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.

My previous blog where I encountered the path of unbuilt CA 179 can be found here.

Disaster Tourism Road Trip Part 7; The Black Hole of Lake Berryeassa (CA 37, CA 121, CA 128 and unbuilt CA 179)

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.

Morgan Territory Road

Morgan Territory Road is an approximately 14.7-mile-long roadway mostly located in the Diablo Range of Contra Costa County, California.  The roadway is named after settler Jerimah Morgan who established a ranch in the Diablo Range in 1857.  Morgan Territory Road was one of several facilities constructed during the Gold Rush era to serve the ranch holdings.   The East Bay Regional Park District would acquire 930 acres of Morgan Territory in 1975 in an effort to establish a preserve east of Mount Diablo. The preserve has since been expanded to 5,324 acres. The preserve functionally stunts the development along roadway allowing it to remain surprisingly primitive in a major urban area. Part 1; the history of Morgan Territory Road During the period of early period of American Statehood much of the Diablo Range of Contra Costa County was sparsely developed.   Jerimah Morgan acquired 2,000 acres of land east of Mount Diablo in 1856 and established a ranch in 1857. Morgan Territory Road is

Interstate 210 the Foothill Freeway

The combined Interstate 210/California State Route 210 corridor of the Foothill Freeway is approximately 85.31-miles.  The Interstate 210/California State Route 210 corridor begins at Interstate 5 at the northern outskirts of Los Angeles and travels east to Interstate 10 in Redlands of San Bernardino County.  Interstate 210 is presently signed on the 44.9-mile segment of the Foothill Freeway between Interstate 5 and California State Route 57.  California State Route 210 makes up the remaining 40.41 miles of the Foothill Freeway east to Interstate 10.  Interstate 210 is still classified by the Federal Highway Administration as existing on what is now signed as California State Route 57 from San Dimas south to Interstate 10.  The focus of this blog will mostly be on the history of Interstate 210 segment of the Foothill Freeway.   Part 1; the history of Interstate 210 and California State Route 210 Interstate 210 (I-210) was approved as a chargeable Interstate during September of

Clovis "Gateway To The Sierras" sign and Tarpey Depot

Within Oldtown Clovis a fixture of the original alignment of California State Route 168 can be found in the form of the  "Clovis Gateway To The Sierras" sign. The sign was erected along Clovis Avenue in 1940 and was in use along California State Route 168 until the highway was relocated circa 1999-2001. Nearby Tarpey Deport can be found at the northeast corner of Clovis Avenue and 4th Street. The depot was constructed in 1892 as part of the San Joaquin Valley Railroad between Fresno and Friant. The depot structure was one previously located at the southeast corner of Clovis Avenue and Ashlan Avenue. Part 1; the history of the Gateway To The Sierras sign The "Clovis Gateway To The Sierras" sign located in Oldtown Clovis along Clovis Avenue between 4th Street and 5th Street.
