U.S. Route 14 in Wyoming

U.S. Highway 14 (US 14) in the U.S. state of Wyoming runs east to west across the northern part of the state. The road connects South Dakota on the east with Yellowstone National Park on the west. It is mostly a two-lane surface road, except for several sections that it shares with Interstate 90 (I-90). The total length is about 400.3 miles (644.2 km).^[1]

While the official western terminus of the road is at the eastern gate of Yellowstone National Park, some commercially produced maps show US 14 within the park itself starting at a junction with US 89 and US 287 at West Thumb and following the northern shore of Yellowstone Lake. From the park, US 14 is cosigned with US 16 and US 20. The roads lead east out of the Absaroka Range and down the Shoshone River valley to Cody. Here, US 14A splits north toward Powell, while US 14/US 16/US 20 continues east across the Bighorn Basin to Greybull. At Greybull, US 16 and US 20 go south, while US 14 travels east to Shell, and the western slope of the Bighorn Mountains. The road ascends a windy path through steep Shell Canyon and rejoins US 14A at the top of the range at Burgess Junction.^[2] The road is designated as Bighorn Scenic Byway between Shell and Dayton on the eastern side of the mountain range. On the east side of the Bighorn Mountains, the road merges with I-90 and travels southeast to Sheridan. From Sheridan, the road continues east, rejoining with US 16 near Clearmont. The road travels across the Powder River Country to Gillette where it joins again with I-90 to Moorcroft. From here, it diverges north from I-90 briefly to junction with Wyoming Highway 24 (WYO 24) with access to Devils Tower National Monument. US 14 turns south and rejoins I-90 which it follows to the eastern border of Wyoming and South Dakota.

US 14 was originally planned to stop in Wall, South Dakota. In 1936, the road was extended to the Wyoming border, US 16 was rerouted through Newcastle, and the old US 16 was redesignated as US 14. Prior to 1940, US 14 followed the route currently serviced by US 14A through Lovell and Powell. In 1940, the highway took over WYO 520 between Burgess Junction and Greybull, and the old road was renamed WYO 14. Due to confusion, it was recommissioned as US 14A in 1965. In the 1960s, portions of the highway in the eastern part of the state became I-90.
