Nevada State Route 431; the Mount Rose Highway

Back in 2016 I had a chance to drive Nevada State Route 431 from NV 28 at Lake Tahoe northeast to US 395A/NV 341 south of Reno.






NV 431 is a 24.4 mile State Highway and as the sign above states is reputed to be the highest all-year pass in the Sierra Nevada Range at 8,911 feet above sea level.  The Mount Rose Highway has been a Signed State Highway for a long time first appearing on the Nevada State Highway Map in 1932 as NV 27.

Unlike nearby NV 28 the numbering of NV 27 was reassigned to NV 431 in 1976 during the Nevada State Highway renumbering.  The new designation of NV 431 appears alongside NV 27 on the Mount Rose Highway on the 1978 Nevada State Highway Map.

NV 431 starts eastward from NV 28 on the northeast shore of Lake Tahoe in Incline Village at approximately 6,350 feet above sea level.


From Incline Village NV 431 begins to ascend quickly and has a massive vista of Lake Tahoe at the first major hairpin.


NV 431 quickly rises to the 8,911 feet Mount Rose Summit.


Truckee Meadows can be seen ahead from Mount Rose northeast on NV 431.


From Mount Rose NV 431 begins to descend rapidly crossing through the Mount Rose Ski Area.  NV431 has a minor unsigned junction at NV 878/Slide Mountain Ski Bowl Highway.


The rapid descent of NV 431 to Truckee Meadows continues through a large number of wide switchbacks before straightening out on a steep descent.


NV 431 has a junction with US 395/I-580 before terminating at the junction of NV 341/US 395A.

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

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
