2016 Fall Mountain Trip Part 20; US Route 160 in Arizona

Following reaching the western terminus of US Route 163 in Kayenta I turned west on US Route 160 towards US 89 and the Grand Canyon.


This blog serves as Part 20 of the 2016 Fall Mountain Trip Series, Part 19 can be found here:

2016 Fall Mountain Trip Part 19; US Route 163 through Monument Valley 

US 160 through Arizona is entirely contained within the Navajo Nation from the New Mexico State line westward to US 89 near Tuba City.  The current designation of US 160 was extended into Arizona in 1970.

The original designations on the current corridor of US 160 in Arizona was AZ 364 from the New Mexico State Line west to Teec Nos Pos and AZ 64 all the way to US 89.  The designation of AZ 64 was extended east of Cameron in 1961 to the New Mexico State Line via the current corridor of US 160 and US 64.  AZ 64 can be seen built all the way east to the Navajo County line on this 1961 Arizona Highway sectional map.

In 1966 the current route of US 160 from the New Mexico State Line to US 89 was changed to US 164.  US 164 from Arizona extended eastward to a terminus at Cortez, Colorado.  Within Arizona the route of US 164 apparently multiplexed US 89 all the way to Flagstaff.   Some of the US 164 field signage can be seen on USends.com.

In 1970 US 160 was rerouted from Crescent Junction, Utah onto it's current route in Arizona.  The change to US 160 can be seen on this 1971 Arizona Highway sectional map.

As shown in the blog cover photo I made a right hand turn from US 163 onto US 160 westbound in Kayenta of Navajo County. West of Tsegi US 160 meets a significant junction with AZ 564 which is an artifact of AZ  64.


AZ 564 provides access to Navajo National Monument and was covered on a previous blog.

Arizona State Route 564 and Navajo National Monument

Near the Coconino County Line US 160 west intersects AZ 98.


In Tuba City US 160 west intersects AZ 264.  AZ 264 is the longest child route of AZ 64 and extends east through the Hopi Nation and Navajo Nation to NM 264.


West of Tuba City US 160 terminates at US 89.  I turned southward on US 89 to reach AZ 64 to access Grand Canyon National Park.

Old California State Route 140 and California State Route 120 entrances to Yosemite National Park

This past October I sought out the original Yosemite National Park entrance alignments of California State Route 140 and California State Route 120.


Presently CA 120 enters Yosemite National Park in Tuolumne County via the modern Big Oak Flat Road.  Originally CA 120 entered Yosemite National Park via the Old Tioga Pass Road and CA 140 a entered via the Old Big Oak Flat Road.  Previously the history of the Big Oak Flat Road and Tioga Pass Road were discussed on Gribblenation.  Articles pertaining to the Big Oak Flat Road and Tioga Pass Road within the boundary of Yosemite National Park can be found below.

US Route 101 from Cannon Beach, Oregon over the Columbia River via the Astoria-Megler Bridge

This past September I drove a segment of US Route 101 from Cannon Beach, Oregon northward over the Columbia River into Washington State via the Astoria-Megler Bridge.


US 101 from Cannon Beach, Oregon northward to Megler, Washington is a shade under 30 miles.  Despite the short length this particular segment of US 101 has several notable locales in; Cannon Beach, Seaside, Astoria and the Astoria-Megler Bridge.


My trip on US 101 began in downtown Cannon Beach after taking US 26 on the Sunset Highway west out of Portland.


Cannon Beach is an incorporated City within Clatsop County with an approximate population of around 1,700.   Cannon Beach is located on the Pacific Ocean off of Ecola Creek.  Ecola Creek and what is now Cannon Beach was explored by William Clark of the Lewis & Clark Expedition in 1805.  During the ensuing decades a small community known as Elk Creek was settled near Ecola Creek.   In 1846 a cannon from the wrecked USS Shark landed south of Elk Creek near Arch Cape. …

Box Canyon Road (former US 60, US 70 and the second California State Route 195)

This past month while visiting Riverside County I drove Box Canyon Road from Interstate 10 near Chiriaco Summit southwest to Mecca in Coachella Valley.  Box Canyon Road is mostly known for being the original alignment of US 60/70 when they were expanded into California.


Box Canyon Road is an approximately 15.8 mile road between I-10/Cottonwood Springs Road near Chiriaco Summit which travels southwest through the Mecca Hills to Coachella Valley where it becomes 66th Avenue. 


Box Canyon Road follows a naturally cut wash through the terrain of the Mecca Hills.  The path of Box Canyon Road has been a known route of travel from Coachella Valley to the Colorado River and eastern Sonoran Desert for centuries.  During the California Gold Rush a wagon route known as the Bradshaw Trail was plotted through the Sonoran Desert by William D. Bradshaw.  The Bradshaw Trail was plotted in 1862 through the Sonoran Desert east over the Colorado River to a new mining strike found in La Paz, Arizona.  B…
