Unbuilt California State Route 179

Back in 2017 I spent a good deal of time driving scenic highways located in Marin, Napa, Sonoma Yolo and Solano Counties.  While heading east from Lake Berryessa through the Vaca Mountains California State Route 128 I took a turn on Pleasant Valley Road south towards Vacaville.  What I stumbled upon was the unbuilt California State Route 179 on a very aptly named Pleasant Valley Road.  This year after traversing the Bay Area I decided to revisit the unbuilt CA 179.


CA 179 was intended to be a 14 mile north/south State Highway between CA 128 in Yolo County and Interstate 80 in Solano County.  The route of CA 179 while unbuilt has a traversable route over Pleasant Valley Road and Cherry Glen Road.  CA 179 was approved as LRN 244 in 1959 by the State Legislature according to CAhighways.org.

The implied path of LRN 244 first appears on the State Highway Map on 1960.

During the 1964 State Highway renumbering the route of LRN 244 was reassigned as CA 179.  The change from LRN 244 to CA 179 can be seen by comparing the 1963 State Highway Map to the 1964 Edition.

I started my journey on the path of Unbuilt CA 179 in Yolo County from CA 128 west where I turned south on Pleasant Valley Road.


Pleasant Valley Road south crosses Putah Creek and Lake Solano to the Solano County line.




Lake Solano was created when Putah Division Dam was completed in 1957.  Suffice to say the change of character from the upstream division on Putah Creek at Monticello Dam is quite quaint by comparison.



Pleasant Valley Road has a somewhat significant junction with Putah Creek Road south of Lake Solano.  Vacaville is signed as being 13 miles to the south.



Most of Pleasant Valley Road is signed at 45 MPH and despite the low elevations is very curvy.




Pleasant Valley Road winds through the terrain which has some highly scenic views of the local farms and low parts of the Vaca Range.









At Miller Canyon Creek the route of Pleasant Valley Road is routed of the one-lane Edward R. Thurber Bridge.



The Thurber Bridge is a concrete arch bridge which was completed in 1907.   The Thurber Bridge is highly scenic and definitely a huge change of pace from the mega-urban-super-freeways I had been driving much of the day earlier in the Bay Area.  Traffic over the Thurber Bridge is controlled by two simple Stop signs.



Pleasant Valley Road south of the Thurber Bridge continues to wind through the hills all the way to Cherry Glen Road.















Cherry Glen Road connects to I-80 at Exits 51A and 51B.  It isn't really clear where CA 179 was meant to connect to so I turned east towards Vacaville and I-80 Exit 51B.

I-40 rockslide uncovers old debates on highway

The Asheville Citizen-Times continues to do a great job covering all the angles of the Interstate 40 Haywood County rock slide. An article in Sunday's edition provides a strong historical perspective on how the Pigeon River routing of Interstate 40 came about. And perhaps most strikingly, in an article that ran just prior to the highway's opening in the fall of 1968, how engineers from both Tennessee and North Carolina warned "...that slides would probably be a major problem along the route for many years." On February 12, 1969, not long after the Interstate opened, the first rock slide that would close I-40 occurred. Like many other Interstates within North Carolina, Interstate 40 through the mountains has a history prior to formation of the Interstate Highway System and was also a heated political battle between local communities. The discussion for a road that would eventually become Interstate 40 dates back to the 1940's as the idea for interregional high

Mines Road

Mines Road is an approximately twenty-eight-mile highway located in the rural parts of the Diablo Range east of the San Francisco Bay Area.  Mines Road begins in San Antonio Valley in Santa Clara County and terminates at Tesla Road near Livermore of Alameda County.  The highway essentially is a modern overlay of the 1840s Mexican haul trail up Arroyo Mocho known as La Vereda del Monte.  The modern corridor of Mines Road took shape in the early twentieth century following development of San Antonio Valley amid a magnesite mining boom.  Part 1; the history of Mines Road Modern Mines Road partially overlays the historic corridor used by La Vereda del Monte (Mountain Trail).  La Vereda del Monte was part of a remote overland route through the Diablo Range primarily used to drive cattle from Alta California to Sonora.  The trail was most heavily used during the latter days of Alta California during the 1840s. La Vereda del Monte originated at Point of Timber between modern day Byron and Bre

Former California State Route 41 past Bates Station

When California State Route 41 was commissioned during August 1934 it was aligned along the then existing Fresno-Yosemite Road north of the San Joaquin River.  Within the Sierra Nevada foothills of Madera County, the original highway alignment ran past Bates Station via what is now Madera County Road 209, part of eastern Road 406 and Road 207.   Bates Station was a stage station plotted during the early 1880s at what was the intersection of the Coarsegold Road and Stockton-Los Angeles Road.   The modern alignment bypassing Bates Station to the east would be reopened to traffic during late 1939.   Part 1; the history of California State Route 41 past Bates Station Bates Station was featured as one of the many 1875-1899 Madera County era towns in the May 21, 1968, Madera Tribune .  Post Office Service at Bates Station is noted to have been established on November 23, 1883 and ran continuously until October 31, 1903.  The postal name was sourced from Bates Station owner/operator George Ba
