Imperial Highway was initially conceived as a commercial route connecting Imperial County to Los Angeles County. [1] 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.
