Vintage Chevron East Bay Cities street map - 1958. Close-up of the regional map showing the routing of U.S. 40 stretching from Crockett to Davis. Cartography by H.M. Gousha.

Note the "Alternate U.S. 40" route (shared with U.S. 99W) which branched off at Davis. This alternate route ran to Reno via the Feather River Canyon.
