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

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 198 at the bottom of Lake Kaweah

East of Lemon Cove of Tulare County one can find several old alignments of California State Route 198 at the bottom of the Lake Kaweah Reservoir.  In particularly dry years these early alignments of California State Route 198 can be accessed as hiking trails.   Part 1; a brief history of California State Route 198 in the Lake Kaweah Reservoir The current corridor of California State Route 198 ("CA 198") in Lake Kaweah has a lengthy history.  The present corridor around Lake Kaweah first became a popular route of travel for European settlers during the mining boom of Mineral King Valley.   Through the 1860s prospectors arrived in Mineral King Valley by way of the Kaweah River and East Fork Kaweah River.  In 1870 John Lovelace and his family built a stock trail up to what was known as Milk Ranch on the East Fork Kaweah River.  The Lovelace extended their trail all the way up to Mineral King Valley and the prospector camp sites.  In 1871 the stock trail was greatly improved

New River Gorge National River Area To Become A National Park

Great news for those that enjoy National Parks, West Virginia's New River Gorge Region, or West Virginia tourism.  Included within the Fiscal Year 2021 Omnibus Appropriations Bill signed by President Trump last night (December 27th) is the New River Gorge Park and Preserve Designation Act.   The act will designate the existing New River National River and over 72,000 acres of land within it as a National Park and Preserve. The New River Gorge Bridge will continue to be the centerpiece of the new New River Gorge National Park and Preserve. (Adam Prince, 2007) The river and surrounding land, which was added to the National Park System in 1978, will be our 63rd National Park.   The designation preserves over 7,000 acres as a National Park.  This area will not allow any hunting.  The remaining 65,000 acres of the existing park will be designated as a preserve allowing hunting and fishing. The main attractions to the New River Gorge - whitewater rafting, camping, hiking, mountain bikin

Legend of the Ridge Route; a history of crossing the mountains between the Los Angeles Basin and San Joaquin Valley from wagon trails to Interstates

Over the past two decades I've crossed the Interstate 5 corridor from Los Angeles north over the Sierra Pelona Mountains and Tehachapi Range to San Joaquin Valley what seems to be an immeasurable number of times.  While Interstate 5 from Castaic Junction to Grapevine via Tejon Pass today is known to most as "The Grapevine" it occupies a corridor which has been traversed by numerous historic highways.  The most notable of these highways is known as the "Ridge Route."  This article is dedicated to the Ridge Route and the various highways that preceded it.  The Ridge Route is a 44 mile section of highway which was completed in 1915.  The Ridge Route originally stretched from Castaic Junction north over Liebre Summit and Tejon Pass to the tiny community of Grapevine.  In spite of a roadway that once utilized nearly 700 curves the Ridge Route is generally considered far ahead of it's time and one of the first modern highways in California constructed for auto
