In 1963 and 1964, the California Division of Highways, at the behest of the California State Legislature, 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 by the Legislature on September 20, 1963. Signage changes took place by July 1, 1964.[1]
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. South of Sacramento, US 99 became an extended State Route 111, a new State Route 86, Interstate 10, Interstate 5, State Route 99, and a new State Route 204. US 99E became Interstate 80, an extended State Route 65, a new State Route 70, and State Route 99, while US 99W became Interstate 80, a new State Route 113, and Interstate 5. US 99 north of the merge also became Interstate 5.
- U.S. Route 101 was truncated to Los Angeles; the eliminated portion became part of Interstate 5 and a new State Route 72. Two parts became freeway; the old route became State Route 82 and State Route 254.
- U.S. Route 101 Bypass in the San Francisco Bay Area became a relocated U.S. Route 101.
- U.S. Route 101 Alternate in Southern California became part of an extended State Route 1.
- U.S. Route 101 from San Jose to San Francisco became a new State Route 82.
- U.S. Route 299 became the majority of the new State Route 299.
- U.S. Route 399 became an extension (and relocation) of State Route 33 and a new State Route 119.
- U.S. Route 466 became a relocation of State Route 41, a new State Route 46, a new State Route 58, and Interstate 15.
- U.S. Route 95, U.S. Route 97, U.S. Route 199 and U.S. Route 395 remained the same. (US 395 has since been truncated at Adelanto. and now part of Interstate 15 from Adelanto to its north junction with Interstate 215, Interstate 215 to its south junction with Interstate 15, Interstate 15 to State Route 163, and State Route 163 to Interstate 5 in San Diego.)
