California State Route 371

This past October I drove the entirety of California State Route 371 from CA 79 northeast to CA 74.


CA 371 is a 21 mile east/west State Highway which serves as a connector between CA 79 and CA 74.  CA 371 is entirely located within Riverside County.



Part 1; the history of California State Route 371

The current alignment that is now CA 371 was added to the State Highway System in 1959 as Legislative Route 277 according to CAhighways.  The planned alignment of LRN 277 first appears on the 1960 Division of Highways State Map.  Cahuilla Road and Kenworthy-Bautista Road are shown to be more or less the existing through route.


It appears that instead of building a new alignment for LRN 277 the Division of Highways opted to assume maintenance of Cahuilla Road and Kenworthy-Bautista Road.  LRN 277 can be seen aligned over Cahuilla Road and Kenworthy-Bautista Road on the 1962 Division of Highways State Map.


During the 1964 State Highway Renumbering LRN 277 was reassigned as an eastern extension of CA 71.  The new assignment of CA 71 over what was LRN 277 can be seen on the 1964 Division of Highways Map.


According to CAhighways CA 71 was truncated in 1974 to I-15 near Murrieta.  This truncation led to CA 71 between CA 79 and CA 74 being reassigned as CA 371.  CA 371 can be seen for the first time on the 1975 Caltrans State Highway Map.   CA 371 as an assigned number was a simple adding of a "3" to the previous CA 71 designation. 



Part 2; a drive on California State Route 371

My approach to CA 371 eastbound was from CA 79 southbound.  CA 371 is signed as a cut-off road to Indio.







Interestingly Post Mileage on CA 371 begins at RIV 56.469 which is a trace vestige of the previous CA 71 designation.  CA 371 eastbound is immediately signed as a Daytime Headlight Safety Corridor for the next 18 miles.  Truck traffic on CA 371 is advised against 30 foot or longer loads.  Traffic is further advised that CA 371 is susceptible to chain restrictions.





Anza is signed as 14 miles away on CA 371 east.  Palm Desert is signed as 43 miles away and Indio is signed at 53 miles.


CA 371 eastbound traverses the semi-arid terrain of the Santa Rosa Mountain foothills and enters the Cahuila Indian Reservation at Post Mile RIV 67.145.



















CA 371 east passes through the Cahuila Reservation and enters the community of Anza.






Anza lies at an elevation of 3,921 feet above sea level in Anza Valley.  The community of Anza is named after Spanish explorer Juan Bautista de Anza which explored Anza Valley in 1774 and 1775.  CA 371 passes through Anza on Cahuilla Road where it transitions onto Kenworthy-Bautista Road.












CA 371 east of Anza begins to ascend into the Santa Rosa Mountains, traffic is advised the Safety Corridor ceases.





CA 371 east enters San Bernardino National Forest at Post Mile RIV 75.264.  CA 371 ascends through the Santa Rosa Mountains to an east terminus  at CA 74/Pines-to-Palms Highway at Post Mile RIV 77.143.

Suggest edit/addition at end of first paragraph:
It is part of an east-west corridor formed by parts of California 79, California 371, and California 74 between Temecula and the Palm Springs-Coachella Valley area.The same east-west corridor serves as a popular short cut for motorists traveling between San Diego County and Palm Springs-Coachella Valley regions for the spectacular scenery and shorter distance (by 25 miles) versus the heavily congested freeway route via Interstates 10, 15 and 215.

The history of US Route 80 and Interstate 8 in California

The historic corridor of US Route 80 and Interstate 8 through the borderlands of southern California share a largely mutual history.  Both highways originated in the city of San Diego and departed the state at the Colorado River into Yuma, Arizona.  Both highways share numerous famous geographical components such as the Mountain Springs Grade and Algodones Sand Dunes.  This article serves as a comprehensive history of the combined US Route 80/Interstate 8 corridor in California from the tolled stage route era of the nineteenth century to the development of the modern freeway.   The blog cover photo features US Route 80 along the Mountains Springs Grade through In-Ko-Pah Gorge during late 1920s.  This photo is part of the Caltrans McCurry Collection.

The Central Freeway of San Francisco (US Route 101)

The Central Freeway is a 1.2-mile elevated limited access corridor in the city of San Francisco.  As presently configured the Central Freeway connects from the end of the Bayshore Freeway to Market Street.  The Central Freeway carries the mainline of northbound US Route 101 from the Bayshore Freeway to Mission Street. The Central Freeway has origins with the establishment of Legislative Route Number 223 and is heavily tied to the history of the once proposed Panhandle Freeway.  The Central Freeway between the Bayshore Freeway and Mission Street was completed during 1955.  The corridor was extended to a one-way couplet located at Turk Street and Golden Gate Avenue in 1959 which served to connect US Route 101 to Van Ness Avenue.  The Central Freeway was damaged by the 1989 Loma Prieta Earthquake and has since been truncated to Market Street.   The Central Freeway as pictured on the blog cover was featured in the May/June 1959 California Highways & Public Works.  The scan below is fro

The Midway Palm and Pine of US Route 99

Along modern day California State Route 99 south of Avenue 11 just outside the City limits of Madera one can find the Midway Palm and Pine in the center median of the freeway.  The Midway Palm and Pine denotes the halfway point between the Mexican Border and Oregon State Line on what was US Route 99.  The Midway Palm is intended to represent Southern California whereas the Midway Pine is intended to represent Northern California.  Pictured above the Midway Palm and Pine can be seen from the northbound lanes of the California State Route 99 Freeway.   This blog is part of the larger Gribblenation US Route 99 Page.  For more information pertaining to the other various segments of US Route 99 and it's three-digit child routes check out the link the below.
