Old California State Route 180 on Dunlap Road

Back in April 2017 I took a detour down the pre-1942 alignment of California State Route 180 on Dunlap Road in far east Fresno County in the Sierra Nevada Range.


Dunlap Road is 13 miles long and connects from modern CA 245 west to CA 180.  At some point between 1940 and 1942 SSR 180 was moved to modern alignment CA 180 takes on the Kings Canyon Highway and SSR 65 was extended north to where the modern northern terminus of CA 245 is now.  The routing for SSR 180 on Dunlap Road and the eventual changes I described can be seen on these maps:

1938 State Highway Map

1940 State Highway Map

1942 State Highway Map


CA 180 would have continued westbound to the right on Dunlap Road in the below picture while CA 65 would have begun on the left.


Dunlap Road is significantly more curvy than the modern Kings Canyon Highway to the north which CA 180 now runs on.  There is some evidence of former state maintenance with culverts that had design origins in the 1930s/40s.



Miramonte is 3 miles west of CA 245.  The community is at an elevation of about 3,000 feet above sea level and was founded some time in the 1900s.  Apparently Miramonte has had a Post Office since 1923.



There was a nice bloom out in the Sierras in last April.  Later in July when I was traveling Dunlap Road I was almost hit head on by a trucker who cut this curve.


There are no marked vistas on Dunlap Road but there is a wide canyon view from the pull-outs.  The modern Kings Canyon Highway can be seen as a cut in the mountains to the north.


Dunlap Road has a ton of steep cliffs but the road is generally plenty wide (unless you're a jackass trying to take a 40 foot plus truck load up it).






The drop on Dunlap Road is far less steep than the Kings Canyon Highway.  Dunlap Road enters the community of Dunlap at about 1,900 feet above sea level.


Apparently Dunlap dates back to the 1880s and was a stage stop.  The area really isn't a "town" per se but does have a school and some other expected services.  Dunlap Road drops a little more elevation before meeting CA 180 at the Kings Canyon Highway.



CA 180 has been a frequent topic of discussion on Gribblenation, the other articles can be found below.

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
