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 five miles (8.0 km) is also commonly referred to as the Cypress Freeway, after the former alignment of the freeway and its subsequent replacement.
The southern terminus of I-880 is at its interchange with I-280 and SR 17 in San Jose. From there, it heads roughly northeast past San Jose International Airport to US Route 101 (US 101). The Nimitz Freeway then turns northwest, 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. In Oakland, I-880 passes by Oakland International Airport, Oakland Coliseum, the Port of Oakland, and Downtown Oakland. The northern terminus of I-880 is in Oakland at the junction with I-80 and I-580 (known as the MacArthur Maze), near the eastern approach of the San Francisco–Oakland Bay Bridge.
I-880 between I-238 in San Leandro and the MacArthur Maze is used as the main truck route; trucks over 4.5 short tons (4.1 t; 4.0 long tons) are prohibited through Oakland on I-580. [3]
I-880 is part of the California Freeway and Expressway System [4] and is part of the National Highway System, [5] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration (FHWA). [6] 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. [7]
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 50 miles [80 km]).
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. [8]
As of August 2022 [update] , the HOT lanes' hours of operation is weekdays between 5:00 am and 8:00 pm. Solo drivers are tolled using a congestion pricing system based on the real-time levels of traffic. Two-person carpools and clean air vehicles with a solo driver are charged 50 percent of the posted toll. Carpools with three or more people and motorcycles are not charged. [9] All tolls are collected using an open road tolling system, and therefore there are no toll booths to receive cash. Each vehicle is required to carry either a FasTrak Flex or CAV (Clean Air Vehicle) transponder, with its switch set to indicate the number of the vehicle's occupants (one, two, three, or more). Solo drivers may also use the FasTrak standard tag without the switch. [9] Drivers without any FasTrak tag will be assessed a toll violation regardless of whether they qualified for free. [10]
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, [11] [12] and part of Sign Route 13 (soon changed to 17) in 1934. [13] 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, [14] 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, 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. [15] [16] [17] [18] [19] [20]
The first short piece of the new Eastshore Freeway opened to traffic on July 22, 1949, connecting Oak Street downtown with 23rd Avenue. [21] [22] It was extended to 98th Avenue on June 1, 1950, [23] Lewelling Boulevard on June 13, 1952, [24] and Jackson Street (SR 92) on June 5, 1953. [25] At the San Jose end, the overlap with Route 5 between Bayshore Highway (US 101) and Warm Springs was bypassed on July 2, 1954. [26] Within Oakland, the double-decker Cypress Street Viaduct opened on June 11, 1957, connecting the freeway with the San Francisco–Oakland Bay Bridge. [27] The Oakland segment was extended south to Fremont Boulevard at Beard Road on November 14, 1957, [28] and the gap was filled on November 24, 1958, [29] soon after the state legislature named the highway after Fleet Admiral Chester W. Nimitz. [30] (The short spur to Route 5 at Warm Springs (now SR 262) remained in the state highway system as a branch of Route 69. [31] ) 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). [32]

Prior to 1984, the route known as I-880 used to be part of SR 17, which was US 48 [33] from current I-238 to US 101 from 1926 to 1931, then US 101E from 1929 to the mid-1930s. SR 17 used to run from Santa Cruz all the way through San Jose, Oakland, and then continued north via the Eastshore Freeway (I-80) through Richmond to the Richmond–San Rafael Bridge and San Rafael.
In 1984, the segment of SR 17 from I-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.
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. [34] [35] [36] 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.

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.
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. [38] 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, design considerations, and, most importantly, a huge outcry from the West Oakland community demanding that the freeway find a new route–not in West Oakland. The protest was successful. The freeway reopened in July 1997 on a new route parallel to railroad tracks around the outskirts of West Oakland with the entire project being opened in 1999 and fully completed in 2001, with the replacement taking on the commonly referred to name of Cypress Freeway, much like the former double-decker freeway.
Although only about three miles (4.8 km) in length, the replacement freeway cost over $1.2 billion (equivalent to $1.71 billion in 2020 [39] ) for several reasons: it crossed over and under the elevated Bay Area Rapid Transit (BART) line to San Francisco; it squeezed between a postoffice, 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, of course, it had to be earthquake resistant. [40]
The former path of the structure, Cypress Street, was renamed Mandela Parkway, and the median where the freeway stood became a landscaped linear park. [41]
Several aspects of the I-880 facility have been constructed in designated floodplains such as the 1990 and 2004 interchange improvements at Dixon Landing Road. In that case, the FHWA was required to make a finding that there was no feasible alternative to the new ramp system as designed. In that same study, the FHWA produced an analysis to support the fact that adequate wetlands mitigation had been designed into the improvement project. [42]
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. [43]
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. [44] 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. [44]
On April 29, 2007, a gasoline tanker overturned and caught fire on the connector between westbound I-80 and southbound I-880 on the MacArthur Maze interchange. The fire caused major damage to both this connector and one directly above (eastbound I-80 onto eastbound I-580). The overpass was replaced and reopened 27 days later. The governor, Arnold Schwarzenegger, declared it as a state of emergency and all public transportation was free on the first commute day. [45]
Improvements to the I-280/I-880 and Stevens Creek Boulevard interchanges finished early 2015. Before construction, both interchanges shared a handful of ramps, but now, the two interchanges will 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. [46]
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 15-mile (24 km) segment of the freeway between Oakland and Hayward. [47] [48]
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. [49] Other goals include reducing traffic congestion and improving road quality. [50]
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); [51] 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, provided by federal, state, and regional funds.

Interstate 580 (I-580) is an approximately 76-mile-long (122 km) east–west auxiliary Interstate Highway in Northern California. The heavily traveled spur route of I-80 runs from US Route 101 (US 101) in San Rafael in the San Francisco Bay Area to I-5 at a point outside the southern city limits of Tracy in the Central Valley. I-580 forms a concurrency with I-80 between Albany and Oakland, the latter of which is the location of the MacArthur Maze interchange immediately east of the San Francisco–Oakland Bay Bridge. I-580 provides a connection from the Bay Area to the southern San Joaquin Valley and Southern California via I-5, as I-5 bypasses the Bay Area to the east.
Interstate 980 (I-980) is a short 2.03-mile (3.27 km) auxiliary Interstate Highway entirely within Oakland in Northern California, connecting I-580 and State Route 24 (SR 24) to I-880 near Downtown Oakland. I-980 passes the Oakland Convention Center and near the famous Jack London Square. I-980 is commonly considered the dividing line between Downtown Oakland and West Oakland. The freeway was planned as the eastern approach to the Southern Crossing. It is officially known as the John B. Williams Freeway, after the former director of the city of Oakland's Office of Community Development.
Interstate 680 (I-680) is a north–south auxiliary Interstate Highway in Northern California. It curves around the eastern cities of the San Francisco Bay Area from San Jose to I-80 at Fairfield, bypassing cities along the eastern shore of San Francisco Bay such as Oakland and Richmond while serving others more inland such as Pleasanton and Concord.
Interstate 280 (I-280) is a 57.22-mile-long (92.09 km) major north–south auxiliary Interstate Highway in the San Francisco Bay Area of Northern California. It runs from I-680 and US Route 101 (US 101) in San Jose to King and 5th streets in San Francisco, running just to the west of the larger cities of San Francisco Peninsula for most of its route.
State Route 85, known as the West Valley Freeway along its entire length, is a state highway which connects the cities of southern San Jose and Mountain View in the U.S. State of California. The highway intersects with major highways such as I-280, SR 17, and SR 87. The route provides an alternate to U.S. Route 101, bypassing downtown San Jose and instead passing through the foothill cities of Los Gatos, Saratoga, Cupertino, and other cities in the southern San Francisco Peninsula, roughly paralleling the Santa Cruz Mountains up to its interchange with I-280.
State Route 13 is a state highway in the U.S. state of California. It runs entirely in Alameda County, connecting Interstate 580 in Oakland to Interstate 80/Interstate 580 in Berkeley.
Route 238, consisting of State Route 238 (SR 238) and Interstate 238 (I-238), is a mostly north–south state and auxiliary Interstate highway in the San Francisco Bay Area of California. The southern segment is signed as SR 238 and is a divided multilane surface highway that runs parallel to the Hayward hills between I-680 in Fremont and I-580 in Castro Valley. The northern segment is signed as I-238 and is a six-lane freeway that runs more east–west between I-580 and I-880 in San Leandro.
State Route 92 is a state highway in the U.S. state of California, serving as a major east-west corridor in the San Francisco Bay Area. From its west end at State Route 1 in Half Moon Bay near the coast, it heads east across the San Francisco Peninsula and the San Mateo–Hayward Bridge to downtown Hayward in the East Bay at its junction with State Route 238 and State Route 185. It has interchanges with three freeways: Interstate 280, U.S. Route 101 in or near San Mateo, and Interstate 880 in Hayward. It also connects indirectly to Interstates 238 and 580 by way of Hayward's Foothill Boulevard, which carries Route 238 and flows directly into Route 92.
State Route 24 is a heavily traveled east–west state highway in the U.S. state of California that serves the eastern side of the San Francisco Bay Area. A freeway throughout its entire length, it runs from the Interstate 580/Interstate 980 interchange in Oakland, and through the Caldecott Tunnel under the Berkeley Hills, to the Interstate 680 junction in Walnut Creek. It lies in Alameda County, where it is highly urban, and Contra Costa County, where it passes through wooded hillsides and suburbs. SR 24 is a major connection between the San Francisco–Oakland Bay Bridge/MacArthur Maze complex and the inland cities of the East Bay.
State Route 237 is a state highway in the U.S. state of California that runs from El Camino Real in Mountain View to Interstate 680 in Milpitas. Known as the Southbay Freeway for most of its length, SR 237 runs south of the San Francisco Bay, connecting the East Bay to the Peninsula.
State Route 82 is a state highway in the U.S. state of California that runs from Interstate 880 (I-880) in San Jose to I-280 in San Francisco following the San Francisco Peninsula. It is the spinal arterial road of the peninsula and runs parallel to the nearby Caltrain line along much of the route. For much of its length, the highway is named El Camino Real and formed part of the historic El Camino Real mission trail. It passes through and near the historic downtowns of many Peninsula cities, including Burlingame, San Mateo, Redwood City, Menlo Park, Palo Alto, Mountain View, and Sunnyvale, and through some of the most walkable and transit-oriented neighborhoods in the region.
State Route 9 is a rural and mountainous state highway in the U.S. state of California that travels 35 miles (56 km) from SR 1 in Santa Cruz to SR 17 in Los Gatos, passing through the San Lorenzo Valley and the Saratoga Gap in the Santa Cruz Mountains.
State Route 84 is a state highway in the U.S. state of California that consists of two unconnected segments, one in the San Francisco Bay Area and the other primarily in the Sacramento–San Joaquin River Delta area.
The MacArthur Maze is a large freeway interchange near the east end of the San Francisco–Oakland Bay Bridge in Oakland, California. It splits Bay Bridge traffic into three freeways—the Eastshore (I-80/I-580), MacArthur (I-580) and Nimitz (I-880).
State Route 17 is a state highway in the U.S. state of California that runs from State Route 1 in Santa Cruz to I-280 and I-880 in San Jose. SR 17, a freeway and expressway, carries substantial commuter and vacation traffic through the Santa Cruz Mountains at Patchen Pass between Santa Cruz and the San Francisco Bay Area.
State Route 262 (SR 262) is a state highway entirely within the Warm Springs District of Fremont, California. It runs along the 1.07-mile (1.72 km) segment of Mission Boulevard between I-880 to the west and I-680 to the east. The route is heavily trafficked, going through a commercial district and containing at least two stop lights.
State Route 185 is a state highway in the San Francisco Bay Area of the U.S. state of California. It runs along sections of Mission Boulevard in Hayward, East 14th Street in San Leandro and International Boulevard in Oakland. At its south end, SR 185 connects with State Routes 92 and 238 in Hayward. At the north end of SR 185 at International Boulevard and 42nd Avenue, the short State Route 77 heads southwest to Interstate 880.
People in the San Francisco Bay Area rely on a complex multimodal transportation infrastructure consisting of roads, bridges, highways, rail, tunnels, airports, seaports, and bike and pedestrian paths. The development, maintenance, and operation of these different modes of transportation are overseen by various agencies, including the California Department of Transportation (Caltrans), the Association of Bay Area Governments, San Francisco Municipal Transportation Agency, and the Metropolitan Transportation Commission. These and other organizations collectively manage several interstate highways and state routes, two subway networks, two commuter rail agencies, eight trans-bay bridges, transbay ferry service, local bus service, three international airports, and an extensive network of roads, tunnels, and bike paths.
Interstate 80 (I-80) is a transcontinental Interstate Highway in the United States, stretching from San Francisco, California, to Teaneck, New Jersey. The segment of I-80 in California runs east from San Francisco across the San Francisco–Oakland Bay Bridge to Oakland, where it turns north and crosses the Carquinez Bridge before turning back northeast through the Sacramento Valley. I-80 then traverses the Sierra Nevada, cresting at Donner Summit, before crossing into the state of Nevada within the Truckee River Canyon. The speed limit is at most 65 mph (105 km/h) along the entire route instead of the state's maximum of 70 mph (110 km/h) as most of the route is in either urban areas or mountainous terrain. I-80 has portions designated as the Eastshore Freeway and Alan S. Hart Freeway.
The Cypress Street Viaduct, often referred to as the Cypress Structure or the Cypress Freeway, was a 1.6-mile-long (2.5 km), raised two-deck, multi-lane freeway constructed of reinforced concrete that was originally part of the Nimitz Freeway in Oakland, California.
If you use Bay Area Express Lanes, you must use a FasTrak toll tag, otherwise you will receive a violation notice including toll evasion penalties
Our main complaint with the Freeway is that it's so very short and runs you into dead ends at both 23rd avenue and at Sixth street so that the turn-off is hardly worth the bother.
