Utah State Route 101
State Route 101 (SR-101) is a long state highway located in the U.S. state of Utah. The route serves as a spur route into the Uinta-Wasatch-Cache National Forest through the cities of Wellsville and Hyrum, with an intermediate intersection with U.S. Route 89 (US-89) and US-91. SR-101 starts at an intersection of Main Street and SR-23 (Center Street) in Wellsville. Heading generally eastward, the highway terminates at the Hardware Ranch Wildlife Management Area. SR-101 was first designated in 1931 as a loop off SR-1 from Logan, south to Hyrum, and west to Wellsville.
