Los Gatos Creek Road/Coalinga Road

In late December of 2016 I was traveling through the Diablo Range and wanted to try Los Gatos Creek Road/Coalinga Road as an alternate to CA 198.

I started the day out with taking CA 198 to the 33 junction north of Coalinga. From there I took Shell Road, Oil City Road, Palmer Avenue, and Derrick Avenue to reach Los Gatos Creek Road.

As a singular route Los Gatos Creek Road and Coalinga Road are a roughly 46 miles in crossing the Diablo Range to CA 25 just north of Bitterwater in San Benito County.

The Fresno side of the route is signed as Los Gatos Creek Road and the San Benito side is Coalinga Road.

The entire route through the Diablos is paved. The Fresno County side is pretty high quality with a center stripe the entire way along with a very gradual grade up to the the Condon Peak recreation area and San Benito County.

After crossing into San Benito County the route becomes Coalinga Road and is a single wide lane with no center stripe. I should note that it was about 20F outside when I made this trip and the shaded areas of the roadway in San Benito County were largely frost covered.

Interestingly between Coalinga and the Clear Creek Management Area there are plenty of ranch homes or at least just as many if not more than CA 198 to the south. The Clear Creek Management Area has naturally occurring asbestos fibers which are actually hazardous to travel in during the dry summer months. .Areas north of the Clear Creek Management Area have additional hazards from the New Idria Mercury Mine which is a ghost town and Super Fund site.

Despite Coalinga Road being narrow I didn't really have much issues with surface quality aside from the couple miles between the Clear Creek Management Area and Hernandez Reservoir. Essentially the issue wasn't so much the asphalt quality but rather surface ice/frost on the road and a large quantity of rock fall. Coalinga Road has a very steep uphill grade westbound past the Hernandez Reservoir up to the Laguna Mountain Recreation Area.

The Hernandez Dam is a pretty interesting topic to me. NE2 from AAroads shared a 1939 State Highway Map showing that there was a populated place called "Hernandez" where the reservoir is now. Apparently the reservoir was built in the 1960s to impound the San Benito River and Hernandez disappeared off the State Highway Maps by 1967. Hernandez wasn't shown in the 1896 San Benito County Map but is present on the State Highway Map in 1918. Its strange that I can't find any mention of Hernandez anywhere on the web but that seems to be the case with almost every previously populated place in San Benito County aside from New Idria. Regardless here is links to the previously mentioned maps:

I was able to find this transformer box with "Hernandez Dam" near the Laguna Mountain Campground.

Coalinga Road gets keeps getting more windy and even fords a creek up to about 3,000 feet above sea level at Laguna Mountain.

Laguna Mountain has some fantastic views of the Diablo Range. I'm to understand the peak is 4,462 feet above sea level.

Coalinga Road sharply descends from Laguna Mountain through Miller Canyon where there is some sharp hair pin curves.

Coalinga Road levels out onto a placid valley filled with ranch lands.

The 1939 Map showed that the previous alignment of Coalinga Road used what is now Old Hernandez Road. Old Hernandez is closed off now but popped out to the northwest at San Benito at CA 25.

West of Old Hernandez Road, Coalinga Road becomes a two-lane road again all the way to CA 25.

Where the hell is Hill Valley? (US Route 8 south/US Route 395 east)

Recently I made a visit to Universal Studios near Los Angeles. While on the back lot tour I came across a piece of infamous movie-borne fictional highway infamy; the location of town square of Hill Valley, California on US Route 8/US Route 395. The above photo is part of the intro scene to the first Back-to-the-Future movie which was set in 1985. To anyone who follows roadways the signage error of US 8 meeting US 395 in California is an immediately notable error. For one; US 8 doesn't even exist anywhere near California with present alignment being signed as an east/west highway between Norway, Michigan and Forest Lake, Minnesota. To make matters worse US 8 is signed as a southbound route and US 395 (a north/south highway) is signed as an eastbound route. At minimum the cut-out US 8 and US 395 shields somewhat resemble what Caltrans used in the 1980s. Assuming Hill Valley is located on what would have been US 395 by 1985 what locales would be a viable real world analog?

The Vague Original Southern Terminus of US Route 91 in the Californian Mojave Desert

One of the more intriguing mysteries of the early US Route System in California is where the original south terminus of US Route 91 was intended to be located in the Mojave Desert. This blog is a little different than my usual behind the wheel fare and explores why US Route 91 ultimately ended at US Route 66 in Daggett instead of Bannock. What ultimately became the US Route System was first discussed during the American Association of State Highway Officials ("AASHO") during their annual 1924 meeting. Ultimately the AASHO recommended to the Department of Agriculture to work with the States to develop a system of Interstate Highways to replace the many Auto Trails in use. The Joint Board on Interstate Highways was ultimately commissioned by the Department of Agriculture and it's branch agency the Bureau of Public Roads in March of 1925. The Joint Board on Interstate Highways first met in April of 1925 and decided on the new interstate road network would be known a

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 constructed for automotive use.
