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.

Grand Loop Road of Yellowstone National Park

  Grand Loop Road is a 140 mile loop highway which traverses the interior of Yellowstone National Park.  Grand Loop Road connects all of the major attractions and geological features of Yellowstone National Park along with the entrance roads.  Grand Loop Road is a seasonal highway and despite some conjecture never has been part of the US Route System.   Part 1; the history of Grand Loop Road The majority of history pertaining to Grand Loop Road was taken from the below National Park Service article: Historic Roads - Yellowstone National Park (U.S. National Park Service) (nps.gov) Yellowstone was declared the first National Park of the United States on March 1st, 1872.  The first real highway to access Yellowstone National Park came in 1873 when a tolled facility was constructed from Bozeman, Montana via Yankee Jim Canyon to Mammoth Hot Springs.  Numerous attempts were made to fund construction of roadway infrastructure during the early years of Yellows...

The last 1956-63 era California Sign State Route Spade?

Along southbound California State Route 170 (the Hollywood Freeway Extension) approaching the Hollywood Freeway/Ventura Freeway interchange a white California State Route 134 Sign State Route Spade can be observed on guide sign.  These white spades were specifically used during the 1956-63 era and have become increasingly rare.  This blog is intended to serve as a brief history of the Sign State Route Spade.  We also ask you as the reader, is this last 1956-63 era Sign State Route Spade or do you know of others?  Part 1; the history of the California Sign State Route Spade Prior to the Sign State Route System, the US Route System and the Auto Trails were the only highways in California signed with reassurance markers.  The creation of the US Route System by the American Association of State Highway Officials during November 1926 brought a system of standardized reassurance shields to major highways in California.  Early efforts to create a Sign State Route ...

California State Route 70; the Feather River Highway

From 2017 through to early 2019 I drove the majority of the California State Route 70; the Feather River Highway from CA 89 southwest to CA 99. CA 70 is an approximately 178.5 mile state highway which starts at US 395 near the Nevada State Line and travels west through the Feather River Canyon to CA 99.  CA 70 is often referred to as the Feather River Highway" given it's close association with the river.  Historically CA 70 was previously signed as US 40A and CA 24.  The Legislative Routes prior to the 1964 California Highway Renumbering that made up the current route of CA 70 are as follows: -  Legislative Route Number 21 from US 395 westward to Oroville. -  LRN 87 from Oroville south to Marysville. -  LRN 232 from Marysville to the current junction with CA 99.  CA 70 was even dual signed with CA 99 into Sacramento on what was LRN 232 for a time. The change from US 40A/LRN 21/LRN 87/LRN 232 can be seen by comparing the 1963 State Highway Ma...
