U.S. Route 89A is a 91.74-mile (147.64 km) north–south auxiliaryU.S. highway (though its actual direction of travel is more east–west) in southwesternKane County,Utah and northeasternCoconino County,Arizona in the southwestern United States. The highway is an old routing ofU.S. Route 89 fromBitter Springs, Arizona toKanab, Utah. The state of Arizona has designated this highway the Fredonia-Vermilion Cliffs Scenic Road.[3] The highway is used to access the North Rim ofGrand Canyon National Park and is known for theNavajo Bridge. Until 2008, the Utah portion was signedState Route 11. The route provides the only direct road connection between theArizona Strip and the rest of Arizona.
The highway's southern terminus is atU.S. Route 89 south ofPage, Arizona. Its northern terminus is inKanab, Utah, also atUS 89. US 89A runs near or throughLee's Ferry, theNavajo Bridge,Vermilion Cliffs, theKaibab Plateau, andFredonia, Arizona. The eastern portion of the highway runs through part of theNavajo Nation. FromJacob Lake,Arizona State Route 67 (AZ 67) branches off south, leading to the North Rim ofGrand Canyon National Park. US 89A then continues north to the neighboring cities ofFredonia, Arizona andKanab, Utah. The Utah portion of US 89A is defined by Utah Code Annotated §72-4-114.[4]
This was part of mainline US 89 until the construction ofGlen Canyon Dam. In 1960, US 89 was moved to a new, more northerly route and the old route became US 89A.
The Utah segment of US 89A was first commissioned as part of Utah State Route 11. This highway ran fromNephi to theArizona state line near Kanab. This route is still drivable as the modern US 89A, US 89, andUtah SR-132. With the establishment of theUnited States highway system in 1926, most of SR-11 was used for the routing of US 89 through southern Utah; the internal designation used by state agencies remained SR-11.[5] In 1969, as part of aseries of changes to state routes, the portion north of Sevier Junction (I-70 and US 89 nearJoseph) was transferred to other routes, removing the only part of State Route 11 that was signed with the state designation. It is also during this time that a new alignment for US 89 was constructed to serve theGlen Canyon Dam, with SR-11 being now signed as US 89A south of Kanab and US 89 to the north. As part of the1977 Utah state route renumbering to conform signage and legislative definitions, SR-11 was truncated to what is now signed US 89A.[5] The route was signed SR-11, with "TO US 89A" at the northern terminus in Kanab and a "TO US 89" at the Arizona state line. In 2008, however, SR-11 was deleted after a bill in the Utah legislature was passed to restore U.S. Route 89A in Utah.[6]
From 1941 to 1992, there was a discontinuous southern portion US 89A running fromFlagstaff toPrescott, Arizona, now designatedArizona State Route 89A.
