Arizona State Route 51 from Piestewa Peak

Between 2010 to 2013 I lived about half a mile north of the Phoenix Mountains Preserve which allowed me access to the Piestewa Peak Summit Trail.  The Piestewa Peak Summit Trail ascends to the top of 2,610 foot high Piestewa Peak which overlooks the majority of the City of Phoenix and Arizona State Route 51.


The Piestewa Peak Summit Trail off of Squaw Peak Drive in the Phoenix Mountains Preserve.  The Piestewa Peak Trail is a fast 2.2 mile round-trip but ascends 1,151 feet and can be just as difficult as nearby Camelback Mountain.




The view back down the Piestewa Peak Summit Trail from Piestewa Peak really puts into relief how steep it is.


Piestewa Peak is the second highest peak in the Phoenix Mountains after Camelback Mountain.  The mountain was originally known as Squaw Peak as early as 1910 but was renamed to Piestewa Peak in 2003.  The name of Piestewa Peak comes from Lori Piestwa of the U.S. Army and member of the Hopi Tribe.  Lori Piestewa was the first Native American woman to die in combat as member of the U.S. Military.

From Piestewa Peak the entirety of the 16.7 Arizona State Route 51 can be seen traversing through downtown Phoenix at I-10/AZ 202 north through the Phoenix Mountains to AZ 101.





AZ 51 was originally envisioned as part of the original Interstate system as a spur of Interstate 10 north out of downtown Phoenix.  This Interstate Spur was ultimately not included into funding during the original run of Interstates in Arizona but would appear on ADOT logs as I-510 before being changed to AZ 510 in 1968.  The route of AZ 510 was to known as the Squaw Peak Freeway.


Oddly the first five miles of AZ 510 north of I-10 to Glendale Avenue were constructed by the City of Phoenix between 1986 and 1991.  In 1987 the route number of AZ 510 was changed to the current designation of AZ 51.  In 1992 the original five miles of AZ 51 was turned over to ADOT for maintenance which in turn reconstructed it to state standards in 2003.  AZ 51 was completed from Bell Road north to AZ 101 in May of 2003 and I actually recall driving it the week after it had opened.  2003 also saw the Squaw Peak Parkway name changed to Piestawa Peak Parkway to reflect the renaming of Piestewa Peak.

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? 

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. 

Closing the Gap - How Interstate 77 in North Carolina and Virginia Came To Be

Interstate 77 through the Virginias and Carolinas was not an original Interstate Highway proposal.  In 1957, Interstate 77 was born as an over 400-mile southwards extension of a previously approved Cleveland to Canton, Ohio Interstate.  The new road would extend through four states before terminating at Interstate 85 near Charlotte, North Carolina.  This extension would bring an additional north-south highway connecting the industrial Midwest to the South.   During the early planning stages of Interstate 77 from the late 1950s through the mid-1960s, North Carolina and Virginia had different plans routing the Interstate that took over five years to settle. While the new Ohio to Charlotte Interstate would follow the WV Turnpike to its terminus at US 460 near Princeton, its route through the remainder of West Virginia, Virginia, and North Carolina was uncertain.  The route south from Princeton into Virginia and to Interstate 81 near Wytheville consisted of two options.  An eastern option
