The highway was proposed in the late 1990s to relieve truck congestion in Casper and Mills, particularly on WYO 220, and approved in 2002. The project used federal funding and began construction in 2013 after a series of eminent domain disputes delayed planning. WYO 257 opened to traffic on December 31, 2015.
