Missouri Route 37

Route 37 begins at US 160 in Golden City as a short concurrency with Route 126. After a few blocks, Route 37 turns south. At Avilla, the highway intersects Route 96 and joins this highway (going west) for one mile (1.6 km) before turning south again. Near Sarcoxie is an intersection with Interstate 44. It will be united with Business I-44 to the east side of Sarcoxie, the two of them following an old alignment of U.S. Route 166. The highway turns southeast towards Pierce City where there is a brief wrong-way concurrency with Route 97.

At Monett, Route 37 intersects U.S. Route 60 and becomes part of the Trail of Tears Automobile Route all the way to the state line. At Cassville, Route 37 produces one of two official business routes and on the south side of the town it intersects Route 76/Route 86 and the northern terminus of Route 112. At Washburn is the eastern terminus of Route 90 and at Seligman is the southern terminus of Route 112. Three miles south of Seligman, Route 37 crosses the Arkansas state line where it becomes Arkansas Highway 37. About one half of a mile south of the state line, Arkansas 37 ends at U.S. Route 62.
