Imperial Highway

The Imperial Highway is a west-east thoroughfare in the counties of Los Angeles, Orange, San Diego, and Imperial in California. The main portion of the existing route begins at Vista Del Mar in Los Angeles near the Los Angeles International Airport and ends at the Anaheim - Orange line at Via Escola where it becomes Cannon Street. Formerly, the Route used to extend from Vista Del Mar to Calexico, where a portion of the highway still exists, but the Route was replaced with other highways, rendering the older portions of the Imperial Highway to fall out of use.[1]

Imperial Highway was initially conceived as a commercial route connecting Imperial County to Los Angeles County. [2] A segment remains today in Imperial County which connects Interstate 8 near Ocotillo, California. Another segment adjacent to Lake Elsinore (Riverside County) was once indicated on 1960s vicinity maps by H.M. Gousha (Gousha), publisher of street maps.
