State highways in Wyoming

In the U.S. state of Wyoming, Interstate 90 traverses the northeastern corner of the state, passing through the cities and communities of Sheridan, Buffalo, and Gillette.

Interstate 90 enters Wyoming from Montana and heads south concurrent with US 87 through hilly grasslands. It curves to the southeast and meets an interchange that serves the small community of Parkman. Continuing southeast, the highway intersects US 14 at a diamond interchange. US 14 joins I-90 and US 87 and the three routes curve east. After the freeway bends back to the southeast, it intersects the eastern end of WYO 345, then crosses the BNSF Railway (formerly the Chicago, Burlington and Quincy Railroad) and the Tongue River. The highway serves as the western terminus of WYO 339 and then passes over WYO 338 without an intersection just before it crosses Goose Creek. Just south of Goose Creek, US 14 and US 87 split off to the south of I-90 via a trumpet interchange. This road is also signed as a business loop of I-90 (BL 90).
