Old US Route 89 (Arizona State Route 89) between Prescott and Wickenburg

Back in the early 2000s I frequently drove a decommissioned part of US Route 89 between Prescott in Yavapai County and Wickenburg in Maricopa County.


US Route 89 was one of the original US Routes in Arizona and was plotted out from the beginning of the US Route system.  US 89 in it's original form ran from Nogalas, AZ at the Mexican border to Spanish Fork, UT.  In the planning stages of the US Route System the route of US 89 was not planned to extend south of Flagstaff.  US 89 was likely to be extended via what became the first AZ 79 via Jerome since it appears to have been first numbered AZ 89.  US 280 was planned to run between Phoenix and Flagstaff which can be seen on this 1927 Arizona State Highway Map.  It isn't fully clear if US 280 was ever actually field signed.

In 1992 US 89 was truncated from the Mexican border to Flagstaff at US 180.  This truncation led to the creation of the 104.5 mile AZ 89 running on the former US 89 mainline between Ash Fork and Wickenburg in addition to AZ 89A which was plotted between Flagstaff to Prescott.  USends.com details the history of the endpoints of US Route 89.

From AZ 69 in downtown Prescott the route of AZ 89 exits the City south on Montezuma Street and White Spar Road.  Upon leaving the City of Prescott AZ 89 enters Prescott National Forest.


The route of AZ 89 traverses through the Bradshaw mountains southward through Prescott National Forest for 20 miles before emerging in Wilholt.   AZ 89 is surprisingly curvy for a former US Route and follows the cliff-face mostly between Prescott and Wilholt.







From Wilholt the route of AZ 89 traverses 8 miles southward to Kirkland Junction where the highway meets Yavapai County Route 15.  Yavapai County Route 15 acts as a County Level continuation of AZ 96 which is off to the west near Bagdad.

South of Kirkland Junction the route of AZ 89 enters Yarnell 13 miles to the south.  The following 9 miles of AZ 89 over Yarnell Hill to AZ 71 in Congress is the most notable part of the highway due to the duel one-way configurations.  The southbound grade of AZ 89 is the higher of the two and original alignment of US 89.  The northbound grade was added at some point during the late 1960s/1970s.  Two lanes on the southbound grade off of Yarnell Hill must have been a scary sight to behold during the heyday of US 89.

There is an overlook of both grades in AZ 89 descending Yarnell Hill.  The views extend southward into the Sonoran Desert towards Congress and Wickenburg. 








Yarnell unfortunately mostly known these days for the June 2013 Yarnell Hill Fire which killed 19 firefighters and razed about half the community.  Despite the small 8,400 acre size the Yarnell Hill Fire was the deadliest in Arizona State History.

From Congress the route of AZ 89 extends almost 10 miles south to US 93 on the northern outskirts of Wickenburg.  Before US 89 was truncated the route of US 93 terminated at US 89 north of Wickenburg.

Yes, the color of your nearby fire hydrant matters...

...and here's why. You will find White, Red, Yellow and Violet colored fire hydrants pretty much everywhere.  But there's a reason for this - and it's because of the National Fire Protection Association (NFPA).  This association has issued guidelines for color coding standards for fire hydrants.  These color codes from the body of the hydrant, top of the hydrant, and in some municipalities the outlet caps are designed to allow fire fighters to know what type of system, water flow rate (Gallons Per Minute or GPM), and level of water pressure.  This guideline is known as NFPA 291 and is intended to be used universally throughout the United States. The NFPA guidelines are specific to the body and the top cap of the hydrant.  If a hydrant is WHITE or YELLOW - it means that it is connected to a public/municipal water system.  If a hydrant is RED - the hydrant is connected to a private system, typically a well.  These are most common in rural or unincorporated areas

Legend of the Ridge Route; a history of crossing the mountains between the Los Angeles Basin and San Joaquin Valley from wagon trails to Interstates

Over the past two decades I've crossed the Interstate 5 corridor from Los Angeles north over the Sierra Pelona Mountains and Tehachapi Range to San Joaquin Valley what seems to be an immeasurable number of times.  While Interstate 5 from Castaic Junction to Grapevine via Tejon Pass today is known to most as "The Grapevine" it occupies a corridor which has been traversed by numerous historic highways.  The most notable of these highways is known as the "Ridge Route."  This article is dedicated to the Ridge Route and the various highways that preceded it.  This blog is part of the larger Gribblenation US Route 99 Page.  For more information pertaining to the other various segments of US Route 99 and it's three-digit child routes check out the link the below.

Establishing the numbering conventions of California's chargeable Interstates

The Federal Highway Aid Act of 1956 brought the Interstate Highway System into existence which would largely be constructed by Federal Highway Administration fund matching.  The Interstate Highway System was deliberately numbered to run opposite the established conventions of the US Route System.  While the Interstate Highway numbering conventions are now well established there was a period during the late 1950s where they were still being finalized.  This blog examines the history of the establishing of the chargeable Interstate Highway route numbers in California.  The above blog cover depicts the Interstate Highway route numbers requested by the Division of Highways in the Los Angeles area during November 1957.  The establishment of the numbering conventions of California's chargeable Interstates The Interstate Highway System was not created in a vacuum by way of the passage of the 1956 Federal Highway Aid Act.  The beginning of the Interstate Highway System can be found in the
