Example of a county route shield in California

In the U.S. state of California, county routes are controlled and maintained by the county they reside in. They are generally patrolled however by the state's California Highway Patrol. They are designated with a letter (A, B, D, E, G, J, N, R, S depending on the part of the state, several counties split between two region prefixes) followed by a number (example: G2). These routes are all part of the California Route Marker Program which was established in 1958. This program was incorporated into the National Uniform County Route Marker Program created by the National Association of Counties in 1967. Not all counties choose to use the same marker; some have different systems of numbering their county routes.
