**State Route 58** (**SR 58**) is a major east-west [state highway](/source/State_highway) in the [U.S. state](/source/U.S._state) of [California](/source/California) that runs across the [Coast Ranges](/source/California_Coast_Ranges), the southern [San Joaquin Valley](/source/San_Joaquin_Valley), the [Tehachapi Mountains](/source/Tehachapi_Mountains), which border the southern [Sierra Nevada](/source/Sierra_Nevada), and the [Mojave Desert](/source/Mojave_Desert). It runs between [U.S. Route 101](/source/U.S._Route_101_in_California) near [Santa Margarita](/source/Santa_Margarita,_California) and [Interstate 15](/source/Interstate_15_in_California) in [Barstow](/source/Barstow,_California). It has junctions with [Interstate 5](/source/Interstate_5_in_California) near [Buttonwillow](/source/Buttonwillow,_California), [State Route 99](/source/California_State_Route_99) in [Bakersfield](/source/Bakersfield,_California), [State Route 202](/source/California_State_Route_202) in [Tehachapi](/source/Tehachapi,_California), [State Route 14](/source/California_State_Route_14) near [Mojave](/source/Mojave,_California), and [U.S. Route 395](/source/U.S._Route_395_in_California) at Kramer Junction. SR 58 also provides access to [Edwards Air Force Base](/source/Edwards_Air_Force_Base). At various points it is known as the **Calf Canyon Highway**, **Carrisa Highway**, **Bakersfield-McKittrick Highway**, **Rosa Parks Highway**, **Westside Parkway**, **Barstow-Bakersfield Highway**, **Bakersfield Tehachapi Highway**, **Kern County Korean War Veterans Memorial Highway**, and **Mojave-Barstow Highway**.

## Route description

Route 58 is defined as follows in section 358, subdivision (a), of the [California Streets and Highways Code](/source/California_Codes):[1]

Route 58 is from:

(1) [Route 101](/source/U.S._Route_101_in_California) near [Santa Margarita](/source/Santa_Margarita,_California) to [Route 33](/source/California_State_Route_33). (2) Route 33 to [Route 43](/source/California_State_Route_43). (3) Route 43 to just west of Van Buren Place near [Bakersfield](/source/Bakersfield,_California). (4) Mohawk Street near Bakersfield to [Route 99](/source/California_State_Route_99). (5) Route 99 to [Route 15](/source/Interstate_15_in_California) near [Barstow](/source/Barstow,_California) via Bakersfield and [Mojave](/source/Mojave,_California).

Due to ongoing freeway construction projects in Bakersfield and unincorporated [Kern](/source/Kern_County,_California) and [San Bernardino](/source/San_Bernardino_County,_California) counties, the definition has yet to be amended by the legislature and may not accurately reflect current or former rights of way maintained by Caltrans. The definition also omits Route 58's [concurrencies](/source/Concurrency_(road)) with other routes instead of duplicating those segments in those other routes' definitions in the code.

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](/source/U.S._Route_101_in_California) near [Santa Margarita](/source/Santa_Margarita,_California), a few miles north of [San Luis Obispo](/source/San_Luis_Obispo,_California), 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](/source/California_State_Route_229). Alternatives such as [SR 46](/source/California_State_Route_46) to the north or [SR 166](/source/California_State_Route_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](/source/Carrizo_Plain), which is known for its scenic beauty and geological features, including the [San Andreas Fault](/source/San_Andreas_Fault). SR 58 then takes another winding road before joining with [State Route 33](/source/California_State_Route_33) in the small town of [McKittrick](/source/McKittrick,_California). 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](/source/Buttonwillow,_California). SR 58 then joins with the north-south [Interstate 5](/source/Interstate_5_in_California) (I-5) for a few miles to Stockdale Highway, where it resumes heading east and intersects with [State Route 43](/source/California_State_Route_43) before reaching Bakersfield. In Bakersfield, the route follows the Westside Parkway to reach [State Route 99](/source/California_State_Route_99) at the [West Bakersfield Interchange](/source/West_Bakersfield_Interchange).

East of SR 99, SR 58 briefly enters expressway status with two at-grade intersections in the [Caliente](/source/Caliente,_California) area before resuming freeway status east of Caliente. SR 58 then reaches the [Tehachapi](/source/Tehachapi,_California) city limits and traverses the [Tehachapi Pass](/source/Tehachapi_Pass) before dropping out of the [Tehachapi Mountains](/source/Tehachapi_Mountains) into the [Antelope Valley](/source/Antelope_Valley) at the town of [Mojave](/source/Mojave,_California). Freeway conditions continue from [State Route 14](/source/California_State_Route_14) east of Mojave bypassing [North Edwards](/source/North_Edwards,_California), [Edwards Air Force Base](/source/Edwards_Air_Force_Base), [Boron](/source/Boron,_California), and Kramer Junction. Approximately 10 miles (16 km) east of an interchange with [U.S. Route 395](/source/U.S._Route_395_in_California), SR 58 resumes expressway status with two lanes in each direction until just before reaching the easternmost terminus at [Interstate 15](/source/Interstate_15_in_California) in [Barstow](/source/Barstow,_California).

With the lack of four-lane or greater, divided highways that cross the [Sierra Nevada](/source/Sierra_Nevada) between SR 58 at the [Tehachapi Pass](/source/Tehachapi_Pass) and [Interstate 80](/source/Interstate_80_in_California) at [Donner Summit](/source/Donner_Summit) about hundreds of miles to the north, I-5 and SR 58 are used by motorists to travel between [Northern California](/source/Northern_California) and points to the southeast, such as [Las Vegas](/source/Las_Vegas,_Nevada) (via I-15) and [Interstate 40](/source/Interstate_40), without having to face the extreme traffic congestion of greater [Los Angeles](/source/Los_Angeles).

SR 58 is part of the [California Freeway and Expressway System](/source/California_Freeway_and_Expressway_System),[2] and east of I-5 is part of the [National Highway System](/source/National_Highway_System_(United_States)),[3] a network of highways that are considered essential to the country's economy, defense, and mobility by the [Federal Highway Administration](/source/Federal_Highway_Administration).[4] SR 58 is eligible for the [State Scenic Highway System](/source/State_Scenic_Highway_System_(California)),[5] but it is not officially designated as a scenic highway by the [California Department of Transportation](/source/California_Department_of_Transportation).[6] SR 58 has several names throughout its length, including the [Blue Star Memorial Highway](/source/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](/source/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]

## History

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](/source/Interstate_40_in_California); previous to 1964 it was a segment of [US 66](/source/US_66).

Prior to 1964, the segment of State Route 58 between Bakersfield and Barstow was signed [U.S. Route 466](/source/U.S._Route_466_(California)). Also at that time, the segment of SR 58 between [State Route 33](/source/California_State_Route_33) at [McKittrick](/source/McKittrick,_California) and State Route 99 in Bakersfield was signed as [State Route 178](/source/California_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](/source/Santa_Margarita,_California) and State Route 33 at McKittrick was not signed prior to 1964.

Note that US 466 was co-signed with [US 99](/source/US_99), now State Route 99, between Bakersfield and [Famoso Junction](/source/Famoso,_California). 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 in c. 2000.[citation needed] The former eastern terminus is now known as "Old Highway 58".

Freeway bypasses in Tehachapi, Boron, Mojave, Hinkley, and Kramer Junction were completed in c. 1975, 1981, 2003, 2017, and 2019, respectively.[citation needed]

### Westside Parkway and the Centennial Corridor Project

In western Bakersfield, the **Westside Parkway**, a freeway running from Stockdale Highway (near Heath Road) 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 built an extension of the Westside Parkway east to the junction of SR 58 and SR 99 at the [West Bakersfield Interchange](/source/West_Bakersfield_Interchange). Although construction was 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]

On February 5, 2021, the city transferred the Westside Parkway to Caltrans and [California Highway Patrol](/source/California_Highway_Patrol) jurisdiction.[12] City officials then announced in October 2022 that the project was nearly complete, and that they were working on the last 800 feet of the connection, specifically, the northbound SR 99 to westbound SR 58 transition ramp, with an estimated 8 months of construction left at the time.[13] Meanwhile, Caltrans began installing signage rerouting SR 58 traffic from [I-5](/source/Interstate_5_in_California) onto Stockdale Highway and the Westside Parkway east to at least Mohawk Street. Prior to, SR 58 immediately headed due east from I-5 to briefly join SR 43, then ran to Bakersfield along Rosedale Highway.[14][15][16]

The Centennial Corridor was inaugurated on February 9, 2024, with a ceremonial bicycle ride,[17] and officially opened to traffic on February 17, 2024.[18][19] The rest of SR 58 on Rosedale Highway between Mohawk Street and SR 99 is planned to be transferred to city control.[20][21] Future plans are to upgrade Stockdale Highway from I-5 to Heath Road as a freeway.[22]

## Business loops

### Tehachapi

**State Route 58 Business** (**SR 58 Bus.**) is a [business route](/source/Business_route) of California State Route 58 in [Tehachapi](/source/Tehachapi,_California). It provides access to downtown Tehachapi as **Tehachapi Boulevard**. It also follows the former routing of [U.S. Route 466](/source/U.S._Route_466_in_California) and is overlapped with [State Route 202](/source/California_State_Route_202).

**Major intersections**

### Mojave

**State Route 58 Business** (**SR 58 Bus.**) is a [business route](/source/Business_route) of California State Route 58 that runs through [Mojave](/source/Mojave,_California). It provides access to downtown Mojave as **Mojave-Barstow Highway**. It follows mostly the former routing of [U.S. Route 466](/source/U.S._Route_466_(California)).

**Major intersections**

### Boron

**State Route 58 Business** (**SR 58 Bus.**) is a [business route](/source/Business_route) of California State Route 58 that runs between [Boron](/source/Boron,_California) and Kramer Junction. It provides access to downtown Boron as **Twenty Mule Team Road**. It also follows the former routing of [U.S. Route 466](/source/U.S._Route_466_(California)). It is signed from SR 58 at Borax Road to the old SR 58 split near the [Kern](/source/Kern_County,_California)–[San Bernardino](/source/San_Bernardino_County,_California) county line (where the old SR 58 now [dead ends](/source/Dead_end_street) following the 2020 completion of the freeway bypass in Kramer Junction). From here to US 395 in Kramer Junction, following the old alignment of SR 58 (and US 466), the business route is unsigned.
