Interstate 880 is a regional bypass interstate highway in the Bay Area metropolitan area of Northern California. For most of that distance, it runs parallel to the southeastern shore of San Francisco Bay, where it is called the Nimitz Freeway, after World War II admiral Chester Nimitz, who retired to the Bay Area.

The northern terminus is in Oakland at the junction with Interstate 80 and Interstate 580 (known as the MacArthur Maze), near the eastern approach of the Bay Bridge. The southern terminus is at Interstate 280 in San Jose.

Notes

Cypress Viaduct Loma Prieta earthquake 1989

Portion of the collapsed Cypress Viaduct in Oakland.

A large double-decker section in Oakland, known as the Cypress Viaduct , collapsed during the 1989 Loma Prieta earthquake, causing 42 deaths, the greatest loss of life of that earthquake. Rebuilding that section of the freeway took nearly a decade, due to environmental impact concerns, the feeling that the freeway divided the neighborhood, and design considerations. The highway was rebuilt on a new route around the outskirts of West Oakland, and the path of the former Cypress Structure was turned into a wide boulevard.

California Highway 17

South of Interstate 280 in San Jose, Interstate 880 loses its interstate designation and becomes California Highway 17. Until it was given interstate status in January 1986, however, the present-day Interstate 880 was designated as California Highway 17 along its entire route, from Santa Cruz to Oakland.

Sacramento bypass

Interstate 880 was at one time designated as a bypass of Sacramento. Its route is now used by Interstate 80.

Historic Business U.S. Highway 50

The northern portion of I-880 was designated Business Route U.S. Highway 50 before it became part of the interstate system.
