The route is approximately 27 miles (43 km) long and is the only road with access to Sundance Ski Resort and the Aspen Grove Family Camp and Conference Center sponsored by the Brigham Young University Alumni Association.

The route runs east from Highland and up American Fork Canyon, where it enters the Uinta National Forest. Shortly after, it passes Timpanogos Cave National Monument, a famous group of caves buried in the side of the canyon. The route continues up the canyon and bends to the south where it passes the east side of Mount Timpanogos. After passing Sundance Ski Resort, the road links up with US-189 in Provo Canyon.^[3]

History

UT 92 Scenic Biway marker

The state legislature created State Route 80 in 1935, connecting SR-1 (US-91, now I-15/US-89) near Point of the Mountain with SR-74 south of Alpine.^[4] An extension in 1941 took SR-92 east to the Uinta National Forest boundary in American Fork Canyon, replacing a short piece of SR-146 (created in 1933^[5]) from SR-74 to the mouth of the canyon.^[6] At the other end of the highway, State Route 168 was built in 1933 as a forest road^[7] and numbered in 1935, connecting SR-7 (US-189) with Aspen Grove.^[8] SR-80 was extended through the forest to SR-7, absorbing SR-168, in 1953. Because the number 80 was needed for I-80, SR-80 was renumbered SR-92 in the 1977 renumbering.^[9]
