History[]

Wyoming Highway 75 was created during the early 1970s with the inception of the Wyoming secondary state route system. Highway 75 was routed along the path of present day Wyoming Highway 487 between the two junctions of current Wyoming Highway 77 in Shirley Basin. When Wyoming 487 was rerouted over Highway 75, old WYO 487 was recommissioned as WYO 77, and WYO 75 was decommissioned. The renumbering occurred in the mid-1970s.^[2]
