State Route 37 (SR-37) is a short spur route in Dale County in the southeastern part of Alabama. Only one mile long, the southern terminus of the route is at a junction with U.S. Highway 84 and State Route 134 at Daleville and leads to the Tank Hill Gate at Fort Rucker, where the route ends. SR-37 is routed along a two lane undivided highway for its brief existence.
SR-37 begins at an intersection with US-84/SR-12/SR-134 in Daleville, heading north on two-lane undivided Tank Hill Road through woodland. The route crosses CR 114 (Joe Bruer Road) before turning northeast through more woods and ending at the Tank Hill Gate to Fort Rucker.
The current SR-37 is the second incarnation of the route. In 1940, the original route was designated, leading from near Marvyn to near Oxford. In 1954, the section of the route from Opelika northwards was redesignated as U.S. Highway 431. In 1960, SR-37 was extended southward, from Marvyn to Hurtsboro. That route was replaced in 1995 when State Route 51 was extended northward from Hurtsboro to what was then the northern terminus of SR-37 at its junction with Interstate 85. The present SR-37 was designated along its current route in 1995.
