Interstate 580 (I-580) is an 80-mile (129 km) east–west Interstate Highway in Northern California. The heavily traveled spur route of Interstate 80 runs from San Rafael in the San Francisco Bay Area to Interstate 5 near Tracy in the Central Valley. It provides access from San Francisco to the southern San Joaquin Valley and Southern California.

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 California State Assemblyman and Speaker Pro Tempore who currently practices law at Nossaman LLP), 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).[2]

This route is part of the California Freeway and Expressway System[5] and is eligible for the State Scenic Highway System.[6]

The western terminus of I-580 is north of San Francisco in San Rafael, at a junction with U.S. Route 101. The eastern terminus is with I-5 southeast of Tracy. Leaving San Rafael, I-580 runs next to the San Quentin State Prison before crossing San Francisco Bay over the Richmond-San Rafael Bridge. The road then passes through Richmond.

In Albany, I-580 joins I-80 and then turns east at the interchange known as the MacArthur Maze. From here, it 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 Interstate 205 splits near the Altamont Speedway, it turns southeastward and terminates by merging with Interstate 5 south of Tracy.

I-580 provides Interstate Highway access between San Francisco and Los Angeles since Interstate 5 runs east of the Bay Area. However, the primary control city listed on freeway signs along eastbound 580 between I-80 and I-205 is instead Stockton, a vestige of when this segment used to be part of U.S. Route 50.

Truck ban through Oakland[edit]

Trucks over 4.5 tons are prohibited through Oakland between Grand Avenue and the San Leandro border. Specifically, eastbound trucks cannot travel beyond the Grand Avenue/Lakeshore Avenue exit, and those going westbound must take the MacArthur Boulevard/Foothill Boulevard exit.[3][7] They are instead instructed to take Interstate 238 and Interstate 880 as an alternative route through Oakland.

The truck prohibition has been in effect since the freeway was built in 1963 as part of U.S. 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 one of the few segments along the Interstate Highway System that is not part of the National Truck Network. 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.[8] However, the California Highway Patrol has frequently allowed trucks through temporarily when major accidents occur on I-880 or I-238.

History[edit]

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.[9] However, I-5W and most of the other Interstates around the country with directional suffixes were eventually renumbered or eliminated, sans I-35E and I-35W in Texas and Minnesota. The former route of I-5W now corresponds to I-580 from I-5 to Oakland, I-80 from Oakland to Vacaville, and Interstate 505 from Vacaville to I-5 near Dunnigan.

I-5 to Castro Valley[edit]

For the most part, the I-580 freeway in this segment was constructed over or alongside the right-of-way of U.S. Route 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 MacArthur Freeway: Castro Valley to Oakland[edit]

The I-580 freeway in this segment was constructed in the 1960s adjacent to the city streets which were part of U.S. Route 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. Some years prior to the construction of this freeway, the various city streets of Oakland (principally 38th Street, Hopkins Street, and part of Foothill Blvd.) had been named for the General as "MacArthur Boulevard" which, for the most part, still parallels the MacArthur Freeway.

Oakland to San Rafael[edit]

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.

From the Maze to the interchange locally known as the "Hoffman Split" in Albany, just north of the Gilman Street interchange, 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 El Cerrito 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 U.S. Route 101. This freeway segment supplanted an earlier boulevard constructed as part of State Route 17.

Interstate 180[edit]

Interstate 180 was a temporary designation used in 1978 for the Richmond-San Rafael Bridge, now part of Interstate 580. At the time the bridge had been identified as part of State Route 17 but was marked for inclusion in the Interstate Highway System.

Briefly the bridge used the number 180, despite the Fresno-area State Route 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 Route 180 is renumbered, which is unlikely due to its familiarity as the road to Kings Canyon National Park, there will not be an Interstate 180 in California.

Future[edit]

The segment of I-580 from I-680 to I-205 is undergoing significant expansion. Among the projects along this segment is the construction of high-occupancy vehicle lanes in each direction, a westbound auxiliary lane between Fallon Road and Tassajara Road, the 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.[10]

There is a plan to add high-occupancy toll (HOT) lanes along I-580 between Pleasanton and Livermore.[11] Under the plan, the 12-mile (19 km) stretch between Hacienda Drive and North Greenville Road would be modified to include HOT lanes. They are scheduled to open in 2015.[11] Solo drivers would then be required to use a FasTrak transponder.

Exit list[edit]

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on a south-to-north alignment (as originally conceived as part of I-5W, as well as the segment that was formerly part of State Route 17), and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see the list of postmile definitions).[4] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
