State Route 122 (SR-122) is a state highway in the U.S. state of Utah, connecting the ghost town of Hiawatha with SR-10.

Route description SR-122 begins at the east right-of-way line of the Utah Railway, opposite the coal mine and ghost town of Hiawatha in the Manti-La Sal National Forest. It heads east in generally straight lines, gradually descending a ridge from the foothills of Gentry Mountain into the Castle Valley. About two-thirds of the way to the end at SR-10, SR-122 meets a county road from Wattis, another former mining town.Google Maps street maps and USGS topographic maps, accessed July 2008 via ACME Mapper

History A pair of roads connecting the coal mining company town of Hiawatha with SR-10 was added to the state highway system in 1931, initially numbered SR-123 but changed to State Route 122 in 1933. One branch headed east along present SR-122; the other turned south at Hiawatha Junction (just east of the Utah Railway crossing) and passed east of Mohrland to end at SR-10 near Huntington. The latter branch was split off as State Route 236 in 1945 and removed from the state highway system in 1969.Utah Department of Transportation, Highway Resolutions :  , updated November 2007, accessed May 2008 Another branch, running southeast from Wattis to SR-122, became State Route 50 in 1935 and was also deleted in 1969.Utah Department of Transportation, Highway Resolutions :  , updated October 2007, accessed May 2008 A short truncation was made to SR-122 at its west end in 1993, after Hiawatha was disincorporated, so that the U.S. Fuel Company could gate the former Main Street. The end was moved from near a curve on Main Street north of Center Street to the east right-of-way line at the railroad crossing.Utah Department of Transportation, Highway Resolutions :  , updated November 2007, accessed May 2008
