980

Interstate 980 (I-980) is a short 2.0-mile (3.2 km) auxiliary Interstate Highway spur entirely within the City of Oakland in Northern California, connecting Interstate 580 and State Route 24 to Interstate 880 near Downtown Oakland. I-980 passes the Oakland Convention Center and near the famous Jack London Square. I-980 is commonly considered the dividing line between Downtown Oakland and West Oakland. The freeway was planned as the eastern approach to the San Francisco Bay Southern Crossing. It is officially known as the John B. Williams Freeway, after the former director of the City of Oakland's Office of Community Development.
Interstate 980 was used as an alternate route between Oakland and San Francisco when the Cypress Viaduct carrying Interstate 880 collapsed in the Loma Prieta earthquake in 1989. Traffic headed from the south would have to use 980 to 580 west to Interstate 80 west to get across the Bay Bridge to reach San Francisco. This ended when Interstate 880 reopened on a new alignment in 1997 (1999 to and from I-80 east).
