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. 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. ==History==
