context_page_description: State Route 58 is a major east-west state highway in the U.S. state of California that runs across the Coast Ranges, the southern San Joaquin Valley, the Tehachapi Mountains, which border the southern Sierra Nevada, and the Mojave Desert. It runs between U.S. Route 101 near Santa Margarita and Interstate 15 in Barstow. It has junctions with Interstate 5 near Buttonwillow, State Route 99 in Bakersfield, State Route 202 in Tehachapi, State Route 14 near Mojave, and U.S. Route 395 at Kramer Junction. SR 58 also provides access to Edwards Air Force Base. At various points it is known as the Calf Canyon Highway, Carrisa Highway, Bakersfield-McKittrick Highway, Rosa Parks Highway, Rosedale Highway, Barstow-Bakersfield Highway, Kern County Korean War Veterans Memorial Highway, and Mojave-Barstow Highway.
context_section_description: State Route 58 did not exist as a California sign route until 1964, although previous to 1964, it was part of California Legislative Route 58. The other part of Legislative Route 58 is California's segment of Interstate 40; previous to 1964 it was a segment of US 66.
  Prior to 1964 the segment of State Route 58 between Bakersfield and Barstow was signed U.S. Route 466. Also at that time, the segment of SR 58 between State Route 33 at McKittrick and State Route 99 in Bakersfield was signed as State Route 178. Although it was proposed for signing as Route 178 in 1934, the segment of Legislative Route 58 between US 101 near Santa Margarita and State Route 33 at McKittrick was not signed prior to 1964.
  Note that US 466 was co-signed with US 99, now State Route 99, between Bakersfield and Famoso Junction. Between Famoso and US 101 at Paso Robles, US 466 largely became SR 46.
  The eastern terminus was originally at I-15 in northeastern Barstow. SR 58 was rerouted to I-15 in Barstow south of the I-40 interchange. The former eastern terminus is now known as "Old Highway 58."
