State Route 58 (SR 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, Bakersfield Tehachapi Highway, Kern County Korean War Veterans Memorial Highway, and Mojave-Barstow Highway.

Route description

State Route 58 between Santa Margarita and Buttonwillow is a winding mountain road through a thinly populated area. From its westernmost terminus at US 101 near Santa Margarita, a few miles north of San Luis Obispo, SR 58 heads east along the former US 101 (El Camino Real) for one mile. SR 58 then heads east and up the winding mountain road, passing through a thinly populated area and an intersection with SR 229. Alternatives such as SR 46 to the north or SR 166 to the south are recommended, as much of this section of SR 58 is prohibited to truck traffic. However, this section of SR 58 does pass through the Carrizo Plain, which is known for its scenic beauty and geological features, including the San Andreas Fault. SR 58 then takes another winding road before joining with State Route 33 (SR 33) in the small town of McKittrick. SR 33 then splits at the north end of McKittrick before SR 58 then enters another, but brief winding road. SR 58 then proceeds northeast for several miles before changing to an east-west alignment and reaching Buttonwillow. A few miles later, SR 58 has an interchange with Interstate 5 (I-5). Approximately 7 miles (11 km) east of I-5, SR 58 briefly joins SR 43 before continuing east and eventually reaching the Bakersfield city limits.

State Route 58 joins State Route 99 for about 2 miles (3.2 km) through Bakersfield before splitting as a freeway and heading east. SR 58 briefly enters expressway status with two at-grade intersections in the Caliente area before resuming freeway status east of Caliente. SR 58 then reaches the Tehachapi city limits and traverses the Tehachapi Pass before dropping out of the Tehachapi Mountains into the Antelope Valley at the town of Mojave. Freeway conditions continue from State Route 14 east of Mojave bypassing North Edwards, Edwards Air Force Base, Boron, and Kramer Junction. Approximately 10 miles (16 km) east of an interchange with U.S. Route 395, SR 58 resumes expressway status with two lanes in each direction until just before reaching the easternmost terminus at Interstate 15 in Barstow.

State Route 58 is a freeway from its south junction with SR 99 in Bakersfield (the West Bakersfield Interchange) to several miles east of Mojave (a freeway bypass of Mojave was completed in 2004), except for two at-grade intersections two miles (3.2 km) apart in the Caliente area. Other freeway segments are bypasses of Boron, Kramer Junction (a freeway bypass of Kramer and Kramer Junction was completed in 2019), and Barstow. Except for the Boron-Kramer Junction freeway bypass, SR 58 is primarily a four-lane expressway (two lanes per direction) from just east of Kramer Junction up to the Barstow bypass segment.

State Route 58 takes the southernmost route through the Sierra Nevada and allows motorists to travel between Northern California and points to the east, such as Las Vegas and Interstate 40, without having to face the extreme traffic congestion of greater Los Angeles. State Route 58 and Interstate 80 are the only freeways to cross the Sierra Nevada. The route also offers an alternative to the often treacherous Donner Pass to truckers traveling from the San Francisco Bay Area to points eastward; prior to the construction of Interstate 80, the road (as U.S. Route 466) was heavily used for this purpose.

SR 58 is part of the California Freeway and Expressway System,[2] and east of I-5 is part of the National Highway System,[3] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[4] SR 58 is eligible for the State Scenic Highway System,[5] but it is not officially designated as a scenic highway by the California Department of Transportation.[6] SR 58 has several names throughout its length, including the Blue Star Memorial Highway (for its entire length); the Kern County Korean War Veterans Memorial Highway, for the section from SR 184 to the Kern County/San Bernardino County Line; and the Rosa Parks Highway, for the section between SR 99 and SR 184. The Korean War Veterans name honors the approximately 8,120 veterans from Kern County, while the section named for Rosa Parks honors the civil rights activist.[7] The portion of SR 58 from Barstow to Bakersfield is sometimes referred to as the Barstow–Bakersfield Highway.[8]

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".

Westside Parkway and the Centennial Corridor Project

In western Bakersfield, the Westside Parkway, a freeway running from the intersection of Heath Road and Stockdale Highway east to Truxtun Avenue, was completed on April 15, 2015, with interchanges in between at Allen Road, Calloway Drive, Coffee Road, and Mohawk Street.[9] Opening in stages since 2013, the road was originally under the jurisdiction of the city of Bakersfield. As part of the Centennial Corridor project, Caltrans is building an eastern extension of the Westside Parkway to the current junction of highways 58 and 99 at the West Bakersfield Interchange, but construction has been controversial since it displaced dozens of homes and businesses;[10] by September 2017, all but a few buildings in the path had been demolished.[11] Once the connection to Highway 99 is completed (which is expected to occur in Fall 2022[12]), Highway 58 will then be rerouted onto Stockdale Highway and the Westside Parkway, with later plans to upgrade Stockdale Highway from Heath Road west to Interstate 5 as a freeway.[13] Bakersfield has already begun the transfer process, and the Westside Parkway is under Caltrans and California Highway Patrol jurisdiction effective February 5, 2021.[14]

Major intersections

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see the list of postmile definitions).[15] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.

Westside Parkway (Future SR 58)

This exit list consists of the Bakersfield city-maintained freeway that will eventually become part of SR 58. All exits are unnumbered. Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see the list of postmile definitions).[15] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Kern County.
