In 1963 and 1964, the California Division of Highways implemented a major renumbering of its state highways. The majority of ''sign routes''—those marked for the public—kept their numbers; the main changes were to the ''legislative routes'', which had their numbers changed to match the sign routes.

Some U.S. Routes that were officially removed continued to be signed until the replacement Interstates were completed. The state law authorizing the renumbering was passed on September 20, 1963. Signage changes took place by July 1, 1964.
