42-769: The park is centered on the Miller/Knox lagoon which is depicted on a large 200 foot by 50 foot mural at the Richmond Municipal Natatorium nearby. The park affords panoramic views of the Bay Area especially the Oakland and San Francisco skylines, islands, bridges, and the North Bay mountains. The views are the farthest from the park's high point: Nicholls Knob. The regional shoreline includes Keller Beach on San Pablo Bay in addition to large picnic and barbecue areas, parking and

84-689: A calendar of community events to recruit workers and raise funds. Architect Todd Jersey of Todd Jersey Architecture in Berkeley donated hundreds of hours to the Plunge restoration project, with the hopes of making the Plunge the most environmentally friendly public pool in the country. Jersey raised a portion of the roof to add windows, improving ventilation and light. Overall, the building has more than 170 windows, 132 of which will be able to open and close. The first phase of reconstruction began in August 2008. The Plunge

126-539: A fishing pier. There is also a former train ferry pier at Ferry Point and other assorted ruins. The park is also home to the Golden State Model Railroad Museum . The park is named for former state senator George Miller, Jr. and former State Assembly member and Point Richmond resident John T. Knox . The park features many trails for cyclists, dog-walkers, and hikers, and a salt water lagoon where ducks, seagulls, and Canada Geese frolic. The beach

168-651: A loop Interstate with a directional suffix and was what is now I-580 from I-5 to Oakland. 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 in Texas, the designations of I-69W , I-69C , and I-69E , along with proposed suffixed segments for future extensions of I-14 and I-27 . 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

210-647: 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

252-470: Is a historic swim center in the Point Richmond neighborhood of Richmond, California . It was closed in August 2001 for seismic retrofitting and reopened in August 2010. It now is back to a regular schedule. Promoted by the citizens of Richmond, The Plunge was created through a bond issue in 1926. At that time, it was a "state of the art" two-story building with an indoor warm water swimming pool double

294-586: Is accessible from Interstate 580 and AC Transit line 72M Macdonald. Interstate 580 (California) 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

336-680: 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 (FHWA). The route is eligible for the State Scenic Highway System and

378-610: Is officially designated as a scenic highway by the California Department of Transportation (Caltrans) 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 short tons (4.1 t; 4.0 long tons) are prohibited through Oakland between Grand Avenue and

420-484: 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. Drivers without any FasTrak tag will be assessed a toll violation regardless of whether they qualified for free. Interstate 5W ( I-5W ) was originally conceived as part of

462-508: 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

504-548: The Hayward exit ramps was also reengineered at this time. Significant expansion to the segment between I-680 and I-205 began in 2006. Among the projects along this segment were the high-occupancy vehicle lanes in each direction, a westbound auxiliary lane between Fallon and Tassajara roads, a new interchange at Isabel Avenue in Livermore, the reconstruction of several interchanges, the construction of additional truck climbing lanes for

546-585: 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 (16 km) north of San Francisco in the city of San Rafael ( Marin County ), at the junction with 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. Traffic headed

588-660: 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 SR 17 . From the Maze to the interchange locally known as the "Hoffman Split" in Albany , just north of the Gilman Street interchange (Hoffman Boulevard was the predecessor of I-580 in this section), I-580 follows the Eastshore Freeway , a wrong-way concurrency with I-80 for its entirety: northward on

630-611: The San Joaquin Valley near the city of Patterson . In the 1990s, the freeway segment from Castro Valley through Pleasanton was enlarged and otherwise reengineered in conjunction with the construction of the Blue Line of the Bay Area Rapid Transit (BART). The BART tracks were placed in a new median between the westbound and eastbound lanes of I-580 as was the new Dublin/Pleasanton station . The interchange with I-238 and

672-520: 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

714-719: 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 assemblyperson and senator—the stretch itself lying between

756-627: 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,

798-689: The General as "MacArthur Boulevard" which, for the most part, still parallels the MacArthur Freeway. The renaming occurred on March 26, 1942, by a resolution of the Oakland City Council . The freeway was opened to traffic in eight segments until its completion in May 1966 (last segment, connecting with SR 238 (now I-238 ), in Castro Valley, opened May 20, 1966). The segment of I-580 running from

840-446: 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. 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

882-716: 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 ,

924-804: The Plunge. The renovation planning process was complicated by the fact that the Plunge is located in the Point Richmond Historic District , which is on the National Register of Historic Places . This meant that officials had to ensure the renovation would not damage the site's historic value. Richmond Friends of Recreation established a "Save the Richmond Plunge Trust" under its tax-exempt status and raised over $ 154,000 in cash and in excess of $ 40,000 in kind donations from local business owners. It committed to an ambitious campaign of appeals to corporations, foundations, and individuals and

966-457: 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 California Highway Patrol may however temporarily lift

1008-452: The ban for short periods to reduce traffic congestion when major accidents occur on I-880 or I-238. The truck prohibition has been in effect since before the freeway was built in 1963 as part of US 50. Both the FHWA and 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

1050-592: The ban. He did however concede that the California State Legislature would have to eventually repeal the aforementioned rule in the California Vehicle Code for any change to occur. Tolls are collected only for westbound traffic on the Richmond–San Rafael Bridge . An open road tolling system is used on the bridge, and they can be paid by either a FasTrak transponder or license plate tolling . The high-occupancy vehicle (HOV) lane leading to

1092-464: The bridge requires a car with three or more people. High-occupancy toll (HOT) lanes along I-580 between Pleasanton and Livermore opened in February 2016. The eastbound express lanes stretch 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. As of August 2022 ,

1134-483: The building and determined they had no option but to close the Plunge permanently. However, even though it was unsafe, people were allowed to swim in it until August 2001, although they had to pass "Swim at your own risk" signs. When the Plunge was slated for demolition, residents protested and RFR stepped in to work with the City in a unique Public/Private Partnership to raise the necessary funds to retrofit, upgrade and reopen

1176-505: The cities of Castro Valley and Dublin ), the William Elton "Brownie" Brown Freeway (after a Tracy resident instrumental in determining the route of I-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

1218-583: 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 renamed for

1260-597: 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. In 2017, citing lack of interest from the Bay Area Rapid Transit District in bringing BART service east to Livermore, the Livermore City Council proposed a newly established local entity to undertake planning and construction of the extension, which

1302-1043: 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. A collaborative study by the Environmental Defense Fund , Google , and the University of Texas at Austin used Google Street View cars equipped with air quality monitors to measure pollution data through Oakland. It found that along I-880, concentrations of black carbon were 80 percent higher, concentrations of nitrogen dioxide were 60 percent higher, and concentrations of nitric oxide were at least double than those along I-580. This has led community leaders to revisit

1344-665: The freeway enters the Altamont Pass . The road emerges in the Central Valley west of Tracy , where, after I-205 splits near Altamont Raceway Park , 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

1386-414: 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. 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

1428-600: The other two directions is encouraged to use Sir Francis Drake Blvd . 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 midspan, then continues through Richmond to join I-80 in Albany at

1470-530: The size of an Olympic pool, a fountain, observation balconies, and an open truss ceiling reminiscent of the Sutro Baths in San Francisco. Richmond's population was about 20,000 then, grew to over 200,000 during the "war years" and is now about 110,000. Over the years, the masonry building deteriorated, the hollow-clay-tile walls cracking after 76 years of deferred maintenance. Richmond Friends of Recreation (RFR)

1512-502: The truck ban, particularly because I-880 runs along minority communities while I-580 runs through middle and upper middle class neighborhoods. Once a proponent of the ban when he served on the Oakland City Council in the 1990s, Alameda County Supervisor Nate Miley held a December 2021 virtual town hall on the issue, and asked both Caltrans and the Bay Area Air Quality Management District to conduct studies on

1554-626: 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 and SR 85 , but not any other Interstates). With trucks normally rerouted onto I-880 instead of I-580 through Oakland,

1596-576: 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

1638-614: Was also recommended by the California State Assembly Transportation Committee. Assembly Bill 758 was signed by then- Governor of California Jerry Brown on October 13, 2017, formally establishing the Tri-Valley–San Joaquin Valley Regional Rail Authority to construct and maintain the alternative Valley Link commuter rail. The I-580 freeway in this segment was constructed starting in February 1960, adjacent to

1722-475: 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.

1764-471: Was organized in 1979 as a non-profit organization with the purpose of supporting community recreation programs, spearheaded a major rehabilitation of the pool equipment and repainting of the structure. The Plunge was further damaged in the 1989 Loma Prieta earthquake . City voters rejected a bond measure to reinforce it in 1997. In November 1997, the City Council realized they did not have the funds to retrofit
