Route description

Wyoming Highway 51 travels from the eastern outskirts of Gillette at an interchange with I-90/US 14/US 16 (Exit 128) and the eastern terminus of I-90 BUS east to the town of Moorcroft. Highway 51 travels east, passing through the communities of Wyodak and Rozet, south of the Campbell County fairgrounds [1], coal mines, and south of Wyodak power plant.[2] Wyoming 51 is the old alignment for US 14/US 16; and for most of its length closely parallels Interstate 90 which carries US 14/US 16. WYO 51 comes to an end at just under 25 miles at US 14/US 16/I-90 BUS.

WYO 51 is signed as a secondary state highway, but not marked from the Interstate 90 interchanges like most secondary state highway frontage roads.[1]


Wyoming Highway 51 is the original alignment of US Route 14 and US Route 16. With the construction of Interstate 90, US 14 and US 16 were realigned onto that highway.[1]
