State Route 58 (SR 58) is an east-west highway across the California Coast Ranges, the southern San Joaquin Valley, the Tehachapi Mountains, which border the southern Sierra Nevada, and the Mojave Desert. It runs between its western terminus near Santa Margarita (junction U.S. Route 101) and its eastern terminus at Barstow (junction Interstate 15). It has junctions with Interstate 5 near Buttonwillow, State Route 99 in Bakersfield, State Route 202 in Tehachapi, State Route 14 in Mojave, and U.S. Route 395 at Kramer Junction. Route 58 gives good 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.

Route description

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, Route 58 heads east along the former US 101 (El Camino Real) for one mile, where Route 58 splits from El Camino Real. Route 58 then heads east and up the winding mountain road, passing through thinly populated area and an intersection with State Route 229. Alternatives such as State Route 46 to the north or State Route 166 to the south are recommended, as much of this section of Route 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. Route 58 then takes another winding road before joining with State Route 33 in the small town of McKittrick. Route 33 then splits at the north end of McKittrick before Route 58 then enters another, but brief winding road. Route 58 then proceeds northeast for several miles before changing to an east-west alignment and reaching Buttonwillow. A few miles later, Route 58 has an interchange with Interstate 5. Approximately 7 miles (11 km) east of Interstate 5, Route 58 briefly joins State Route 43 before continuing east and eventually reaching the Bakersfield city limits.

Route 58 joins State Route 99 for about 1 mile (1.6 km) through Bakersfield before splitting as a freeway and heading east. Route 58 briefly enters expressway status with two at-grade intersections in the Caliente area before resuming freeway status east of Caliente. Route 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. Shortly after an intersection with State Route 14, Route 58 reverts to an expressway east of Mojave before resuming freeway status bypassing North Edwards, Edwards Air Force Base, and Boron. East of Boron, Route 58 reverts to one lane in each direction before an at-grade signal intersection with U.S. Route 395. Approximately 10 miles (16 km) east of Route 395, Route 58 resumes expressway status with two lanes in each direction until just before reaching the easternmost terminus at Interstate 15 near Barstow.

Route 58 is a freeway from its south junction with Route 99 in Bakersfield (West Bakersfield Interchange) to several miles east of Mojave (a freeway bypass of Mojave was completed in 2004), except for two grade-level intersections two miles (3.2 km) apart in the Caliente area. There is another grade level intersection east of Mojave and west of the main Edwards AFB north gate exit where California City Blvd. intersects it. Other freeway segments are bypasses of Boron and Barstow. Except for the Boron freeway bypass, SR 58 is primarily a four-lane expressway (two lanes per direction) just east of Boron up to the Barstow bypass segment with the exception of the portion of Route 58 between Boron and approximately 5 miles (8.0 km) east of Kramer Junction, which is currently two-lane highway and is not yet an expressway.

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. 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 Route 184 to the Kern County/San Bernardino County Line; and the Rosa Parks Highway, for the section between Route 99 and Route 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 the 58 from Barstow to Bakersfield is sometimes referred to as the Barstow–Bakersfield Highway.[8]

History

Westbound 58 in the Temblor Range, descending into the Carrizo Plain
A truck passes eastbound along the busy Highway 58 through the Antelope Valley. The Tehachapi Mountains are visible in the distance.

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 SR 58 between Bakersfield and Barstow was signed U.S. Route 466. Also at that time, the segment of Route 58 between State Route 33 at McKittrick and 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 north of Barstow. Route 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."

Future

California has long sought federal funds for an extension of Interstate 40 west of Barstow; any such extension would use the general path of Route 58, if not existing highway, as far west at least as Bakersfield, whose rapid growth has made it a significant generator of traffic in its own right. The desired highway is being built piecemeal as Caltrans has funds available, at least between Mojave and Barstow. Two at-grade intersections within 1 1⁄2 miles (2.4 km) of each other around mile 76, roughly halfway between Bakersfield and Mojave (Bealeville Road and California State Route 223), would have to be either closed or upgraded to interchanges for the whole of Route 58 to be up to Interstate standards.

In the Kramer Junction area, Caltrans is planning to realign and widen a 13.3 mile segment of State Route 58 from 0.4 miles west of the Kern/San Bernardino County line to a point which is approximately 7.5 miles east of Kramer Junction from a two-lane conventional highway to a four-lane expressway; and construct an interchange at the 58/US 395 junction. This will replace the at-grade junction of Route 58 and US 395 in Kramer Junction.[9] A groundbreaking ceremony for the Kramer Junction Expressway was held on January 19, 2018.[10]

In western Bakersfield, the Westside Parkway, a freeway running from intersection of Heath Road and Stockdale Highway east to Truxtun Avenue, was completed in April 15, 2015, with interchanges at Allen Road, Calloway Drive, Coffee Road, Mohawk Street, and Truxtun Avenue.[11] Opening in stages since 2013, the road is currently under the jurisdiction of the city of Bakersfield. As part of the Centennial Corridor project, Caltrans plans to build an eastern extension of the Westside Parkway to the current junction of Highways 58 and 99 at the West Bakersfield Interchange, but construction remained controversial since it would displace dozens of homes and businesses[12]; by September 2017 all but a few buildings in the path had been demolished.[13] Once the connection to Highway 99 is completed (which is expected to occur in 2021), Highway 58 will then be rerouted onto Stockdale Highway and the Westside Parkway (and the city transferring the latter's jurisdiction to Caltrans), with further plans to upgrade Stockdale Highway from Heath Road west to Interstate 5 as a freeway.[14]

The San Luis Obispo Planning Commission is considering a permit application for the California Valley Solar Ranch and has released a Draft Environmental Impact Report with a public comment period closure date November 1, 2010. Among the points raised in the DEIR is the aesthetic impact on the viewshed which would be particularly troublesome if large industrial scale arrays of solar panels are placed north of Route 58 in the section of road just east of Soda Lake Road.

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.
