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 US Route 60/70 through Hell (Chuckwall Valley Road and Ragsdale Road)

Back in 2016 I explored some of the derelict roadways of the Sonoran Desert of Riverside County which were part of US Route 60/70; Chuckwalla Valley Road and Ragsdale Road.


US 60 and US 70 were not part of the original run of US Routes in California.  According to USends.com US 60 was extended into California by 1932.  US 60 doesn't appear on the California State Highway Map until the 1934 edition.

Conversely US 70 was extended into California by 1934, it first appears on the 1936 State Highway Map.

When US 60 and US 70 were extended into California they both utilized what was Legislative Route Number 64 from the Arizona State Line west to Coachella Valley.  LRN 64 was part of the 1919 Third State Highway Bond Act routes.  The original definition of LRN 64 routed between Mecca in Blythe and wasn't extended to the Arizona State Line until 1931 according to CAhighways.org.

Interstate 375 in Detroit; a doomed freeway?

Recently while visiting the City of Detroit I drove the entirety of Interstate 375.


I-375 is a short 1.147 mile spur of I-75 in downtown Detroit which connects to the unsigned I-375 Business Spur on Jefferson Avenue.  I-375 is the southernmost segment of the Walter P. Chrysler Freeway which carried largely by I-75 in the City of Detroit.  Construction of I-375 began in 1959 and the freeway was open to traffic by late 1964 according to michiganhighways.org.

The average traffic count on I-375 ranges between approximately 14,000 vehicles at Jefferson Avenue and approximately 54,000 vehicles at I-75.  The low traffic counts on I-375 has recently led to proposals to put the freeway on a "road diet."  In 2013 the Michigan Department of Transportation announced that it may at some point in the future remove I-375.  In 2014 MDOT announced six proposals for I-375 which were eventually reduced to only two boulevard alternatives by 2017.  In late 2018 a six…

California State Route 173; former California State Route 2 and the last stand of the dirt State Highway

This past weekend I drove a portion of California State Route 173 east of CA 138 to the closure gate near Mojave River Forks Reservoir.   CA 173 is notable for being a former portion of CA 2 and having the last four miles of dirt State Highway still on the books in California.


CA 173 is a 25 mile State Highway which begins at CA 138 near Cajon Pass and ascends to CA 18 in the San Bernardino Mountains.  Presently CA 173 is the only State Highway that has a segment that has a dirt surface between Post Miles SBD 7.5 to SBD 11.5 near Mojave River Forks Reservoir.  Unfortunately said four mile segment of CA 173 has been closed to traffic since 2011.

Reportedly the route of CA 173 was originally built as an alternate haul road to Crest Drive through Waterman Canyon for the Lake Arrowhead Reservoir Project.  Lake Arrowhead Reservoir began construction in 1904 and wasn't completed until 1922.
