Interstate 580 (abbreviated I-580) in Northern California is a heavily traveled, 80-mile (129 km) long spur route of Interstate 80 that connects the San Francisco Bay Area to Interstate 5 in the state's Central Valley. A portion of I-580 is called the MacArthur Freeway.

[edit] Route description

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. It was named after General Douglas MacArthur in 1968. 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 Point Richmond and follows a right-of-way formerly named Hoffman Boulevard, once designated Route 17. In Albany I-580 joins I-80 and then splits five miles later in Oakland. The route roughly parallels Macarthur Boulevard, formerly the route of 580's predecessor US 50, toward San Leandro and in Castro Valley turns eastward toward Dublin Canyon. 580 descends into Dublin and Pleasanton, and then after Livermore it enters the Altamont Pass. The road emerges in the Central Valley near Tracy, where, after I-205 splits near the Altamont Speedway, it turns southeastward and terminates by merging with Interstate 5 near Patterson.

[edit] History

Much of I-580, from near Tracy to Oakland, follows the general alignment of the transcontinental Lincoln Highway, later U.S. Route 50 in that area. This (and other roads) had been defined as Legislative Route 5 in 1909, forming a two-pronged route from Stockton west over Altamont Pass to Hayward, where it split towards Santa Cruz and Oakland:^[4][5]

• State Route 17 from Santa Cruz to San Jose
• Oakland Road, Main Street, Milpitas Boulevard and Warm Springs Boulevard (replaced by Interstate 680) from San Jose to Warm Springs
• State Route 262, Mission Boulevard and State Route 238 from Warm Springs to near Hayward (SR 262 west to Interstate 880 was a spur of pre-1964 Legislative Route 69, now I-880)
• Present I-580 and Interstate 80 from near Hayward to the east end of the San Francisco-Oakland Bay Bridge
• Present I-580, Interstate 205 and Interstate 5 (along El Dorado Street) from Hayward to Stockton, where it turned east on State Route 4 to end at pre-1964 Legislative Route 4 (State Route 99).
• In 1933, an extension was added from Stockton east to present State Route 49 at Mokelumne Hill, and it was further extended to present State Route 104 at West Point in 1963. This is now State Route 26.

For details on the sections that are not I-580, see the articles on State Route 17, Interstate 680, State Route 262, Mission Boulevard, State Route 238, Interstate 205 and State Route 26. For detailed history of the I-580 section, see Lincoln Highway in California.

The Lincoln Highway was designated in late 1913 along this road from Jack London Square in downtown Oakland via Hayward to French Camp (south of Stockton), the original end of Route 5, where it ran north on Route 4 to Sacramento. In late 1926, U.S. Route 48 was designated along the part of Route 5 from San Jose via Hayward to French Camp, ending at U.S. Route 101 in San Jose and U.S. Route 99 at French Camp. (The route was not marked until 1928.) The San Jose-Hayward section of Route 5 was designated as U.S. Route 101E ca. 1929, as was the Hayward-Oakland section, truncating US 48 at Hayward. Also around that time, Route 4 was relocated to the east of French Camp, and Route 5 was extended northeast to Stockton.

Around 1931, US 48 became part of a western extension of U.S. Route 50, running south on Route 4 from Sacramento to Stockton and then west on Route 5 via Hayward to Oakland.

Route 5 from Oakland to west of Tracy and present I-580 and State Route 132 to Modesto (pre-1964 Legislative Route 110) was added to the planned Interstate Highway System on August 7, 1947. In May 1957, the planned I-5 was moved west from Route 99 to its present alignment, and I-580 was truncated to I-5 east of Tracy. Interstate 205 was added on November 8, 1957.

The number Interstate 5W was applied to present I-580, as well as present Interstate 505, on August 14, 1957. It kept this number until July 1, 1964, when California executed its 1964 renumbering.^[2] Route 5, and all other pre-1964 legislative routes, were replaced with existing or new signed numbers, including I-580 from south of Tracy to Oakland. I-580 had been signed as U.S. Route 50 west of the I-205 split near Tracy; this was truncated to Sacramento.

In April 1978, Interstate 180 was assigned to the spur from Interstate 80 in Albany northwest and west over the Richmond-San Rafael Bridge to U.S. Route 101 in San Rafael. This was signed as State Route 17, and in 1984 it was transferred to an extension of I-580 (number approved by AASHTO in June 1983 because of conflicts with State Route 180). Construction on this section, named the John T. Knox Freeway, was begun in 1987 and completed in 1991^[6] This segment was signed as "Temporary I-580" from 1984 until construction of the freeway I-580 was completed.^[7]

[edit] Truck ban through Oakland

Trucks over 4.5 tons are prohibited through Oakland between Grand Avenue and the San Leandro border. Instead, they are instructed to take Interstate 880 and Interstate 238.^[8]

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.

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.^[9] However, the California Highway Patrol has frequently allowed trucks through temporarily when major accidents occur on I-880 or I-238.

[edit] Control cities

Eastbound

• Richmond Bridge - between US 101 and the aforementioned bridge
• Oakland - between US 101 and I-80
• Hayward - between I-80 and the I-238/SR-238 interchange
• Stockton - between I-80 and I-205
• Fresno - between Livermore and I-5
• Los Angeles - between I-205 and I-5

[edit] Major cities/towns along route

• San Rafael
• Richmond
• Albany
• Berkeley
• Emeryville
• Oakland
• San Leandro
• Castro Valley
• Dublin
• Pleasanton
• Livermore
• Tracy

[edit] Intersections with other interstates

• Joins Interstate 80 in Albany.
• Separates from I-80 in Emeryville (junction is also the north terminus of Interstate 880).
• Interstate 980 (northern terminus of I-980) in Oakland. This intersection is known as the MacArthur Maze.
• Interstate 238 (southern terminus of I-238) in Castro Valley. I-238 runs almost exactly east-west, though is signed as a north-south route; the intersection with I-238 is at the easternmost part of I-238.
• Interstate 680 in Pleasanton.
• Interstate 205 (western terminus of I-205) between Livermore and Tracy.
• Interstate 5 near Patterson.

[edit] Notes

• On the section of 10-lane freeway that is designated both I-80 and I-580, from Emeryville to Albany, the two routes are labeled with opposite directions – that is, while a vehicle is physically moving north on the road, it is on both I-80 East and I-580 West.
• The Dublin/Pleasanton Line of the Bay Area Rapid Transit runs in the freeway's center median between the Interstate 238 interchange and the Dublin/Pleasanton Station.
• The portion of I-580 between Highways 13 and 238 runs very close to the Hayward Fault Zone, and crosses it 4 times.

[edit] State law

Legal definition of Route 580: California Streets and Highways Code, Chapter 2, Article 3, Section 618

Route 580 is part of the Scenic Highway System, as stated by section 263.1 of the California State Highway Code.

[edit] Exit list

Postmiles are derived from^[1]and exit numbers derived from^[10].

Note that postmiles increase from east to west, the reverse of the exit numbers. This is because Interstate 580 assimilated much of what was Highway 17 and Interstate 5W, both south-north highways.
