Mohave County Route 153 comprises an approximately 10-mile segment of Boundary Cone Road west of Oatman Highway (former US Route 66) to Arizona State Route 95. Boundary Cone Road is one of the oldest highway corridors in continuous use in Arizona as it was incorporated into General Beale's Wagon Road during 1857. Boundary Cone Road is named for a prominent rock formation in the Black Mountains which carries great significance to the tribes of Mohave Valley. Below what is now Boundary Cone Road can be seen branching east from Fort Mohave towards Sitgreaves Pass on the 1873 Bancroft's Map of California, Utah, Nevada and Arizona.
The modern alignment of Boundary Cone Road between Arizona State Route 95 and Oatman Highway appears on the 1970 United States Geological Survey Maps of Needles and the Boundary Cone. It isn't clear when Boundary Cone Road began being signed as Mohave County Route 153, but shields are present on Google Street View as early as 2011.
Part 2; a drive on Boundary Cone Road
Oatman Highway (former US Route 66 and Mohave County Route 10) passes through the ghost town of Old Trails. Oatman Highway intersects Boundary Cone Road within view of the namesake rock formation. Traffic heading to Bullhead City and Laughlin are directed to follow Boundary Cone Road.
As westbound Boundary Cone Road begins to descend towards Arizona State Route 95 and the Fort Mohave Reservation a Mohave County Route 153 shield can be seen.
