Interstate 580 (I-580) is an approximately 82-mile-long (132 km) east–west auxiliary Interstate Highway in Northern California. The heavily traveled spur route of I-80 runs from US 101 in San Rafael in the San Francisco Bay Area to I-5 near 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.
A portion of I-580 is called the MacArthur Freeway, after General Douglas MacArthur. Other portions are named the John T. Knox Freeway (after a former Speaker Pro Tempore of the California State Assembly), the Eastshore Freeway (after its location on San Francisco Bay), the Arthur H. Breed Jr. Freeway (after a former California State Assemblyman and Senator—the stretch itself lying between the cities of Castro Valley and Dublin), the William Elton "Brownie" Brown Freeway (after a Tracy resident instrumental in determining the route of Interstate 5 through the San Joaquin Valley), the Sgt. Daniel Sakai Memorial Highway (after the Castro Valley resident and Oakland SWAT officer killed in the 2009 shootings of Oakland police officers), and the John P. Miller Memorial Highway (after the Lodi resident and California Highway Patrol officer killed while chasing down a DUI driver).
The western terminus of I-580 is roughly 10 miles north of San Francisco in the city of San Rafael (Marin County), at the junction with U.S. Route 101 (US 101). The interchange with US 101 is incomplete, only allowing continuous travel from southbound US 101 to eastbound I-580 (via exit 451B) and from westbound I-580 to northbound US 101. Heading eastward through the light industrial portion of eastern San Rafael, I-580 provides access to San Quentin State Prison at the eastern tip of land before joining the Richmond–San Rafael Bridge to cross San Francisco Bay. I-580 enters the city of Richmond in Contra Costa County mid-span, then continues through Richmond to join Interstate 80 in Albany at the "Hoffman Split."
After joining I-80, I-580 runs directly south for several miles along the eastern shore of San Francisco Bay in the segment known as the Eastshore Freeway, then enters the MacArthur Maze. The segment between the Hoffman Split and the MacArthur Maze is a wrong-way concurrency, meaning I-580 east is signed as I-80 west, and vice versa. From the MacArthur Maze, I-580 is known as the MacArthur Freeway, which runs through Oakland and San Leandro to Castro Valley. About halfway to Castro Valley from the Maze, is an interchange with the Warren Freeway (State Route 13). Between this interchange and Castro Valley, I-580 runs near or along the trace of the Hayward Fault, a major branch of the San Andreas Fault.
In Castro Valley, I-580 turns eastward toward Dublin Canyon before descending into Dublin and Pleasanton. After passing through Livermore, the freeway enters the Altamont Pass. The road emerges in the Central Valley west of Tracy, where, after I-205 splits near the Altamont Speedway, it turns southeastward and terminates by merging with I-5 south of Tracy just shy of the Stanislaus County line.
I-580 through Altamont Pass is a major crossing of the Diablo Range linking the Central Valley to the Bay Area, and also a major route to Southern California. I-580 is the only freeway that crosses the Diablo Range, making it the safest route through the mountains. Prior to the construction of this route, traffic was detoured to Pacheco (SR 152) and Polonio (SR 46) passes.
I-580 provides Interstate Highway access between San Francisco and Los Angeles since I-5 runs east of the Bay Area. However, the primary control city listed on freeway signs along eastbound I-580 between I-80 and I-205 is instead Stockton, a vestige of when this segment used to be part of US 50.
I-580 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. The route is eligible for the State Scenic Highway System, and is officially designated as a scenic highway by the California Department of Transportation from the San Leandro city limits to SR 24 and from I-5 to I-205, meaning that these are substantial sections of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community.
Trucks over 4.5 tons are prohibited through Oakland between Grand Avenue and the San Leandro border. Specifically, eastbound trucks cannot travel beyond Grand Avenue/Lakeshore Avenue (exit 21B), and those going westbound must get off at MacArthur Boulevard/Foothill Boulevard (exit 30).They are instead instructed to take I-238 in Castro Valley and then I-880 through Oakland as an alternative route.
The truck prohibition has been in effect before the freeway was since the freeway was built in 1963 as part of US 50. Both the Federal Highway Administration (FHWA) and the California Department of Transportation (Caltrans) imposed the restriction, partly because the City of Oakland already had a truck ban through the area prior to the freeway's construction. Since then, the restriction was grandfathered in when the freeway was both renumbered and added to the Interstate Highway System.
As a result, it is the only segment of Interstate Highway in California that is not part of the National Truck Network (several other California state highways have similar truck bans such as SR 2, SR 13 and SR 85, but not any other Interstates).With trucks normally rerouted onto I-880 instead of I-580 through Oakland, the former generally gets more traffic than the latter. For decades, the trucking industry lobbied to have the ban removed, but was unsuccessful due to local opposition. In 2000, the California State Legislature passed Assembly Bill 500, adding the I-580 truck restriction into the California Vehicle Code. The ban is temporarily lifted by the California Highway Patrol for short periods to reduce traffic congestion when major accidents occur on I-880 or I-238.
High-occupancy toll (HOT) lanes along I-580 between Pleasanton and Livermore opened in February 2016. 12 miles (19 km) between Hacienda Drive and North Greenville Road. The westbound express lanes extend an additional two miles (3.2 km) west to San Ramon Road/Foothill Road.The eastbound express lanes stretch
As of October 2020 [update] , the HOT lanes' hours of operation is weekdays between 5 a.m. and 8 p.m. Solo drivers are tolled using a variable pricing system based on the time of day. Carpools, motorcycles, and clean air vehicles 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 either a FasTrak Flex or CAV (Clean Air Vehicle) transponder, with its switch set to indicate the number of the vehicle's occupants (1, 2, or 3 or more). Solo drivers may also use the FasTrak standard tag without the switch.
The high-occupancy vehicle (HOV) lane leading to the Richmond–San Rafael Bridge requires a car with 3+ persons, unlike California's regular carpool lanes of 2+ persons.
What is now I-580 from I-5 to Oakland was originally conceived as part of a loop Interstate with a directional suffix, I-5W. [ self-published source ] However, I-5W and most of the other Interstates around the country with directional suffixes were eventually renumbered or eliminated, except for I-35E and I-35W in Texas and Minnesota, and more recently Interstates 69W, 69C, and 69E in Texas. The former route of I-5W now corresponds to I-580 from I-5 to Oakland, I-80 from Oakland to Vacaville, and I-505 from Vacaville to I-5 near Dunnigan.
For the most part, the I-580 freeway in this segment was constructed over or alongside the right-of-way of US 50, previously part of the old Lincoln Highway, during the course of the late 1960s and early 1970s.[ citation needed ] The segment which begins at the split with I-205 was constructed during the same period of time over a new right-of-way to a junction with I-5, running through some low hills on the west side of the San Joaquin Valley near the city of Patterson.
In the 1990s, the freeway segment from Castro Valley through Pleasanton was enlarged and otherwise re-engineered in conjunction with the construction of the Dublin/Pleasanton Line of the Bay Area Rapid Transit. The BART tracks were placed in a new median between the westbound and eastbound lanes of I-580 as was the new Dublin/Pleasantion Station. The interchange with I-238 and the Hayward exit ramps was also re-engineered at this time.
The I-580 freeway in this segment was constructed starting in February 1960, adjacent to the city streets which were part of US 50 between Castro Valley and the large interchange along the eastern approach to the San Francisco–Oakland Bay Bridge in Oakland now called the MacArthur Maze. The freeway was named in honor of World War II General Douglas MacArthur. Prior to the construction of this freeway, the various city streets of Oakland that were designated for US 50 (principally 38th Street, Hopkins Street, Moss Avenue, Excelsior Avenue and part of Foothill Boulevard) had been re-named for the General as "MacArthur Boulevard" which, for the most part, still parallels the MacArthur Freeway. The re-naming occurred on March 26 1942, by a resolution of the Oakland City Council.
The freeway was opened to traffic in 8 segments until its completion in May, 1966 (last segment, connecting with State Route 238 (now I-238), in Castro Valley, opened May 20, 1966).
The segment of I-580 running from the MacArthur Maze to San Rafael is the most recent to be signed as I-580, beginning in 1984. Before 1984, this segment was part of State Route 17 (SR 17).
From the Maze to the interchange locally known as the "Hoffman Split" in Albany, just north of the Gilman Street interchange (Hoffman Blvd. was the predecessor of I-580 in this section---see below), I-580 follows the Eastshore Freeway, a wrong-way concurrency with I-80 for its entirety: northward on the Eastshore is signed I-80 east and I-580 west; headed southward, one finds signs indicating I-80 west and I-580 east.
At the Hoffman Split, I-580 leaves the Eastshore Freeway in a northwesterly direction through the cities of Albany and Richmond. It then crosses San Francisco Bay over the Richmond–San Rafael Bridge. The freeway in this section, officially named the John T. Knox Freeway, was constructed from 1987 to 1991. It replaced a number of city streets which comprised the earlier highway leading to the San Rafael Bridge, principally, Hoffman and Cutting Boulevards.
After crossing the bridge, I-580 runs west to San Rafael, ending at an interchange with US 101. This freeway segment supplanted an earlier boulevard constructed as part of SR 17.
|Location||San Rafael, California|
Interstate 180 was a temporary designation used in 1978 for the Richmond–San Rafael Bridge, now part of I-580. At the time the bridge had been identified as part of SR 17 but was marked for inclusion in the Interstate Highway System.
Briefly the bridge used the number 180, despite the Fresno-area SR 180's use of the number. The California Streets and Highways Code has a policy against using one route number for multiple noncontiguous highways. Unless the existing SR 180 is renumbered, which is unlikely due to its familiarity as the road to Kings Canyon National Park, there will not be an I-180 in California.
The segment of I-580 from I-680 to I-205 is undergoing significant expansion. Among the projects along this segment is the now-completed high-occupancy vehicle lanes in each direction, a westbound auxiliary lane between Fallon Road and Tassajara Road, the now-completed construction of a new interchange at Isabel Avenue in Livermore, the reconstruction of several interchanges, the construction of additional truck climbing lanes for the eastward ascent to the Altamont Pass, and plans to preserve the right-of-way to accommodate a future BART extension in the median of the freeway.

Interstate 5 (I-5) is the main north–south Interstate Highway on the West Coast of the United States, running largely parallel to the Pacific coast of the contiguous U.S. from Mexico to Canada. It travels through the states of California, Oregon, and Washington, serving several large cities on the U.S. West Coast, including San Diego, Los Angeles, Sacramento, Portland, and Seattle. It is the only continuous Interstate highway to touch both the Mexican and the Canadian borders. Upon crossing the Mexican border at its southern terminus, I-5 continues to Tijuana, Baja California, as Mexico Federal Highway 1 (Fed. 1). Upon crossing the Canadian border at its northern terminus, it continues to Vancouver as British Columbia Highway 99 (BC 99).
Interstate 238 (I-238) is an auxiliary Interstate Highway in the San Francisco Bay Area in the U.S. state of California. It comprises the northernmost 2.126 miles (3.421 km) of Route 238, as defined by the California Streets and Highways Code. Originally signed as State Route 238 (SR 238) until 1983, it connects I-580 in Castro Valley with I-880 in San Leandro.
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 Nimitz, who retired to the Bay Area. The northernmost five miles is also commonly referred to as the Cypress Freeway, after the former alignment of the freeway, and its subsequent replacement.
Interstate 980 (I-980) is a short 2.0-mile (3.2 km) auxiliary Interstate Highway spur entirely within the City of Oakland in Northern California, connecting Interstate 580 and State Route 24 to Interstate 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 San Francisco Bay 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 Interstate 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 57.5-mile-long (92.5 km) major north–south auxiliary Interstate Highway in the San Francisco Bay Area of Northern California. It runs from I-680 and US 101 in San Jose to King and Fifth 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.
State Route 238 is a north–south state highway in the U.S. state of California. The route is a divided multilane surface highway in the southeastern part of the San Francisco Bay Area. SR 238 connects Interstate 680 in Fremont with Interstate 580 in Castro Valley.
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 123 is a state highway in the U.S. state of California in the San Francisco Bay Area. Named San Pablo Avenue for virtually its entire length, SR 123 is a major north–south state highway along the flats of the urban East Bay. Route 123 runs about 7.39 miles (11.9 km) between Interstate 580 in Oakland in the south and Interstate 80 in Richmond in the north. San Pablo Avenue itself, a portion of Historic US 40, continues well past these termini, south to Downtown Oakland and north to Crockett, but without the Route 123 designation.
Interstate 205 (I-205) is an east–west auxiliary Interstate Highway in the San Joaquin Valley in Northern California. It runs from I-5 west to I-580. Along with those highways, I-205 forms the north side of a triangle around the city of Tracy. The route provides access from the San Francisco Bay Area to the northern San Joaquin Valley.
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 (SR 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 132 is a state highway in the U.S. state of California that connects the Central Valley with the Sierra Nevada foothills and the California Gold Country. Its western segment also connects the city of Modesto with the San Francisco Bay Area via I-580, although this route is discouraged due to it being a two-lane road between Modesto and Interstate 5 East of Modesto, the road climbs the foothills and eventually ends at SR 49 at Coulterville.
U.S. Route 101 (US 101) is a major north–south United States Numbered Highway, stretching from Los Angeles, California to Tumwater, Washington. The California portion of US 101 is one of the last remaining and longest U.S. Routes still active in the state, and the longest highway of any kind in California. US 101 was also one of the original national routes established in 1926. Significant portions of US 101 between the Los Angeles area and the San Francisco Bay Area follow El Camino Real, the commemorative route connecting the former Alta California's 21 missions.
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 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 miles per hour (105 km/h) along the entire route instead of the state's maximum of 70 mph (110 km/h) and 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.
Interstate 5 (I-5) is a major north–south route of the Interstate Highway System in the United States, stretching from the Mexican border at the San Ysidro crossing to the Canadian border near Blaine, Washington. From San Ysidro, the segment of I-5 in California runs north across the length of the state, and crosses into Oregon south of the Medford-Ashland metropolitan area. It is the more important and most-used of the two major north–south routes on the Pacific Coast, the other being U.S. Route 101 (US 101), which is primarily coastal. I-5 is known colloquially as "the 5" to Southern California residents and "5" to Northern California residents due to varieties in California English. The highway connects to the Mexican Federal Highway 1 (Fed. 1) in the south.
