'''State Route 66''' ('''SR&nbsp;66''') is a surface road in the U.S. state of [[Arizona]] in [[Mohave County|Mohave]], [[Coconino County, Arizona|Coconino]], and [[Yavapai County, Arizona|Yavapai]] Counties. In 1914, the road was designated as part of the [[National Old Trails Highway]] but in 1926 was re-designated as U.S. Route 66 (US&nbsp;66).<ref>{{cite web |url = http://willowcreekriparianpreserve.org/website_willowcreek_008.htm |title = National Old Trails Highway |archive-url = https://web.archive.org/web/20131207123649/http://willowcreekriparianpreserve.org/website_willowcreek_008.htm |archive-date=December 7, 2013 |access-date = February 11, 2012 }}</ref> In 1985, US&nbsp;66 was dropped from the highway system. Parts of the highway were either absorbed into [[Interstate 40 in Arizona|Interstate&nbsp;40]] (I-40), turned over to the state (SR&nbsp;66), or turned over to [[Yavapai County, Arizona|Yavapai County]].

==Route description==
SR&nbsp;66 is a relic of the former [[U.S. Route 66 in Arizona|US&nbsp;66]] and is the only part of old US&nbsp;66 in Arizona to have state route markers. In 1990, the state turned over the easternmost {{convert|16.8|mi|km|1}} of SR&nbsp;66 (known as Crookton Road) to Yavapai County for maintenance.<ref name="Arizona Department of Transportation">{{cite web |author = Arizona Department of Transportation |author-link = Arizona Department of Transportation |url = http://www.azhighwaydata.com/resolutions/?resnum=1990-07-A-053 |title = ADOT Right-of-Way Resolution 1990-07-A-053 |accessdate = May 5, 2008 }}</ref>
===Mohave County===
SR&nbsp;66 begins at the [[Intersection (road)|intersection]] of Andy Devine Street and Michael Street where the roadway continues westward as [[U.S. Route 66 in Arizona#Historic Route 66|Historic US&nbsp;66]]. {{convert|1230|ft|m|0}} northeast of the Andy Devine and Michael Street intersection, it meets [[Interstate 40 in Arizona|I-40]]/[[U.S. Route 93 in Arizona|US&nbsp;93]]. {{convert|0.45|mi|km|3}} northeast of I-40/US&nbsp;93, it then becomes a [[divided highway]] for {{convert|4.63|mi|km|2}} before turning into a two-lane [[undivided highway]]. {{convert|12|mi|km}} down the road, it passes through the [[census-designated place|CDP]] of [[Antares, Arizona|Antares]] while curving to the east-southeast. After Antares, it passes through [[Hackberry, Arizona|Hackberry]] where it meets [[County Route 141 (Mohave County, Arizona)|CR&nbsp;141]] (Hackberry Road). It then passes through the [[census-designated place]]s of [[Crozier, Arizona|Crozier]], [[Truxton, Arizona|Truxton]], and [[Peach Springs, Arizona|Peach Springs]] before entering [[Coconino County, Arizona|Coconino County]].

===Coconino and Yavapai counties===
East of the [[Mohave County, Arizona|Mohave]]&ndash;[[Coconino County, Arizona|Coconino]] county line, SR&nbsp;66 has an [[Intersection (road)|intersection]] with Indian Route&nbsp;18 in the [[Hualapai Indian Reservation]]. SR&nbsp;66 then become a four-lane [[divided highway]] at the [[Grand Canyon Caverns]]. After the Grand Canyon Caverns, SR&nbsp;66 then becomes an [[undivided highway]] and curves to the southeast and Coconino&ndash;[[Yavapai County, Arizona|Yavapai]] county line twice before having an intersection with [[Pica Road]]. After Pica Road, it crosses the Coconino&ndash;Yavapai again where the maintenance of SR&nbsp;66 by the [[Arizona Department of Transportation]] ends.

After the eastern terminus of the [[Arizona Department of Transportation|ADOT]]-maintenance section of SR&nbsp;66 near the intersection of [[Pica Canyon Road]], it makes two curves before entering [[Seligman, Arizona|Seligman]]. West of [[Seligman, Arizona#Seligman Commercial Historic District|downtown Seligman]] and south of [[Seligman Airport]], SR&nbsp;66 began its [[Concurrency (road)|concurrency]] with [[Business routes of Interstate 40#Seligman|Interstate&nbsp;40 Business]]. BL&nbsp;40/SR&nbsp;66/Historic US&nbsp;66 passed by many attractive sites in downtown Seligman including the [[Delgadillo's Snow Cap Drive-In|Snow Cap Drive-In]].

==History==

===U.S. Route 66===
{{main|U.S. Route 66 in Arizona#History|l1=U.S. Route 66 in Arizona}}
Between the [[California]] state line and Kingman, the original alignment is now known as [[County Route 10 (Mohave County, Arizona)|Oatman Highway]] and passed through the old mining town of [[Oatman, Arizona|Oatman]]. A later alignment (via [[Yucca, Arizona|Yucca]]) is now Interstate 40. The older alignment passes through the [[Black Mountains (Arizona)|Black Mountains]] complete with numerous hairpin turns. This area is desert.

From Kingman to Seligman, it took a path now followed by modern State Route 66.

East of Seligman and continuing beyond [[Flagstaff, Arizona|Flagstaff]], the area is mountainous (not desert) and covered with [[pine]] forests. Continuing toward the [[New Mexico]] state line, much of US 66 has been replaced with I-40. Various stretches of the old highway exist as [[frontage road]]s and [[business loop]]s of I-40.

===State Route 66===
In 1984, US 66 was officially removed from the state highway system of Arizona.  Most of the old highway had been replaced by I-40, but the portion of the interstate between Kingman and Seligman was developed to follow a new alignment to the south. The remaining northern segment ultimately became SR 66.<ref>{{cite web |author = Arizona Department of Transportation |author-link = Arizona Department of Transportation |url = http://www.azhighwaydata.com/resolutions/pdf/resolutionfull/1984-10-A-065.pdf |title = ADOT Right-of-Way Resolution 1984-10-A-065 |accessdate = May 5, 2008 }}</ref>  In 1990, the state turned over the easternmost {{convert|16.8|mi|km|1}} of SR 66 (known as Crookton Road) to Yavapai County for maintenance.<ref name="Arizona Department of Transportation"/>
