Proceeding west to east for 123 miles (nearly 200&nbsp;km), the highway starts south of [[Panguitch, Utah|Panguitch]] at an intersection with [[U.S. Route 89 in Utah|US-89]], crosses part of [[Dixie National Forest]] and [[Bryce Canyon National Park]], continues through the small towns of [[Tropic, Utah|Tropic]], [[Cannonville, Utah|Cannonville]], and [[Henrieville, Utah|Henrieville]]. It crosses various parts of [[Grand Staircase–Escalante National Monument]] (GS-ENM), continues northeast through [[Escalante, Utah|Escalante]] and over the [[Escalante River]], then over "The Hogback",<ref>{{cite book |last=Long |first=Denise |title=PULL OVER!

It then proceeds north through more of GS-ENM, [[Boulder, Utah|Boulder]], the [[Aquarius Plateau]], and [[Grover, Utah|Grover]], ending in [[Torrey, Utah|Torrey]] at an intersection with [[Utah State Route 24|SR-24]], five miles (8&nbsp;km) west of [[Capitol Reef National Park]]. The {{convert|30|mi|km|adj=on}} long portion of the highway that ascends and descends [[Boulder Mountain (Utah)|Boulder Mountain]] on the Aquarius Plateau is known as Boulder Mountain Highway.

==History==
[[Image:RedRockUtah.jpg|right|thumb|Red Canyon, Dixie National Forest]]
The road from [[Bryce Canyon Junction, Utah|Bryce Canyon Junction]] to [[Tropic, Utah|Tropic]] was added to the state highway system in 1914, and in 1923 a branch from [[Tropic Junction, Utah|Tropic Junction]] to [[Bryce Canyon]] was built as a [[forest road]].<ref name=resolutions-12>{{UDOT Resolutions |routenum=12 }}&nbsp;{{small|(9.72&nbsp;MB)}}, updated September 2007, accessed May 2008</ref> The [[State Road Commission (Utah)|State Road Commission]] numbered the route to Bryce Canyon SR-12 in the 1920s,<ref>[[State Road Commission (Utah)|State Road Commission]], [http://www.nps.gov/archive/pisp/adhi/fig23a.jpg Utah State Trunk Lines], 1923</ref> and in 1927 the state legislature assigned it to both branches, to Bryce Canyon and Tropic,<ref>{{cite UTSR|year=1927|quote=12. From Hillsdale, about 7 miles south of Panguitch, southeasterly via Tropic Junction; to Bryce Canyon; also from Tropic Junction to Tropic.}}</ref> but split off the branch to Tropic as '''State Route 54''' in 1931. That same year, a new '''State Route 120''' was created, continuing the road from Tropic to [[Henrieville, UT|Henrieville]],<ref>{{cite UTSR|year=1931|quote=(54) From Tropic junction on route 12 to Tropic." "(120) From Tropic southerly via Cannonville to Henrieville.}}</ref> and in 1935 it became part of SR-54.<ref>{{cite UTSR|year=1935}}</ref> Another road was also added to the state highway system in 1914, connecting [[SR-22 (UT)|SR-22]] at [[Widtsoe, Utah|Widtsoe]] with [[Escalante, UT|Escalante]],<ref name=history>[[Utah Department of Transportation]], [http://www.udot.utah.gov/download.php/tid=1348/StateRouteHistory.pdf State Route History] {{Webarchive|url=https://web.archive.org/web/20070225155542/http://www.udot.utah.gov/download.php/tid=1348/StateRouteHistory.pdf |date=2007-02-25 }}. Retrieved July 2007.</ref> and it was numbered '''State Route 23''' in 1927.<ref>{{cite UTSR|year=1927|quote=23. From Widtsoe easterly to Escalante.}}</ref> An extension took SR-23 northeast to [[Boulder, UT|Boulder]] in 1941,<ref>{{cite UTSR|year=1941|chapter=34}}</ref> and in 1947 SR-54 absorbed SR-23, with the Widtsoe-Escalante road dropped in favor of Henrieville-Escalante.<ref>{{cite UTSR|year=1947|chapter=49|quote=Route 54.

This spur became a new [[SR-63 (UT)|SR-63]] in 1975, and in 1985 the route was extended back north from Boulder to SR-24, using a different route than the old SR-117 north of Grover.<ref name=resolutions-12/>
