California State Route 153; The Supposedly Shortest State Highway

I mentioned California State Route 153 in El Dorado County on the CA 49 blog but I thought it was worth it's own blog entry considering the boast made on the placard about it being the "Shortest" state highway in California.


CA 153 is a 0.544 mile route from CA 49 near Coloma to the James Marshall Monument in Marshall Gold Discovery State Historic Park.


CA 153 being the the "Shortest State Highway" certainly isn't true as CA 225, CA 275, CA 283 and CA 77 are actually shorter. 

CAhighways.org list of shortest state highways

CA 153 isn't even technically the shortest signed State Highway as CA 77 is presently signed at only 0.45 miles..  But with that said, CA 153 isn't signed particularly well as there is nothing to indicate there is an actual highway junction at CA 49 at the beginning of the route at Cold Springs Road.  CA 153 begins on the left in the pictures below.



CA 153 turns off of Cold Springs Road on to Monument Road on the right in the picture below.  Again, there is no indication that CA 153 actually exists due to the lack of signage.


Even most of Monument Road lacks any real indication that you're on CA 153.


Which changes with this lone CA 153 shield which might be the rarest ever posted in California.



CA 153 ends at the Marshall Monument which is dedicated to the finding of gold in the waters of the South Fork American River which spurred the 1849 California Gold Rush.  CA 153 was a 1964 renumbering of Legislative Route Number 92 which was adopted which was adopted in 1933.

The change from LRN 92 to CA 153 actually is observable on the 1963 and 1964 State Highway Maps.



It appears that at least up until the 1990s CA 153 wasn't actually signed in the field.  The shield must have been a rogue placement by Caltrans District 3 as CA 153 isn't shown as signed on the 1990 State Highway Map



The 1935 California Division of Highways Map of El Dorado County actually shows LRN 92 branching off from CA 49 to Marshall's Monument.

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

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

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
