to the Nevada state line. It was signed as a U.S. Highway.
In the 1970 California Streets and Highways Code there was an additional provision
to Route 40, stating that Route 40 was from Route 15 to the Arizona state line near
Topock, Arizona via Needles, together with an extension from a point on such Route 40 near
Needles easterly by the most direct and practicable route to the Arizona-California line
at the Colorado River, including a bridge over and across said river, to be constructed,
owned, operated, and maintained jointly with the State of Arizona.
Route 58 from Route 5 to Route 40 via Bakersfield and the Tehachapi Pass was twice
