Sierra Highway
Sierra Highway or El Camino Sierra is a historic route in California, United States, that connects Los Angeles with the Eastern Sierra and Lake Tahoe. The trail formed in the 19th century before it was rebuilt as highways in the early 20th century. It follows parts of modern State Route 14, U.S. Route 395 and State Route 89. Two portions of this road are currently explicitly signed as Sierra Highway. The first is an old alignment of SR 14 (former U.S. Route 6) from Los Angeles to Mojave. This road is also signed with the unusual designation of State Route 14U through the city of Santa Clarita, and unsigned with the same 14U designation in the city of Los Angeles. The second part signed as Sierra Highway is a portion of US 395 in Bishop.
Traversing the extremes of California, from the Mojave Desert to the Sierra Nevada, El Camino Sierra has been advertised to the world as a highway to showcase the natural beauty of California as far back as 1910. Though most of the original Sierra Highway was rebuilt or bypassed in the early 1970s with modern highways, the road is still well known. The portion through the San Gabriel Mountains is noted as the primary filming location for the film Duel.
El Camino Sierra connects Los Angeles with Lake Tahoe along the eastern edge of California, serving the counties of Los Angeles, Kern, Inyo, Mono, Alpine and El Dorado. The highway exists as a roadway now called Sierra Highway from Los Angeles to Mojave. North of Mojave, El Camino Sierra is better known by the numbered designations in current use. While traversing the state, the highway crosses several mountain passes. The highway crests the San Gabriel Mountains via Soledad Pass. While in the Sierra Nevada the highway crosses Sherwin Summit, Deadman Summit, Conway Summit, Devil's Gate Pass, Monitor Pass and Luther Pass.
Sierra Highway begins at Tunnel Station within the northernmost limits of the City of Los Angeles, where it intersects with San Fernando Road. This junction was historically the intersection of U.S. Route 99 and U.S. Route 6. It is located adjacent to the intersection of the replacement freeways, the Newhall Pass interchange of Interstate 5 and State Route 14. The highway then enters an unincorporated area of Los Angeles County before becoming one of the main thoroughfares of the City of Santa Clarita.
From Los Angeles and through Santa Clarita, Route 14 was moved to the Antelope Valley Freeway alignment in 1971; however, the process to decommission the old alignment of Route 14 is not complete. As a result, the segment within Los Angeles and a portion within Santa Clarita carry the designation of State Route 14U, the U signifying "un-relinquished". Formal specifications for Route 14U are not published on Caltrans logs, but the route's existence is acknowledged in both Caltrans' bridge inventory logs and its postmile query tool. According to the City of Santa Clarita, Caltrans maintains Sierra Highway (14U) within the city from about 500 feet (0.15 km) north of Newhall Avenue to Whispering Leaves Drive. The remaining part of Sierra Highway through the City of Santa Clarita is maintained by the city and not part of the 14U designation. In 2018 Caltrans funded a new pedestrian overpass as one item on a list of requested improvements by the city before they accept relinquishment of the road from the state.
Sierra Highway, modern Route 14, and a main line of the Union Pacific Railroad all cross the San Gabriel Mountains, cresting the mountains at Soledad Pass (elevation 3,179 feet (969 m)). The three transportation arteries use different paths up the mountains, separating at Santa Clarita and converging near Acton. Sierra Highway uses Mint Canyon, the railroad uses Soledad Canyon and the modern Route 14 is a hybrid route using the ridges and side canyons between the two older routes. These canyons are formed by the Santa Clara River and its tributaries.
Upon exiting the mountains, Sierra Highway enters the Antelope Valley and serves as one of the main streets of Palmdale, Lancaster, and Rosamond. The highway runs parallel to the modern Route 14 and the railroad, becoming a frontage road. Just shy of Mojave the freeway portion of Route 14 ends, while the frontage road becomes a dirt path and eventually terminates. From this point, the canonical route of Sierra Highway joins State Route 14, passing through downtown Mojave.
North of Mojave the alignments of State Routes 14 and 89, and U.S. Route 395 have not significantly changed since first paved, and are called El Camino Sierra. Significant portions have been upgraded to a divided highway; however, most of the upgrades used the same alignment as the old two lane road. The highway cuts across Red Rock Canyon State Park to follow a series of valleys along the crest of the Sierra Nevada. While traversing the Owens Valley, the Sierra Highway passes Mount Whitney, the highest point in the contiguous United States, 10,000 feet (3,000 m) above the highway. As of 2009, the only other signed section of Sierra Highway is a portion of U.S. 395 past the separation with U.S. 6 in Bishop.
