M-42 was replaced by M-37 in 1940, and US 131 was relocated around the same time north from Walton Junction along a new alignment to Fife Lake. From Fife Lake northward, US 131 replaced M-131. The portion of M-131 running west of Fife Lake became M-186 and the remaining piece of US 131 between M-113 and Walton Junction was added to M-113. The routing has remained unchanged since.
