Interstate 980
Interstate 980 (I-980) is a short 2.03-mile (3.27 km) auxiliary Interstate Highway entirely within Oakland in Northern California, connecting I-580 and State Route 24 (SR 24) to I-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 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.

I-980 was used as an alternate route between Oakland and San Francisco when the Cypress Viaduct carrying I-880 collapsed in the 1989 Loma Prieta earthquake. Traffic headed from the south would have to use I-980 to I-580 west to I-80 west to get across the San Francisco–Oakland Bay Bridge to reach San Francisco. This ended when I-880 reopened on a new alignment in 1997 (1998 to and from I-80 east).
