National Park Wednesday; Maricopa Road through Sonoran Desert National Monument to Arizona State Route 238

Back between 2010 and 2012 I frequently traveled through Sonoran Desert National Monument on Maricopa from Gila Bend to Arizona State 238 in Mobile.






The route between AZ 347 in Maricopa in Pinal County east to AZ 85 in Maricopa County is 44.27 miles in length.  Despite the current Maricopa Road being quite good and a solid shortcut from Phoenix to Yuma only the first 20.27 miles west from AZ 347 is state maintained as AZ 238.  AZ 238 ends slightly west of the Pinal County Line and Mobile but continues as the paved county maintained road another 24 miles to AZ 85 in Gila Bend.  Much of Maricopa Road from the west terminus of AZ 238 to AZ 85 traverses the Sonoran Desert National Monument along a Southern Pacific Line between the North Maricopa Mountains and South Maricopa Mountains.  The photos below are from Maricopa County just east of Gila Bend in the Sonoran Desert National Monument between the twin Maricopa Ranges.




AZ 238 is a recent addition to the Arizona State Highway system having been created in 1986.  AZ 238 was meant to serve a hazardous waste station in the community of Mobile which was ultimately never built.  AZ 238 is mostly signed on Maricopa Road but a small portion is signed on Smith Enke Road within in the City of Maricopa.  While AZ 238 was paved relatively quickly it wasn't until some point between 1996 and 2001 that Maricopa Road was paved all the way west to Gila Bend. 

Sonoran Desert National Monument lies within a fairly undeveloped part of Sonoran Desert south of the Phoenix Area.  Sonoran Desert National Monument extends south of I-8 into the Table Top Wilderness and is managed by the Bureau of Land Management.  Sonoran Desert National Monument was declared in 2001 but it is largely thought that it was created to impede the southern sprawl of Metro Phoenix.

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...

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.   ...

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 ...
