Road 222/Powerhouse Road

Last Memorial Day I took a trip up to Glacier Point in Yosemite.  Given the large crowds heading to/from Yosemite National Park I decided to do something a little unconventional and take Road 222/Powerhouse Road over the San Joaquin River to reach Fresno.






Road 222/Powerhouse Road is an approximately 14 mile route between North Fork in Madera County and Auberry in Fresno County.  Road 222 begins at North Fork Road/Road 222 immediately south of North Fork.





Road 222 southbound to the San Joaquin River at Kerckhoff Lake has a heavy grade that is as high as 9% in places.  The road is generally pretty good but drops from about 3,300 feet above sea level to about 1,300 feet above sea level at the San Joaquin River.











Road 222 approaches Kerckhoff Lake and the Wishon Powerhouse.  Kerckhoff Lake is impounded from the waters of the San Joaquin River and is part of Pacific Gas & Electricity's Big Creek project. Apparently Kerckhoff Dam was completed in 1920.







I'm not sure where this stairwell goes but it was across Road 222 from the Wishon Powerhouse, I thought it looked cool.





Road 222 becomes Powerhouse Road on this bridge as it enters Fresno County.







The climb south on Powerhouse Road to Auberry Road and Auberry isn't as steep as Road 222 but far more curvy.  Powerhouse Road ends at Auberry Road in the community of Auberry.









Given that Kerckhoff Lake was part of the Big Creek Project both Road 222 and Powerhouse Road are quiet old.  Both roads are observable as being county maintained on the 1935 California Division of Highways maps of Madera and Fresno Counties.

The Temperance Flat Dam Project has been floated around for about a decade from what I can recall.  If the Temperance Flat Dam Project was ever approved it encompass Kerckhoff Lake within it's catchment area.  The Temperance Flat Dam is heavily supported by Fresno County farmers due to the Big Creek Project being primarily used for Hydroelectric Power rather than water storage.  The Temperance Flat Dam project really seems to not have gained much traction other than being San Joaquin ranch community argument point against the High Speed Rail project.  I found a FAQ on the Temperance Flat Dam Project from the Department of Water Resources but it is over a decade old.

Petroleum Club Road (former California State Route 33 and US Route 399 past the Lakeview Gusher)

Petroleum Club Road is an approximately 5.3-mile rural highway located in the Sunset Oil Field of western Kern County.  This corridor was constructed as a frontage road of the Sunset Railroad and would be the site of the Lakeview Gusher in 1910.  Petroleum Club Road was the original alignment of California State Route 33 and US Route 399 between 1934-1938.  In 1938 the West Side Highway was constructed west of Lakeview Gusher and still serves as the current alignment of California State Route 33.   Part 1; the history of Petroleum Club Road Petroleum Club Road is the original highway which linked the oil communities of Maricopa and Taft.  Both cities were developed around the early boom of the Sunset Oil Field.  The early Sunset Oil Field can be seen centered along Cienega Canyon Road southwest of Buena Vista Lake in Township 11 North, Range 23 West on the 1898 Kern County Surveyors map .  In 1901 Post Office Service would be established at the Su...

Kuakini Highway (former Hawaii Route 11 in Kailua-Kona)

Kuakini Highway east of Palani Road in Kailua-Kona is the original alignment of Hawaii Route 11.  The highway upon being commissioned in 1955 began at the Palani Road (then Hawaii Route 19) and followed Kuakini Highway southeast towards Holualoa.  Hawaii Route 11 was shifted to an extension of Queen Kaahumanu Highway during the late 1970s which bypassed downtown Kailua-Kona.   This page is part of the Gribblenation Hawaii Roads series.  A compellation of all Hawaii-related media from both Gribblenation and RoadwayWiz can be found by clicking  here .  Part 1; the history of Hawaii Route 11 and Kuakini Highway in Kailua-Kona Hawaii Route 11 is part of Mamalahoa Highway (the Hawaii Belt Road) and is the longest Hawaiian State Route at 121.97 miles.  The highway begins at the mutual junction of Hawaii Route 19 and Hawaii Route 190 in Kailua-Kona.  From Kailua-Kona the routing of Hawaii Route 11 crosses the volcanic landscapes of southern side of ...

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...
