List of deleted state highways in California
Since the current state highway system in California was designated, several routes have been deleted from the system by the California Department of Transportation and the California State Legislature.
Some of them were deleted before or during the 1964 state highway renumbering.State Route 7 ran from SR 1 near SR 47 in Long Beach to Valley Boulevard in Monterey Park as the Long Beach Freeway. Originally running as State Route 15 in 1934, the route was changed to prevent confusion with Interstate 15. In 1985, SR 7 was deleted and has since been renumbered as I-710. SR 7 was redesignated in Calexico from I-8 near Holtville to the United States/Mexico border in 1990. This route was completed in 2005.State Route 11 followed the route of current Route 110 along the Harbor Freeway and the Arroyo Seco Parkway. It initially followed surface streets until the 1940s when the Arroyo Seco Parkway was completed. The Harbor Freeway, which was constructed to interstate standards, opened in phases from the late 1950s to the 1970s and SR 11 was since transferred to that route. In December 1978, the Harbor Freeway was approved as an Interstate Highway by the FHWA. In 1981, SR 11 was deleted and has since been renumbered as Interstate 110 on the Harbor Freeway, and State Route 110 on the Pasadena Freeway.
SR 11 was redesignated in San Diego from SR 905 near SR 125 to the United States/Mexico border in 1994 and the first segment opened in 2016.State Route 21
State Route 21 closely followed the route of current Interstate 680. It began in San Jose heading northeast from I-280 and US 101 and closely paralleling SR 17 until reaching Fremont. From there, SR 21 headed northeast toward Pleasanton and intersected I-580. SR 21 then headed northwest to Concord and Martinez, California, intersecting SR 24 and SR 4 before reaching the Carquinez Strait. In Benicia, SR 21 intersected with SR 141 and ended in Fairfield at I-80.
The route was added to the Interstate Highway System in 1973. This became the new alignment of I-680, and the old route to Vallejo became I-780. SR 21 was then deleted in 1976 once corresponding changes were made by the state legislature.State Route 30 ran from Interstate 210 in San Dimas to Interstate 10 in Redlands through San Bernardino. It was built to freeway standards between Interstate 215 in San Bernardino and Interstate 10 and between the current terminus of State Route 57 in San Dimas to Foothill Boulevard in La Verne. When the freeway section between Foothill Boulevard and Interstate 215 was completed in 2007, the route was decommissioned and renumbered SR 210. It is expected to be incorporated into the Interstate highway system at some later date as an extension of Interstate 210.State Route 31
State Route 31 ran from State Route 91 near Corona to Interstate 15 in Devore through San Bernardino. The route was deleted in 1974, when it was added to the interstate system. After being signed California 31, It was signed Temporary Interstate 15, and later, after being moved from Main Street in Corona, Hamner Avenue in Riverside County north of Corona, and Milliken Avenue in San Bernardino County to the Ontario Freeway. The route became Interstate 15.State Route 42 ran from State Route 1 west of Inglewood to State Route 91 near Norwalk, largely along Manchester Avenue and Firestone Boulevard. It was deleted in 2000. The segment east of Interstate 5 was added to State Route 90. The segment west of Interstate 5 was added to the interstate system as Interstate 105. The freeway would not be opened until 1993, which resulted in the original route continuing to be signed as State Route 42. To this day, Route 42 is still sporadically signed in many places.State Route 69
State Route 69 began at SR 198 amid Tulare County. It then headed north and intersected SR 216 in Woodlake and CR J27 amid farmland in the county. The route continued to meet SR 201 in Elderwood. After several miles through Tulare County, it crossed into Fresno County, where it met its north end at State Route 180. In 1972, this highway was decommissioned and renumbered SR 245.State Route 106 was originally created in 1964, and ran from State Route 38 in Redlands to State Route 18 in Running Springs. Prior to 1964, the highway was a part of Legislative Route 190, which ran from U.S. Route 66 to State Route 38. After 1964, the route was split in half. The western portion became State Route 30. The eastern portion was combined with Legislative Route 207, and became State Route 106. A year later, its southern terminus was moved to Interstate 10. In 1972, State Route 106 was decommissioned. The northern portion between State Route 30 and State Route 18 was renumbered to State Route 330. The southern portion was added to State Route 30, extending it to Interstate 10. This also reconnected both halves of the original Legislative Route 190.State Route 157
State Route 157 was planned to run from I-805 near Ocean View Boulevard in San Diego to SR 125 near Sweetwater Reservoir, passing through the neighborhood of Paradise Hills. What was known as Route 285 became a state highway in 1959, and was redesignated as SR 157 in the 1964 state highway renumbering. By 1974, plans called for constructing the freeway from Nogal Street across Imperial Avenue to end at SR 54. However, the project was cancelled after objections from the community, and because it was not compatible with any long-term plans. Developments near the western half of the route served to discourage construction, and the plans for the eastern half were cancelled that year; the land was sold soon afterward. The mayor of National City, Kile Morgan, opposed the proposal, citing concerns that many projects for the South Bay were being opposed by others. The route was removed from the law by the Legislature in 1994.State Route 159
Between July 1, 1964, and the time it was turned back to local authorities, State Route 159 was the segment of Linda Vista Avenue in Pasadena between State Route 134, the Ventura Freeway, and Interstate 210, the Foothill Freeway. From July 1, 1964, to 1965, this was also the segment of Figueroa Street between State Route 134 and Interstate 5. In 1965, this was to be deleted when I-210 was completed. Prior to July 1, 1964, it was a segment of California Legislative Route 165 and signed as California State Route 11.State Route 171
State Route 171 was planned to run from I-5 near San Diego to I-805 through Switzer Canyon. It was to be called the Switzer Canyon Freeway, and had been suggested by consultant John Nolen in 1926. Originally designated as Route 284 in 1959, the route was renumbered as SR 171 in the 1964 state highway renumbering. However, the community opposed the project; it would have passed through Balboa Park and would have gone through canyons, residential districts, and a golf course. SANDAG endorsed the deletion in 1993, and the Legislature deleted the route in 1994.State Route 176 ran from US 101 in Santa Maria to Sisquoc along Stowell Road, Philbric Road, and Foxen Canyon Road. Prior to July 1, 1964, it was an unsigned segment of California Legislative Route 148.State Route 195
State Route 195 connected SR 86 with SR 111. It served as a connector between the two routes while the SR 86 expressway was constructed. This route was deleted in 2014, when the part that was not deleted in 2009 was transferred to SR 111.State Route 196
State Route 196 was planned to run from Route 2 to Route 249 south of Palmdale. It was deleted before it could be constructed in 1965.State Route 206
State Route 206 was deleted from the state highway system, with varying reasons. Between July 1, 1964, and the time it was turned back to local authorities, Route 206 ran from Highland Avenue, formerly State Route 30, in San Bernardino along North E Street, Kendall Drive, and Palm Avenue to the Barstow Freeway, Interstate 215, in Verdemont. Prior to July 1, 1964, Route 206 was California Legislative Route 191 and was signed as Business U.S. 66.State Route 208 was a state highway in Mendocino County that from Rockport to US 101 in Leggett. The route was entirely concurrent with SR 1. This route was deleted in 1984.State Route 209
State Route 209 connected Point Loma with the interchange of I-5 and I-8 in San Diego. The route began at Cabrillo National Monument and passed through Fort Rosecrans and the neighborhood of Point Loma via Catalina Boulevard, Canon Street, and Rosecrans Street. This route was deleted in 2003.State Route 214 was deleted in 1998. Between July 1, 1964, and the time it was turned back to local authorities, Route 214 ran between Lakewood Boulevard, then State Route 19, in Long Beach and the Santa Ana Freeway, Interstate 5, in Anaheim. Route 214 traversed Carson Street in Los Angeles County. It continued into Orange County on Lincoln Avenue. Prior to July 1, 1964, Route 214 was a segment of California Legislative Route 178. Between 1962 and July 1, 1964, it was signed as US 91. Before 1962, it was signed as both US 91 and State Route 18.State Route 224
State Route 224 was a spur route connecting U.S. Route 101 in Carpinteria to Carpinteria State Beach. From US 101, it ran south along Casitas Pass Road, then west on Carpinteria Avenue before heading south again along Palm Avenue to the beach's entrance. The route was defined in the 1964 state highway renumbering, then deleted in 1996.State Route 228
State Route 228 was to be a short bypass west of Brawley. The road as defined by the California State Legislature in the 1964 state highway renumbering would have begun at SR 86 southwest of Brawley and ended west of Brawley. However, this was also included in the 1935 definition of Route 26, which continued north to Los Angeles and south to Calexico, along the approximate route of US 99. The route was deleted in 1998; by that time, no highway had been constructed along this route.
