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.

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.
