Since the current state highway system in California, United States was designated, several routes have been deleted from the system by the California Department of Transportation (Caltrans) and the California State Legislature.

State Route 21 closely followed the route of current Interstate 680. It began in San Jose heading northeast from I-280 and US 101 and closely paralleling SR 17 (now I-880) until reaching Fremont. From there, SR 21 headed northeast toward Pleasanton and intersected I-580. SR 21 then headed northwest to Concord and Martinez, California, intersecting SR 24 and SR 4 before reaching the Carquinez Strait. In Benicia, SR 21 intersected with SR 141 (now I-780) and ended in Fairfield at I-80.
