Interstate 880 (I-880) is an interstate highway in the San Francisco Bay Area connecting San Jose and Oakland, running parallel to the southeastern shore of San Francisco Bay. For most of its route, I-880 is officially known as the Nimitz Freeway after World War II admiral Chester Nimitz, who retired to the Bay Area. It is nicknamed "The Nasty Nimitz" due to its rush hour traffic levels.
This route is part of the California Freeway and Expressway System.

The southern terminus of I-880 is at its interchange with Interstate 280 and State Route 17 in San Jose. From there, it heads roughly northeast past the San Jose International Airport to U.S. Route 101. The Nimitz Freeway then turns north, running parallel to the southeastern shore of San Francisco Bay, connecting the cities of Milpitas, Fremont, Newark, Union City, Hayward, and San Leandro before reaching Oakland. The northern terminus of I-880 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 Nimitz Freeway is Route 880 from Route 101 to Route 80, as named by Senate Concurrent Resolution 23, Chapter 84 in 1958.
The first short piece of the new Eastshore Freeway opened to traffic on July 22, 1949, connecting Oak Street downtown with 23rd Avenue. It was extended to 98th Avenue on June 1, 1950, Lewelling Boulevard on June 13, 1952, and Jackson Street (SR 92) on June 5, 1953. At the San Jose end, the overlap with Route 5 between Bayshore Highway (US 101) and Warm Springs was bypassed on July 2, 1954. Within Oakland, the double-decker Cypress Street Viaduct opened on June 11, 1957, connecting the freeway with the San Francisco – Oakland Bay Bridge. The Oakland segment was extended south to Fremont Boulevard at Beard Road on November 14, 1957, and the gap was filled on November 24, 1958, soon after the state legislature named the highway after Fleet Admiral Chester W. Nimitz. (The short spur to Route 5 at Warm Springs (now SR 262) remained in the state highway system as a branch of Route 69.) As these sections opened, Sign Route 17 (and Legislative Route 69) was moved from its old surface routing, which mostly became local streets. Other than Route 5 south of Warm Springs, the portion from San Leandro into Oakland was also kept as part of Route 105 (now SR 185).
Prior to 1984, the route known as I-880 used to be part of State Route 17. SR 17 used to run from Santa Cruz all the way though San Jose, Oakland; and then continued north via the Eastshore Freeway (Interstate 80) through Richmond to the Richmond-San Rafael Bridge and San Rafael.
In 1984 the segment of SR 17 from Interstate 280 in San Jose to the MacArthur Maze in Oakland was renumbered as I-880, and the portion of SR 17 from the MacArthur Maze to San Rafael was renumbered as part of I-580.
A large double-decker section in Oakland, known as the Cypress Street Viaduct, collapsed during the 1989 Loma Prieta earthquake, causing 42 deaths. This was the greatest loss of life caused by that earthquake. Rebuilding the affected 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 freeway reopened in 1997 on a new route parallel to railroad tracks around the outskirts of West Oakland.
Although only about three miles (5 km) in length, the replacement freeway cost over $1.2 billion, for several reasons: it crossed over and under the elevated BART line to San Francisco; it squeezed between a post office, the West Oakland BART station, the Port of Oakland, a rail yard, and a sewage treatment plant; it occupied an entirely new right-of-way, which required the acquisition of large amounts of valuable industrial real estate near the Port of Oakland; and of course, it had to be earthquake-proof.
The former path of the structure, Cypress Street, was renamed Mandela Parkway, and the median where the freeway stood became a landscaped linear park.
