(July 2000) San Diego, CA. California still put the state name on its interstate signs. All signage in California appears now as it did in 1965.
California is the only state that still uses cut-out US highway shields - very distintive. This particular sign is from 1973 (Collection of Robert Edgar).
Porcelain US highway sign with "cats-eye" reflectors from the late 1940's or early 1950's. California had a unique way of signing its roads. In the early days of roads, the major automobile clubs of California would erect signage in the areas that they served. The signs were high quality porcelain signs with the club logo at the bottom of the sign. In 1947, the California Division of Highways (later CalTrans) took over erecting state and US highway markers, but continued the tradition of putting its logo on the bottom of the signs. This sign has the Division of Highways logo at the bottom (Collection of Robert Edgar).
Another porcelain US highway marker - this one without "cats-eye" reflectors, which would date it back to the late 20's or early 30's. This sign was erected by the Automobile Club of Southern California (Collection of Robert Edgar).
This sign is from 1931 and was also erected by the California State Autombile Association. (Collection of Robert Edgar).
