Challenger Adventures in the Coast Range Part 4; California State Route 198 between US 101 and I-5

The last leg of the Challenger road trip was along one of the best driving roads in the state; California State Route 198 between US 101 east to I-5.


CA 198 in present configuration is a 141 mile east/west State Highway from US Route 101 in San Lucas of Monterey County east to the Generals Highway or Sequoia National Park in Tulare County.


CA 198 was one of the original Signed State Highways which was announced in a 1934 Department of Public Works Guide on Page 32.  CA 198 was aligned entirely over Legislative Route 10.  Originally CA 198 was the highest number assigned to any Signed State Highway.


Legislative Route 10 ("LRN 10") was first added to the State Highway System in 1909 during the First State Highway Bond act as a route between Goshen and Hanford.  LRN 10 was extended west to San Lucas by the State Legislature in 1915 and east to Sequoia National Park during the 1919 Third State Highway Bond Act.  More details can be found on CAhighway.org on the LRN 10 Page.

CA 198 starts at US 101 in San Lucas which dates back to the mid-1880s as a railroad siding along the Southern Pacific.  US 101 before it was a freeway used to run on Cattleman Road and thus the western terminus of CA 198 was up ahead in the below picture.


Between San Lucas and Coalinga there is no services along CA 198 for 53 miles.  CA 198 passes through the Gabilan Range, Diablo Range, and Kettleman Hills traveling east from US 101 to I-5.


It wasn't windy out but for some reason the king of all tumbleweed was on the road.


CA 198 gradually ascends through the Gabilans to an approximate elevation of about 1,200 feet before reaching a 5% grade descent into Peach Tree Valley.








Peach Tree Valley is where the southern terminus of CA 25 intersects CA 198.  To the south Peach Tree Valley Road continues southward towards San Luis Obispo County and Paso Robles.  Peach Tree Valley is notable in that the San Andreas Fault is located in it.





Peach Tree Valley is the boundary line between the Gabilan Range on the Pacific Plat to the west and the Diablo Range to the east on the North American Plate.  The roadway looking into the Diablos from Peach Tree Valley looks like it goes on forever and has a 7% grade.


On the way up the Diablo Range there is a couple really wide views of the San Andreas Fault in Peach Tree Valley that can be seen above 2,000 feet.  The Gabilan Range, Salinas Valley, Santa Lucia Range, and even on a really clear day sometimes the Pacific can be seen.  I prefer the make-shift overlook on a volcanic rock with an Illuminati symbol tagged on it.







CA 198 tops out at about 2,700 feet above Lewis Creek.  This year picked this segment of CA 198 as part of the Best Driver's car test.  The roadway is sweeping but easily be held at the 55 MPH speed limit in the hands of a good driver.




This gate was once the southern terminus of CA 25 on Lewis Creek Road until the 1950s.  But rather than go through the history of CA 25 I'll refer to the blog on topic where I talked about it in much more detail.




The only community between San Lucas and Coalinga is Priest Valley.  I have no idea when Priest Valley was created but the ranch homes appear to be from the late 1800s.




At the far eastern end of Priest Valley CA 198 leaves Monterey County and enters Fresno County.



After descending through a small canyon in Fresno County CA 198 enters another valley and approaches a junction with Coalinga Mineral Springs Road.


 

East of Coalinga Mineral Springs Road CA 198 begins to lose elevation rapidly approaching the Parkfield Grade.  The Parkfield Grade is a high ridge road which begins a dirt surfaced highway in San Luis Obispo County that reaches the community of Parkfield.  Really the Parkfield Grade a hell of a pretty drive and I have it on my back list of road blogs to put on this site.




East of the Parkfield Grade CA 198 enters a series of Canyons which empty out into the city of Coalinga.  The road here is a lot of fun, especially if you don't have any truckers or cars ahead of you.










CA 33 intersects CA 198 in Coalinga and multiplexes it north out of the city.  Coalinga was established as a Southern Pacific Railroad siding in 1888 when it was called Coaling Station A.  Apparently "Coalinga" comes from combing the "Coaling" and "A" from the previous status a railroad siding.


CA 198/33 climb into the Kettleman Hills where CA 198 continues east towards I-5.  This section of roadway was just repaved this year, I originally was going to continue on CA 33 but there was a flag zone with oil trucks heading towards it.




Really there isn't much point in showing maps from CA 198 between US 101 and I-5 since the road alignments are nearly identical to back to 1934.  All of CA 198 was previously Legislative Route 10 which was adopted in stages starting in 1909.

Something notable I did encounter on the way home was trying to get around CA 145 near Kerman.  I mentioned this in an earlier blog but there has been random shootings on CA 145 between Kerman and Madera.  The shootings have occurred either in the morning or evening commutes and have been random caliper gun fire.  The sixth shooting occurred the day I was traveling back but I didn't know it was on Dickenson Avenue which just so happened to be the route I took bypass Kerman.  Nothing weird happened on the way home but it was very apparent Fresno County Sheriff was looking for the shooter given how many officers were on the road.

The Dummy Lights of New York

  A relic of the early days of motoring, dummy lights were traffic lights  that  were  placed  in the middle of a street intersection. In those early days, traffic shuffled through busy intersections with the help of a police officer who stood on top of a pedestal. As technology improved and electric traffic signals became commonplace, they were also  originally  positioned on a platform at the center of the intersection. Those traffic signals became known as  " dummy lights "  and were common until  traffic lights were moved  onto wires and poles that crossed above the intersection.  In New York State, only a handful of these dummy lights exist. The dummy lights  are found  in the Hudson Valley towns of Beacon and Croton-on-Hudson, plus there is an ongoing tug of war in Canajoharie in the Mohawk Valley, where their dummy light has been knocked down and replaced a few times. The dummy light in Canajoharie is currently out of commission, but popular demand has caused the dummy

Former US Route 101 and California State Route 41 through Paso Robles

Paso Robles is a city located on the Salinas River of San Luis Obispo County, California.  As originally configured the surface alignments of US Route 101 and California State Route 41 converged in downtown Paso Robles.  US Route 101 originally was aligned through Paso Robles via Spring Street.  California State Route 41 entered the City of Paso Robles via Union Road and 13th Street where it intersected US Route 101 at Spring Street.  US Route 101 and California State Route 41 departed Paso Robles southbound via a multiplex which split near Templeton.   Pictured above is the cover of the September/October 1957 California Highways & Public Works which features construction of the Paso Robles Bypass.  Pictured below is the 1935 Division of Highways Map of San Luis Obispo County which depicts US Route 101 and California State Route 41 intersecting in downtown Paso Robles.   Part 1; the history of US Route 101 and California State Route 41 in Paso Robles Paso Robles ("Pass of the

Colorado Road (Fresno County)

Colorado Road is a rural highway located in San Joaquin Valley of western Fresno County.  Colorado Road services the city of San Joaquin in addition the unincorporated communities of Helm and Tranquility.  Colorado Road was constructed between 1910 and 1912 as a frontage road of the Hanford & Summit Lake Railway.  The roadway begins at California State Route 145 near Helm and terminates to the west at James Road in Tranquility.   Part 1; the history of Colorado Road Colorado Road was constructed as frontage road connecting the sidings of the Hanford & Summit Lake Railway.  The Hanford & Summit Lake Railway spanned from South Pacific Railroad West Side Line at Ingle junction southeast to the Coalinga Branch at Armona.  The Hanford & Summit Lake Railway broke ground during August 1910 and was complete by April 1912. The Hanford & Summit Lake Railway established numerous new sidings.  From Ingle the sidings of the line were Tranquility, Graham, San Joaquin, Caldwell, H
