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.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l

Mines Road

Mines Road is an approximately twenty-eight-mile highway located in the rural parts of the Diablo Range east of the San Francisco Bay Area.  Mines Road begins in San Antonio Valley in Santa Clara County and terminates at Tesla Road near Livermore of Alameda County.  The highway essentially is a modern overlay of the 1840s Mexican haul trail up Arroyo Mocho known as La Vereda del Monte.  The modern corridor of Mines Road took shape in the early twentieth century following development of San Antonio Valley amid a magnesite mining boom.  Part 1; the history of Mines Road Modern Mines Road partially overlays the historic corridor used by La Vereda del Monte (Mountain Trail).  La Vereda del Monte was part of a remote overland route through the Diablo Range primarily used to drive cattle from Alta California to Sonora.  The trail was most heavily used during the latter days of Alta California during the 1840s. La Vereda del Monte originated at Point of Timber between modern day Byron and Bre

Interstate 210 the Foothill Freeway

The combined Interstate 210/California State Route 210 corridor of the Foothill Freeway is approximately 85.31-miles.  The Interstate 210/California State Route 210 corridor begins at Interstate 5 at the northern outskirts of Los Angeles and travels east to Interstate 10 in Redlands of San Bernardino County.  Interstate 210 is presently signed on the 44.9-mile segment of the Foothill Freeway between Interstate 5 and California State Route 57.  California State Route 210 makes up the remaining 40.41 miles of the Foothill Freeway east to Interstate 10.  Interstate 210 is still classified by the Federal Highway Administration as existing on what is now signed as California State Route 57 from San Dimas south to Interstate 10.  The focus of this blog will mostly be on the history of Interstate 210 segment of the Foothill Freeway.   Part 1; the history of Interstate 210 and California State Route 210 Interstate 210 (I-210) was approved as a chargeable Interstate during September of
