'''Interstate&nbsp;580''' ('''I-580''') is an approximately {{convert|76|mi|km|adj=mid|-long}} east–west [[auxiliary Interstate Highway]] in [[Northern California]]. The heavily traveled [[spur route]] of [[Interstate 80 in California|I-80]] runs from [[U.S. Route 101 in California|US Route&nbsp;101]] (US&nbsp;101) in [[San Rafael, California|San Rafael]] in the [[San Francisco Bay Area]] to [[Interstate 5 in California|I-5]] at a point outside the southern city limits of [[Tracy, California|Tracy]] in the [[Central Valley (California)|Central Valley]]. I-580 forms a [[concurrency (road)|concurrency]] with I-80 between [[Albany, California|Albany]] and [[Oakland, California|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 [[John T. Knox|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 the cities of [[Castro Valley, California|Castro Valley]] and [[Dublin, California|Dublin]]), the '''William Elton "Brownie" Brown Freeway''' (after a [[Tracy, California|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 the [[Lodi, California|Lodi]] resident and [[California Highway Patrol]] officer killed while chasing down a [[DUI]] driver).<ref name="faigin"/>

<!-- Route descriptions should be written in a present-day perspective. Any changes or significant events may be indicated in the History section. -->

The entirety of I-580 is defined in section 618 of the [[California Codes|California Streets and Highways Code]] as '''Route 580''':<ref name="CSHC618">{{Cite web |url = https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=SHC&sectionNum=618. |title = Section 618 |work = California Streets and Highways Code |publisher = California Office of Legislative Counsel |location = Sacramento |access-date = August 17, 2025 }}</ref>

<blockquote>
Route 580 is from:
<br />(a) [[Interstate 5 in California|Route 5]] southwest of [[Vernalis, California|Vernalis]] to [[Interstate 80 in California|Route 80]] in [[Oakland, California|Oakland]] via the vicinity of [[Dublin, California|Dublin]] and [[Hayward, California|Hayward]].
<br />(b) Route 80 near [[Albany, California|Albany]] to [[U.S. Route 101 in California|Route 101]] near [[San Rafael, California|San Rafael]] via the [[Richmond–San Rafael Bridge|Richmond-San Rafael Bridge]].
</blockquote>

The definition omits Route 580's [[Concurrency (road)|concurrency]] with Route 80 instead of duplicating that segment in the other route's definition in the code. The overlapped segment with I-80 is also not included in the [[Federal Highway Administration]] (FHWA)'s route logs of I-580,<ref name="FHWA">{{cite web |title = Table 1: Auxiliary Routes of the Dwight D. Eisenhower National System Of Interstate and Defense Highways |url = https://www.fhwa.dot.gov/planning/national_highway_system/interstate_highway_system/routefinder/table02.cfm |work = FHWA Route Log and Finder List |publisher = [[Federal Highway Administration]] |date = January 2025 |access-date = August 17, 2025 }}</ref> but is still signed as such by Caltrans.

The western terminus of I-580 is roughly {{Convert|10|mi|km}} north of [[San Francisco]] in the city of [[San Rafael, California|San Rafael]] ([[Marin County, California|Marin County]]), at the junction with [[U.S. Route 101 in California|US&nbsp;101]]. The interchange with US&nbsp;101 is incomplete, only allowing continuous travel from southbound US&nbsp;101 to eastbound I-580 (via exit&nbsp;451B) and from westbound I-580 to northbound US&nbsp;101. Traffic headed the other two directions is encouraged to use [[Sir Francis Drake Boulevard]].  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, California|Richmond]] in [[Contra Costa County, California|Contra Costa County]] midspan, then continues through Richmond to join [[Interstate 80 in California|I-80]] in [[Albany, California|Albany]] in [[Alameda County, California|Alameda County]] 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, California|Oakland]] and [[San Leandro, California|San Leandro]] to [[Castro Valley, California|Castro Valley]]. About halfway to Castro Valley from the Maze, is an interchange with the [[Warren Freeway]] ([[California State Route 13|State Route&nbsp;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, California|Dublin]] and [[Pleasanton, California|Pleasanton]]. After passing through [[Livermore, California|Livermore]], the freeway enters the [[Altamont Pass]]. The road emerges in the Central Valley west of [[Tracy, California|Tracy]], where, after [[Interstate 205 (California)|I-205]] splits near [[Altamont Raceway Park]], it turns southeastward into [[San Joaquin County, California|San Joaquin County]] and terminates by merging with [[Interstate 5 in California|I-5]] south of Tracy just shy of the [[Stanislaus County, California|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 Pass|Pacheco]] ([[California State Route 152|SR&nbsp;152]]) and [[Polonio Pass|Polonio]] ([[California State Route 46|SR&nbsp;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, California|Stockton]], a vestige of when this segment used to be part of [[U.S. Route 50 in California|US&nbsp;50]].

I-580 is part of the [[California Freeway and Expressway System]]<ref name="cafes">{{CAFESystem}}</ref> and is part of the [[National Highway System (United States)|National Highway System]],<ref name=fhwa-nhs>{{FHWA NHS map |region = sanfrancisco |access-date = July 29, 2017 }}<br />{{FHWA NHS map |region = californianorth |access-date = July 29, 2017 }}</ref> a network of highways that are considered essential to the country's economy, defense, and mobility by the [[Federal Highway Administration]] (FHWA).<ref name=NHS-FHWA>{{FHWA NHS}}</ref> The route is eligible for the [[State Scenic Highway System (California)|State Scenic Highway System]]<ref name="scenic">{{CA scenic}}</ref> and is officially designated as a scenic highway by the [[California Department of Transportation]] (Caltrans) from the [[San Leandro, California|San Leandro]] city limits to [[California State Route 24|SR&nbsp;24]] and from I-5 to I-205,<ref name="caltransscenic">{{Caltrans scenic |access-date = July 29, 2017 }}</ref> 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.<ref>{{Caltrans scenic info}}</ref>

==Truck ban through Oakland==
Trucks over {{Convert|4.5|ST|t LT}} are prohibited through Oakland between Grand Avenue and the San Leandro border. Specifically, eastbound trucks cannot travel beyond Grand Avenue/Lakeshore Avenue (exit&nbsp;21B), and those going westbound must get off at MacArthur Boulevard/Foothill Boulevard (exit&nbsp;30).<ref name="truckhistory">{{cite web |url = https://dot.ca.gov/programs/traffic-operations/legal-truck-access/restrict-route-580 |title = Special Route Restriction History: Route 580 |publisher = California Department of Transportation |access-date = April 12, 2021 |archive-date = April 12, 2021 |archive-url = https://web.archive.org/web/20210412182458/https://dot.ca.gov/programs/traffic-operations/legal-truck-access/restrict-route-580 |url-status = live }}</ref><ref name=bridgelog>{{Caltrans bridgelog |date = July 2007 }}</ref> They are instead instructed to take [[Interstate 238|I-238]] in Castro Valley and then [[Interstate 880 (California)|I-880]] through Oakland as an alternative route.<ref>{{cite web |title = 'Oakland trucks use I-880' sign along westbound I-580 before the I-238 exit |url = https://www.google.com/maps/@37.6908834,-122.086806,3a,75y,299.31h,97.53t/data=!3m6!1e1!3m4!1sMUBkQgsEsIJq2TqoHr7Sww!2e0!7i16384!8i8192 |work = Google Street View |date = November 2022 |access-date = February 4, 2023 }}</ref><ref>{{cite web |title = 'Los Angeles: use I-580, trucks use I-880' sign along eastbound I-80 before the MacArthur Maze |url = https://www.google.com/maps/@37.8222443,-122.3230811,3a,75y,125.11h,98.74t/data=!3m6!1e1!3m4!1sGkKa2xwY6_PeBcTDFPrzJQ!2e0!7i16384!8i8192 |work = Google Street View |date = October 2022 |access-date = February 4, 2023 }}</ref> The [[California Highway Patrol]] may however temporarily lift 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&nbsp;50. Both the [[Federal Highway Administration|FHWA]] and [[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]].<ref name="truckhistory"/><ref name="KQED">{{cite web |first = Laura |last = Kilvans |url = https://www.kqed.org/news/11879641/trucks-are-banned-on-oaklands-i-580-these-sixth-graders-wondered-why |title = Trucks are Banned on Oakland's I-580.

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 [[California State Route 2|SR&nbsp;2]] and [[California State Route 85|SR&nbsp;85]], but not any other Interstates).<ref name="truckhistory"/><ref>{{cite web |url = http://www.dot.ca.gov/hq/traffops/trucks/routes/restrict-list.htm |title = Special Route Restrictions |publisher = California Department of Transportation |access-date = October 2, 2015 |archive-date = September 5, 2015 |archive-url = https://web.archive.org/web/20150905054421/http://www.dot.ca.gov/hq/traffops/trucks/routes/restrict-list.htm |url-status = live }}</ref> 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&nbsp;500, adding the I-580 truck restriction into the California Vehicle Code.<ref>{{cite web |author = Corbett |url = http://leginfo.ca.gov/pub/99-00/bill/asm/ab_0451-0500/ab_500_bill_20000810_chaptered.html |title = California Assembly Bill 500 |publisher = Leginfo.ca.gov |access-date = January 26, 2013 |archive-date = October 24, 2012 |archive-url = https://web.archive.org/web/20121024030943/http://www.leginfo.ca.gov/pub/99-00/bill/asm/ab_0451-0500/ab_500_bill_20000810_chaptered.html |url-status = live }}</ref>

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.<ref name="KQED"/> This has led community leaders to revisit 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,<ref name="KQED"/> [[Alameda County Board of Supervisors|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 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.<ref>{{cite web |url = https://abc7news.com/580-truck-ban-air-quality-bay-area-pollution-880/11350846/ |title = Calls grow to reconsider I-580 truck ban due to impact on minority communities along I-880 |website = KGO-TV |date = December 17, 2021 |access-date = November 4, 2025 }}</ref>

In 2025, Caltrans began to conduct its study on the truck ban and the impact on safety, pollution, and traffic, which is expected to be concluded in 2026.<ref>{{cite web |first = Laura |last = Kilvans |url = https://www.kqed.org/news/12032217/caltrans-launches-long-awaited-study-on-i-580-truck-ban-and-pollution-impact |title = Caltrans Launches Long-Awaited Study on I-580 Truck Ban and Pollution Impact |location = San Francisco |publisher = KQED-TV |date = March 23, 2025 |access-date = November 4, 2025 }}</ref> Supporters of lifting the ban continue to argue that it overburdens the minority communities along I-880; supporters of keeping the ban note that there are more schools and community sites along I-580, and argue that lifting the ban would just spread the pollution around the city and the Bay Area.<ref>{{cite web |first = Laura |last = Kilvans |url = https://www.kqed.org/science/1998844/caltrans-barrels-ahead-with-study-of-east-bay-truck-ban |title = Caltrans Barrels Ahead With Study of East Bay Truck Ban |location = San Francisco |publisher = KQED-TV |date = October 16, 2025 |access-date = November 4, 2025 }}</ref>

== Tolls ==
===Richmond–San Rafael Bridge===
{{Main|Richmond–San Rafael Bridge#Tolls}}
Tolls are collected only for westbound traffic on the [[Richmond–San Rafael Bridge]] headed to San Rafael. [[All-electronic tolling]] 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 the bridge requires a car with three or more people.<ref>{{cite web |title = Richmond–San Rafael Bridge |url = https://www.bayareafastrak.org/en/tolls/richmond-san-rafael-bridge.shtml |website = BayAreaFastrak.org |publisher = California Department of Transportation |access-date = August 14, 2022 |archive-date = August 7, 2022 |archive-url = https://web.archive.org/web/20220807064204/https://www.bayareafastrak.org/en/tolls/richmond-san-rafael-bridge.shtml |url-status = live }}</ref><ref>{{cite web |title = High-Occupancy Vehicle (HOV) & Express Lanes Northern California Region |url = http://www.dot.ca.gov/hq/traffops/trafmgmt/hov/files/HOV_NorCal.pdf |publisher = California Department of Transportation |access-date = June 2, 2016 |archive-date = July 1, 2016 |archive-url = https://web.archive.org/web/20160701200253/http://www.dot.ca.gov/hq/traffops/trafmgmt/hov/files/HOV_NorCal.pdf |url-status = live }}</ref>

'''Interstate&nbsp;5W''' ('''I-5W''') was originally conceived as part of a loop Interstate with a directional suffix and was what is now I-580 from I-5 to Oakland.<ref name="cahighways_5">{{cite web |first = Daniel P. |last = Faigin |date = August 6, 2022 |url = http://cahighways.org/001-008.html#005 |title = Interstate 5 |work = California Highways |access-date = September 7, 2022 |archive-date = April 22, 2022 |archive-url = https://web.archive.org/web/20220422023917/https://www.cahighways.org/001-008.html#005 |url-status = live }}{{sps|certain=yes|date=September 2022}}</ref>{{self-published inline|certain=y|date=June 2016}} However, I-5W and most of the other Interstates around the country with directional suffixes were eventually renumbered or eliminated, except for [[Interstate 35E (disambiguation)|I-35E]] and [[Interstate 35W (disambiguation)|I-35W]] in Texas and Minnesota, and more recently in Texas, the designations of [[Interstate 69W|I-69W]], [[Interstate 69C|I-69C]], and [[Interstate 69E|I-69E]], along with proposed suffixed segments for future extensions of [[Interstate 14#Proposed extension|I-14]] and [[Interstate 27#Numbering|I-27]]. The former route of I-5W now corresponds to I-580 from I-5 to Oakland, I-80 from Oakland to [[Vacaville, California|Vacaville]], and [[Interstate 505|I-505]] from Vacaville to I-5 near Dunnigan.

===I-5 to Castro Valley===
For the most part, the I-580 freeway in this segment was constructed over or alongside the [[Right-of-way (transportation)|right-of-way]] of [[U.S. Route 50 in California|US&nbsp;50]], previously part of the old [[Lincoln Highway]], during the course of the late 1960s and early 1970s.{{citation needed|date=December 2014}} <!-- The dates of construction should be checked --> The segment which begins at the split with I-205 was constructed during the same period of time over a new right-of-way, running through some low hills on the west side of the [[San Joaquin Valley]] near the city of [[Patterson, California|Patterson]] to a junction with I-5.

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 (BART)|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 [[Interstate 238|I-238]] and the [[Hayward, California|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 lane]]s 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 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.<ref>{{cite web |url = http://www.i580.info/projects/projects.php |title = I-580 Corridor Improvements: Project List |date = 2006 |author1 = Alameda County Congestion Management Agency |author2 = California Department of Transportation |publisher = Alameda County Congestion Management Agency |access-date = March 2, 2009 |url-status = dead |archive-url = https://web.archive.org/web/20070111030644/http://www.i580.info/projects/projects.php |archive-date = January 11, 2007 }}</ref> 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,<ref>{{cite news |last1 = Angela Ruggiero |first1 = Angela Ruggiero |title = Livermore says BART board doesn't care, wants local control |url = http://www.timesheraldonline.com/article/NH/20170411/SPORTS/170419966 |access-date = May 23, 2017 |agency = Vallejo Times-Herald |date = April 11, 2017 }}</ref> which was also recommended by the California State Assembly Transportation Committee.<ref>{{cite news |last1 = Matthews |first1 = Sam |title = Closer to a BART connection |url = http://www.goldenstatenewspapers.com/tracy_press/news/closer-to-a-bart-connection/article_5d034ce6-2bad-11e7-bfba-7ba7e05fa8d0.html |access-date = June 2, 2017 |agency = Tracy Press |date = April 28, 2017 }}</ref> Assembly Bill 758 was signed by then-[[Governor of California]] [[Jerry Brown]] on October&nbsp;13, 2017, formally establishing the Tri-Valley–San Joaquin Valley Regional Rail Authority to construct and maintain the alternative [[Valley Link]] commuter rail.<ref name=AB758>{{cite web |title = AB-758 Transportation: Tri-Valley–San Joaquin Valley Regional Rail Authority. |url = https://leginfo.legislature.ca.gov/faces/billTextClient.xhtml?bill_id=201720180AB758 |access-date = October 17, 2017 }}</ref>

===MacArthur Freeway: Castro Valley to Oakland===
The I-580 freeway in this segment was constructed starting in February 1960, adjacent to the city streets which were part of US&nbsp;50 between [[Castro Valley, California|Castro Valley]] and the large interchange along the eastern approach to the [[San Francisco–Oakland Bay Bridge]] in [[Oakland, California|Oakland]] now called the [[MacArthur Maze]].<ref>{{cite magazine |first = L.M. |last = Peterson |url = https://archive.org/details/cavol3940liforniahigh6061wa00calirich/page/n89 |title = US&nbsp;50 Freeway: State Begins Construction on MacArthur Freeway in Oakland |magazine = California Highways and Public Works |volume = 39 |issue = 3–4 |date = March–April 1960 |page = 8 |issn = 0008-1159 |via = [[Internet Archive]] }}</ref> The freeway was named in honor of World War&nbsp;II General [[Douglas MacArthur]]. Prior to the construction of this freeway, the various city streets of Oakland that were designated for US&nbsp;50 (principally 38th Street, Hopkins Street, Moss Avenue, Excelsior Avenue, and part of Foothill Boulevard) had been renamed for 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]].<ref>{{cite news |title = Naming Our City Streets |url = https://www.newspapers.com/clip/44517098/street-history/ |first = Albert E. |last = Norman |work = [[Oakland Tribune]] |date = October 23, 1960 |page = M17 |issn = 1068-5936 |access-date = February 15, 2020 |via = [[Newspapers.com]] |archive-date = September 8, 2022 |archive-url = https://web.archive.org/web/20220908162543/https://www.newspapers.com/clip/44517098/street-history/ |url-status = live }}</ref><ref>{{cite news |first = Gary |last = Peterson |url = https://www.mercurynews.com/2013/06/13/bay-area-roadways-whered-the-names-come-from/ |title = Bay Area Roadways: Where'd the Names Come From? |work = San Jose Mercury News |date = June 13, 2013 |access-date = August 28, 2018 |archive-date = August 29, 2018 |archive-url = https://web.archive.org/web/20180829000158/https://www.mercurynews.com/2013/06/13/bay-area-roadways-whered-the-names-come-from/ |url-status = live }}</ref>

The freeway was opened to traffic in eight segments until its completion in May 1966 (last segment, connecting with [[California State Route 238|SR&nbsp;238]] (now [[Interstate 238|I-238]]), in Castro Valley, opened May 20, 1966).<ref>{{cite magazine |first = D.C. |last = Ryman |date = March–April 1966 |title = MacArthur Freeway: Relief for the Nimitz Freeway |url = https://archive.org/details/califvol4546orniahighwa6667calirich/page/n69/mode/2up |magazine = California Highways and Public Works |volume = 45 |issue = 3–4 |pages = 12–15 |issn = 0008-1159 |access-date = September 7, 2022 |via = Internet Archive }}</ref>

===Oakland to San Rafael===
The segment of I-580 running from the [[MacArthur Maze]] to [[San Rafael, California|San Rafael]] is the most recent to be signed as I-580, beginning in 1984. Before 1984, this segment was part of [[California State Route 17|SR&nbsp;17]].

From the Maze to the interchange locally known as the "Hoffman Split" in [[Albany, California|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 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, California|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, California|San Rafael]], ending at an interchange with [[U.S. Route 101 in California|US&nbsp;101]]. This freeway segment supplanted an earlier boulevard constructed as part of SR&nbsp;17.

'''Interstate&nbsp;180''' ('''I-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 [[California State Route 17|SR&nbsp;17]] but was marked for inclusion in the Interstate Highway System.

Briefly the bridge used the number 180, despite the [[Fresno, California|Fresno]]-area [[California State Route 180|SR&nbsp;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&nbsp;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.
