History
South Dakota 37 was in place by 1926, and largely has used the same alignment since. The only significant exception was in northeast South Dakota, where SD 37 originally went westward from Groton to Bath, then north via Columbia to Houghton, where it continued to Hecla. This segment was rerouted to the current alignment by 1929.
