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 Daylight Headline 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.

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n

Former US Route 101 and California State Route 1 in San Luis Obispo

Originally US Route 101 upon descending Cuesta Pass southbound entered the City of San Luis Obispo via Monterey Street.  From Monterey Street US Route 101 utilized Santa Rosa Street and Higuera Street southbound through downtown San Luis Obispo.  Upon departing downtown San Luis Obispo US Route 101 would have stayed on Higuera Street southward towards Pismo Beach and Arroyo Grande.  Notably; beginning in 1934 US Route 101 picked up California State Route 1 at the intersection of Monterey Street/Santa Rosa Street where the two would multiplex to Pismo Beach.  Pictured below is the 1 935 Division of Highways Map of San Luis Obispo County depicting the original alignments of US Route 101 and California State Route 1 in the City of San Luis Obispo.   Part 1; the history of US Route 1 and California State Route 1 in San Luis Obispo San Luis Obispo lies at the bottom of the Cuesta Pass (also known as the Cuesta Grade) which has made it favored corridor of travel for centuries.  Cuesta Pass

Former California State Route 1 over Old Pedro Mountain Road

California State Route 1 in western San Mateo County traverses the Montara Mountain spur of the Santa Cruz Mountains.  In modern times California State Route 1 passes through Montara Mountain via the Tom Lantos Tunnels and the highway is traditionally associated with Devils Slide.  Although Devils Slide carries an infamous legacy due it being prone landslides it pales in comparison to the alignment California State Route 1 carried prior to November 1937 over Old Pedro Mountain Road.   Old Pedro Mountain Road opened to traffic in 1915 and is considered one of the first major asphalted highways in California.  Old Pedro Mountain Road clambers over a grade from Montara towards Pacifica via the 922 foot high Saddle Pass.  Pictured above an overlook of Old Pedro Mountain Road facing southward towards Montara as it appears today.  Pictured below it the same view during June 1937 when it was part of the original alignment of California State Route 1.  Today Old Pedro Mountain sits abandoned a
