Utah State Route 137

SR-137 looking towards Wasatch Plateau Near Gunnison

State Route 137 is configured as a loop of US-89,[3] with a short southern spur to service the center of Mayfield.[1] It begins in Gunnison as 600 S at its intersection with Main Street (US-89), and travels eastward, turning southeast towards Mayfield as it passes the end of a mountain range.[3] At about the 7-mile (11 km) mark, as the route enters Mayfield's town limits, the southern spur splits off and travels south along Main Street for about 0.5 miles (0.80 km).[1] The main leg of the route turns north on State Street and continues the 3.7 miles (6.0 km) north to its terminus at US-89.[3]

State Route 137 was established in 1933 as the road "from Route 89 southerly to Mayfield thence westerly to route 89 at Gunnison".[2] The route has remained essentially unchanged since then, as its current description reads "From Route 89 in Gunnison easterly to Mayfield; then northerly to Route 89".[1]

The entire route is in Sanpete County.
