Interstate 580 (I-580) is an approximately 82-mile-long (132 km) east–west auxiliary Interstate Highway in Northern California. The heavily traveled spur route of I-80 runs from US 101 in San Rafael in the San Francisco Bay Area to I-5 near 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 the Bay Area to the east.
