A large portion of WV 37 was relocated in eastern Wayne County about 1970 as a result of the construction of East Lynn Lake, which flooded the route's former path along East Fork Twelvepole Creek. The highway was relocated up a series of side valleys from just downstream of the dam to near Kiahsville.[2] East of Kiahsville, the road was moved to a higher elevation out of the lake's floodplain.[3]
