State Route 12 or Scenic Byway 12 (SR-12), also known as "Highway 12 — A Journey Through Time Scenic Byway", is a 122.863-mile-long (197.729 km) state highway designated an All-American Road located in Garfield County and Wayne County, Utah, United States.

Route description

SR-12, as seen from the Head of the Rocks overlook

Proceeding west to east for 122 miles (nearly 200 km), the highway starts south of Panguitch at an intersection with US-89, crosses part of Dixie National Forest and Bryce Canyon National Park, continues through the small towns of Tropic, Cannonville, and Henrieville. It crosses various parts of Grand Staircase-Escalante National Monument (GS-ENM), continues northeast through Escalante and over the Escalante River, then over the Hogback,[2] a narrow ridge with no guardrails or shoulders and steep drop-offs on each side. It then proceeds north through more of GS-ENM, Boulder, the Aquarius Plateau, Grover, ending in Torrey at an intersection with SR-24, five miles (8 km) west of Capitol Reef National Park. The 30-mile (48 km) long portion of the highway that ascends and descends Boulder Mountain on the Aquarius Plateau is known as Boulder Mountain Highway.

The segment of SR-12 between the US-89 and SR-63 junctions is part of the National Highway System.[3]

Traffic volume

The Average Daily Traffic (AADT) on SR-12 is at its greatest at its western junction with US-89, where the count for 2005 was 2,430. At its other end, at the junction with SR-24, the traffic bottoms out at 435.[4]

History

Red Canyon, Dixie National Forest

The road from Bryce Canyon Junction to Tropic was added to the state highway system in 1914, and in 1923 a branch from Tropic Junction to Bryce Canyon was built as a forest road.[5] The State Road Commission numbered the route to Bryce Canyon SR-12 in the 1920s,[6] and in 1927 the state legislature assigned it to both branches, to Bryce Canyon and Tropic,[7] 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,[8] and in 1935 it became part of SR-54.[9] Another road was also added to the state highway system in 1914, connecting SR-22 at Widtsoe with Escalante,[10] and it was numbered State Route 23 in 1927.[11] An extension took SR-23 northeast to Boulder in 1941,[12] and in 1947 SR-54 absorbed SR-23, with the Widtsoe-Escalante road dropped in favor of Henrieville-Escalante.[13] State Route 117, running southeast from SR-24 near Teasdale to Grover, became a state highway in 1931,[14] and was extended south to Boulder in 1957, becoming part of SR-54 in 1966.[15] In 1969, SR-54 became part of SR-12, but most of former SR-117 was dropped, leaving SR-12 to stretch from Bryce Canyon Junction to the north limit of Boulder (at the Dixie National Forest boundary), with a short spur to Bryce Canyon. This spur became a new SR-63 in 1975, and in 1985 the route was extended back north from Boulder to SR-24, using a different route than old SR-117 north of Grover.[5]
