I-680 succeeded State Route 21 as the primary Benicia-Fremont highway in the mid-1960s. At that time, I-680 was constructed between the newly truncated Route 21's terminus in Benicia and Interstate 80 (née US 40) in Vallejo. In 1976, that segment became Interstate 780, and the 680 designation was moved to the last remaining portion of Route 21, which connected Benicia to Cordelia. This effectively established 680 as the outer East Bay's main connection to northern areas of the Central Valley, including Sacramento. California State Route 21, or California 21 or CA-21 for short, is the name of a defunct north-south highway, which Interstate 680 has wholly supplanted in the eastern part of the San Francisco Bay Area. ...
