the San Francisco Bay Area of Northern California. It connects San Jose and San Francisco, running along just to the west of the larger cities of San Francisco Peninsula for most of its route.

I-280 from its southern terminus at U.S. 101 and Interstate 680 north to Interstate 880 in San Jose is part of the Sinclair Freeway (named after Joseph P. Sinclair, District Engineer for District 4 California Division of Highways). From I-880 to State Route 1 in Daly City, I-280 was built and dedicated as the Junipero Serra Freeway, after the Spanish Franciscan friar who founded the first nine of 21 Spanish missions in California from San Diego to San Francisco. One of the dedication signs (in Daly City) still indicates that the Junipero Serra Freeway is known as the "World's Most Beautiful Freeway" due to its scenic route through the San Francisco Peninsula. From State Route 1 to the James Lick Freeway (U.S. 101) in San Francisco it is officially called the John F Foran Freeway (after a former member of the California State Legislature), but is more commonly referred to by its original name, the Southern Freeway. And from the James Lick Freeway to its northern end at King Street and Fifth Street, I-280 is called the Southern-Embarcadero Freeway.
