Interstate 880 (I-880) is a north–south auxiliary Interstate Highway in the San Francisco Bay Area of Northern California. It runs from I-280 and State Route 17 (SR 17) in San Jose to I-80 and I-580 in Oakland, running parallel to the eastern shore of San Francisco Bay. For most of its route, I-880 is officially known as the Nimitz Freeway, after World War II fleet admiral Chester W. Nimitz, who retired to the Bay Area. The northernmost is also commonly referred to as the Cypress Freeway, after the former alignment of the freeway and its subsequent replacement.
Route description

The entirety of I-880 is defined in section 625, subdivision (a) of the California Streets and Highways Code as Route 880, and that the highway is from "Route 280 to Route 80 in Oakland".
In addition, section 325 subdivision (b), last amended by the California State Legislature in 2001, permits the state to relinquish the former right-of-way of Route 880 located along the now-demolished Cypress Street Viaduct between 8th and 32nd streets to the City of Oakland.
I-880 is part of the California Freeway and Expressway System and is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration (FHWA). Officially, the Nimitz Freeway designation is Route 880 from Route 101 to Route 80, as named by Senate Concurrent Resolution 23, Chapter 84 in 1958.
Since the late 1990s, an infamous misconception for certain commuters and businesses in San Jose is that I-880 extends from I-280 to SR 85 in Los Gatos (which would extend the length to ).
Express lanes
High-occupancy toll (HOT) lanes along I-880 between the Milpitas–Fremont line at Dixon Landing Road and Lewelling Boulevard in San Lorenzo opened in October 2020. The southbound express lanes extend north to Hegenberger Road in Oakland and south to SR 237 in Milpitas.
, the HOT lanes' hours of operation is weekdays between 5:00 am and 8:00 pm; they are otherwise free and open to all vehicles at other times. Solo drivers are tolled using a congestion pricing system based on the real-time levels of traffic. Two-person carpools are charged 50 percent of the posted toll. Carpools with three or more people and motorcycles are not charged. All tolls are collected using an open road tolling system, and therefore there are no toll booths to receive cash. Each vehicle using the HOT lanes is required to carry a FasTrak Flex transponder with its switch set to indicate the number of the vehicle's occupants (1, 2, or 3+). Solo drivers may also use the FasTrak standard tag without the switch. Drivers without any FasTrak tag will be assessed a toll violation regardless of whether they qualified for free.
History
thumb|left|The [[Oakland Airport Connector traverses I-880 in Oakland, with Oakland Coliseum and Arena right of center]]
The state legislature added the proposed San Jose–Richmond East Shore Highway to the state highway system in 1933, and it became an extension of the previously short (San Rafael to the bay) Legislative Route (LRN) 69, and part of Sign Route 13 (soon changed to 17) in 1934. From San Jose, this route temporarily followed existing LRN 5 (present Oakland Road, Main Street, Milpitas Boulevard, and Warm Springs Boulevard) to SR 21 at Warm Springs and then continued along existing county roads and city streets, now known as Fremont Boulevard, Alvarado Boulevard, Hesperian Boulevard, Lewelling Boulevard, Washington Avenue, 14th Street, 44th Avenue, 12th Street, 14th Avenue, 8th Street, and 7th Street<!--not shown on the topos, but shown on Gousha and in the definition of Route 105 - it was later a one-way pair-->, into Downtown Oakland. It then turned north at Cypress Street (now Mandela Parkway), passing through the MacArthur Maze and following a newly constructed alignment (signed as US 40) to El Cerrito.<!--when did construction begin?-->
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,<!--why does it say it's the third?--> 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<!--was part of it through downtown finished earlier?--> 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 LRN 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).
Historic alignments
SR 17
Prior to 1984, the route known as I-880 used to be part of SR 17, which was US 48
Nimitz Freeway
In 1947, construction commenced on a freeway to replace the street routing of SR 17 through the East Bay. The new freeway was named the "Eastshore Freeway", and, with the subsequent addition of a freeway to replace the Eastshore Highway north of the MacArthur Maze in the mid 1950s, it ran, appropriately, almost the entire length of the east shore of San Francisco Bay. In 1958, following a joint resolution of the California State Legislature, the portion south of the MacArthur Maze was renamed the Nimitz Freeway in honor of WWII Admiral Nimitz, while the portion to the north retained the name Eastshore Freeway. The formal dedication, with the participation of Admiral Nimitz, took place on August 12, 1958.
Historic US 50 Bus.
The northern portion of I-880 was designated US 50 Business (US 50 Bus.) for a time between the I-80 interchange and Downtown Oakland.
Original routing in Sacramento
From 1971 to 1983, I-880 was the original route designation for the Beltline Freeway, the northern bypass freeway for the Sacramento area. This freeway begins in West Sacramento as a fork from the original I-80, continues northeast over the Sacramento River to its interchange with I-5, continues east through the communities of North Sacramento and Del Paso Heights, and ends at an interchange with the Roseville Freeway (I-80). The now-designated Capital City Freeway was then the original I-80 routing, continuing southwest directly into Downtown Sacramento. I-80 was then rerouted along the Beltline Freeway in 1983, while the Capital City Freeway became I-80 Bus.
Modern history
Cypress Viaduct and the 1989 Loma Prieta earthquake
thumb|Portion of the collapsed Cypress Viaduct in Oakland
A large double-decker section in Oakland, known as the Cypress Street Viaduct, collapsed during the 1989 Loma Prieta earthquake, causing 42 deaths; initial estimates were significantly higher, but, because many commuters on both sides of the bay had left early or stayed late to watch Game 3 of the San Francisco–Oakland World Series, the freeway was far less crowded than normal at the time of the quake.
Due to environmental impact concerns, and the desire by the West Oakland community to reconnect the neighborhood with the rest of the city, among other reasons, a new route was selected along an industrial area and railroad yard around the outskirts of the neighborhood. Although only about in length, the replacement freeway cost over $1.2 billion (equivalent to $ in ), and did not open until 1997 for several reasons: it crossed over and under the elevated Bay Area Rapid Transit (BART) line to San Francisco; it squeezed between a post office, the West Oakland station, the Port of Oakland, a railyard, and an East Bay Municipal Utility District 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 it had to be earthquake resistant. Furthermore, a new interchange was constructed south of Grand Avenue, where ramps connect to I-80 west via a viaduct crossing the rail tracks and Grand Avenue, avoiding the MacArthur Maze completely; A new flyover exit ramp to I-80 east was also constructed to cross over the existing MacArthur Maze structure.
Sound barriers
Due to high sound levels generated from this highway and the relatively dense urban development in the highway corridor, the California Department of Transportation (Caltrans) has conducted numerous studies to retrofit the right-of-way with noise barriers. This activity has occurred in Oakland, San Leandro, Hayward, Newark, and Fremont. During the 1989 widening of I-880 in parts of Newark and Fremont, scientific studies were conducted to determine the need for sound walls and to design optimum heights to achieve Federal noise standards.
No interchange with SR 87/Guadalupe Freeway

Between Coleman Avenue and 1st Street in San Jose, SR 87 (Guadalupe Freeway) crosses above I-880 without an interchange, making it the only point in California where two freeways cross without a connection. Because of its proximity to the runways at San Jose International Airport, Caltrans cannot construct elevated ramps without them interfering with flight paths. Tunneling underneath to build underground ramps would also make a significant environmental impact to the nearby Guadalupe River.
2012–2015 I-880/I-280 interchange improvement
Improvements to the I-280/I-880 and Stevens Creek Boulevard interchanges finished early 2015. Changes included breaking up the handful of ramps that both interchanges shared so they would be independent from one another. Construction began in late 2012 and the ramp from I-280 north to I-880 north opened in April 2015.
I-880 Corridor Improvement Project
The I-880 Corridor Improvement Project, one of the last seismic retrofit projects of a major transportation corridor in California, consisted of eight separate projects located in a segment of the freeway between Oakland and Hayward.
The overall goal of the project was to improve the seismic safety of the corridor. After the 1989 Loma Prieta earthquake, Caltrans initiated Phase 1 of its seismic retrofit program. After the 1994 Northridge earthquake, Caltrans initiated Phase 2 of its seismic retrofit program, which included projects along the I-880 corridor. Other goals include reducing traffic congestion and improving road quality.
The individual projects included in the I-880 Corridor Improvement Project were retrofitting or replacing the 5th Avenue, 23rd Avenue, 29th Avenue, Fruitvale Avenue, and High Street bridges in Oakland; improvements to both the I-238 and SR 92 interchanges (the latter, a four-year project, completed in October 2011); and an overall rehabilitation/repaving project along the entire segment. Construction began in 2006, although certain projects were completed in 2020. The total cost of the project is $462.7 million (equivalent to $ in ), provided by federal, state, and regional funds.
