State Route 37 (SR-37) is a state highway in the U.S. state of Utah, forming a 270° loop through the western part of the Ogden-Clearfield metropolitan area. The route is 12.35 miles (19.88 km).When the road was added to the state highway system in 1915 and numbered in 1927, it formed a connection from Ogden to Hooper. However, after a series of changes, SR-37 does not enter Ogden and extends further south to Sunset.
