Interstate 580

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 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 Livermore resident and California Highway Patrol officer killed while chasing down a DUI driver). This route is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System.
