Former California State Route 176

After taking Cat Canyon Road to Palmer Road I took it north to Sisquoc on Foxen Canyon Road which was once the eastern terminus for California State Route 176.






CA 176 was a renumbering of a segment of Legislative Route 148 during the 1964 State Highway Renumbering.  The change from LRN 148 to CA 176 can seen by comparing the 1963 and 1964 State Highway Maps.

LRN 148 actually continued west of US 101 and Santa Maria to Guadalupe at CA 1.  During the 1964 State Highway renumbering the segment of LRN 148 west of US 101 was added as an extension to CA 166.  LRN 148 was adopted in 1933 like much of the current state highway system as cited by CAhighways.org.

Originally when CA 176 was signed ran from US 101 in Santa Maria east on Stowell Road, south on Philbric Road, and southeast on Foxen Canyon Road to the community of Sisquoc.  Betteravia Road and Main Street have often been cited as former routings of LRN 148 and CA 176, however I've found that not to be the true alignment.  On the 1935 California Division of Highways Map of Santa Barbra County LRN 148 can be seen exiting east out of Santa Maria on Stowell Road from Broadway which was US 101 at the time.  Stowell Road, Philbric Road, and Foxen Canyon Road can be identified by the five directional turns it takes to reach the community of Garey which line up with the current roadway alignments.

Update 4/8/18:  I noticed that the old Santa Maria Airport was located on Stowell which is my speculative guess as to why LRN 148 was plotted on it.  More information on the original city airport as well as various vintage city maps of Santa Maria can be found here:

CA 176 is often cited as being deleted in 1984 but it last appears on state highway maps in 1986.  The same five curves that LRN 148 took from Santa Maria to Garey are still present on CA 176 east of US 101.  Interestingly CA 176 is still shown as an active route on modern iPhone devices checking the map data.

On the 1988 State Highway Map CA 176 is no longer present.

In downtown Sisquoc US 101 is still signed at the corner of Foxen Canyon Road and Palmer Road which was eastern terminus of CA 176.  The north route to US 101 is signed at 10 miles which was the approximate length of CA 176.





Sisquoc was located on the Pacific Coast Railroad which is a now defunct narrow-gauge railroad that operated between San Luis Obispo southeast to Los Olivos from 1882 to 1941.  The Pacific Coast line from Santa Maria to Sisquoc was built by 1910 to service an oil refinery in Sisquoc at the recently discovered Cat Canyon Oilfield.  I'm uncertain of when Sisquoc was founded but I did find it on a 1906 map of California before the discovery of oil in Cat Canyon.  Sisquoc still resembles an actual early 20th century town and even has a general store.









CA 176 between Sisquoc and Garey followed the course of the Sisquoc River to the confluence with the Cuyama River.  The Sisquoc River Basin and confluence with the Cuyama River can be seen from Foxen Canyon Road directly north of Sisquoc.  The Sisquoc and Cuyama Rivers converge into the Santa Maria River which flows into the Pacific Ocean.


There is still what appears to be a Caltrans sourced "end 40 MPH" sign exiting Sisquoc westward towards Garey.  Foxen Canyon Road between Sisquoc and Garey is scenic with farm land being broken up by the surrounding hills.  Garey apparently dates back to the late 1880s and was apparently always a center for agriculture.





North of Garey at Santa Maria Mesa Road there is another US 101 sign indicating it is 7 miles away.  There appears to be an older alignment of Foxen Canyon Road and CA 176 that is now barricaded off.






Foxen Canyon Road continues northwest curving through the farm lands and crosses a bridge over a canal.  I didn't get the construction date on the bridge nor could I find it on upon inspecting the Google Car image.








Foxen Canyon Road ends at Philbric Road which is on the right in the photo below.  I wasn't certain about the alignment of CA 176 when I took my pictures so I ended by my album here.  Foxen Canyon Road becomes Betteravia Road ahead in the photo.

History of the Big Oak Flat Road (Yosemite National Park)

This week I hiked much of what was the original alignment of the Big Oak Flat Road which is located to the north of the modern roadway.  Unlike the original alignment of the Wawona Road the Old Big Oak Flat Road is surprisingly intact.


The complete history of the Big Oak Flat Road including the original alignment can be found on a 2002 report from the U.S. Department of Interior on the Old Big Oak Flat Road.

U.S. Department of the Interior on the Old Big Oak Flat Road

The Big Oak Flat Road began construction east from the mining community of Big Oak Flat in towards Yosemite Valley in 1869.  The Big Oak Flat Road was constructed by the Chinese Camp and Yosemite Turnpike Company which had secured the franchise rights for a toll road to the Yosemite Grant (the designation prior to Yosemite National Park).  By the summer of 1871 the Big Oak Flat Road reached the northern cliffs above Yosemite Valley which is when the Chinese Camp and Yosemite Turnpike Company ran out of funding.  After the…

Horseshoe Meadows Road; former California State Route 190 and the legacy of the Lone Pine-Porterville HIgh Sierra Road

This summer I had an opportunity to drive one of the lesser known great roads of California; Horseshoe Meadows Road from Whitney Portal Road westward into Horseshoe Meadows of the Eastern Sierra Nevada Mountains.  Aside from being massive climb into the Eastern Sierra Nevada Mountains the path of Horseshoe Meadows Road was once part of California State Route 190 and was intended to be part of a Trans-Sierra Highway known as the Lone Pine-Porterville High Sierra Road.


Horseshoe Meadows Road is located west of Lone Pine of Inyo County and is 19.7 miles in length.  Horseshoe Meadows Road begins at an approximate elevation of 4,500 feet above sea level at Whitney Portal Road in the Alabama Hills and ends at an elevation of 10,072 feet above sea level in Horseshoe Meadows.  Horseshoe Meadows Road is the second highest paved road in California only behind Rock Creek Road near Tom's Place.  Pjammcycling rates Horseshoe Meadows Road with an average gradient of 6.2% and lists it as th…

The Tioga Pass Road

Last Summer the Tioga Pass Road over the Sierra Nevada Mountains in Yosemite National Park opened late due to the heavy snow pack from the previous winter.  Approaching the start of July the Park Service finally had cleared the road to Tioga Pass.  That being the case I headed up shortly after the 4th of July holiday during a lull in the tourist season.


The Tioga Pass Road runs from the Big Oak Flat Road at Crane Flat east to US Route 395 ("US 395").  The Tioga Pass Road is largely within the boundary of Yosemite National Park but is maintained by Caltrans as California State Route 120 ("CA 120") east of the Tioga Pass entry station to US 395.  The National Park Service maintained portion of the Tioga Pass Road serve as a implied connection between the two segments of CA 120.  The Tioga Pass Road is the highway mountain pass in California reaching Tioga Pass at 9,945 feet above sea level.
