Route 66 Wednesdays; Petrified Forest National Park

Back in 2012, I stopped in at Petrified Forest National Park on the Colorado Plateau which used to be crossed by US Route 66 in addition to Arizona State Route 63.


Petrified Forest National Park is mostly known for fossilized trees from the Late Triassic Period about 225 million years ago.  Petrified Forest National Park spans much of the border along the Navajo County and Apache County line between I-40 south to US 180.  Petrified Forest was set aside as a National Monument in 1906 to protect the fossils from theft and was elevated to a National Park in 1962.  Given that US Route 66 ran through Petrified Forest National Park, it has become associated with the highway. 

From I-40, access to the Painted Desert Visitor Center and the Park itself is fairly straightforward.


The northern annex of Petrified Forest contains several vistas of the Painted Desert.  The Painted Desert consists of a series of Badlands on the Colorado Plateau running from the east rim of the Grand Canyon easterly to Petrified Forest National Park.







US Route 66 before I-40 was built used to run across the south side of the modern traffic lanes and directly through the northern annex of Petrified Forest National Park.  US 66 would emerge east of the northern Petrified Forest Painted Desert Visitor Center onto Pinta Road.  The alignment of US 66 is plainly visible via satellite images.  The National Park Service even provided a historical marker where US 66 crossed the lanes occupied by I-40.




From the US 66 monument south to US 180 the routing of Park Road was once part of the original Arizona State Route 63.  AZ 63 apparently was created in 1932 and appeared on maps under state maintenance as late as 1951.  By 1956 maintenance of AZ 63 had been turned over to the National Park Service.

South of I-40 there is a series of petroglyphs that can be viewed via telescope to the west near the former Atlantic & Pacific Railroad siding of Adamana.




Formations like The Teepees, pictured below, are common in the Painted Desert.  The southern annex of Petrified Forest National Park has various formations with blue and purple color hues.



To the south of The Teepees, the park road traverses by Blue Mesa which can be accessed by the Blue Mesa Scenic Road.


Blue Mesa overlooks various clusters of fossilized trees.





South of Blue Mesa the Agate Bridge forms a small fossil bridge.  The Agate Bridge has been reinforced from the bottom with concrete.


South of the Agate Bridge the park road passes by the Crystal Forest.



Near the south gate of Petrified Forest is a large formation of fossilized logs known as the Rainbow Forest.  The Rainbow Forest seemed to have what was the largest cluster of fossilized trees along the park road.





The Park Road presently ends just short of US 180 as the National Park boundary ends.  The road continues as Petrified Forest Road about a quarter mile where it ends at US 180, AZ 63 would have never met the current designation.  Originally AZ 63 may have ended at the first alignment of US 70 but I'm uncertain as it moved to the present location in 1932.  AZ 63 ended at US 260 which was assigned over the previous US 70 alignment from 1932 until it was decommissioned in the 1950s.

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...
