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. Many formerly unsigned routes received sign numbers corresponding to their new legislative numbers. A smaller change was the removal and truncating of many U.S. Routes in favor of the Interstate Highways (designated in 1959), and the renumbering of State Routes that conflicted with Interstate numbers. 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. Changes in sign routes U.S. Routes U.S. Route 6 was truncated to Bishop. The part south of Bishop was replaced by U.S. Route 395, State Route 14, Interstate 5, State Route 11 (now renumbered Interstate 110), and State Route 1 to the old U.S. 6 terminus at the Los Alamitos Circle in Long Beach. U.S. Route 40 became Interstate 80. U.S. Route 40 Alternate became new State Route 113 and State Route 70. U.S. Route 40 Business became new State Route 123. U.S. Route 50 was truncated to Sacramento. West from Sacramento, it became new State Route 99, existing State Route 4, Interstate 5, Interstate 205, Interstate 580, and Interstate 80. U.S. Route 60 became Interstate 10 east of Beaumont and the new State Route 60 west from Beaumont to the East L.A. interchange. U.S. Route 66 was truncated to Pasadena, becoming State Route 159 (from U.S. Route 66 Alternate) and an extension of State Route 2. East of Pasadena, it was continued to be signed, but was officially State Route 248, Interstate 210, State Route 30 (extended from its pre-1964 route), State Route 66, Interstate 15 and Interstate 40. U.S. Route 66 Alternate became State Route 159. U.S. Route 70 became Interstate 10 and State Route 212 and was eliminated in California (it now terminates in Globe, Arizona). U.S. Route 80 became Interstate 8 and was deleted from California (its terminus is now in Dallas, Texas). U.S. Route 91 became existing State Route 19, new State Route 214, part of new State Route 91, and Interstate 15. U.S. Route 99 was eliminated, along with U.S. Route 99E and U.S. Route 99W.
