Wyoming Highway 225 begins its western end at exit 348 of
Interstate 80/
US 30 east of
Granite Canon. WYO 225 heads east toward Cheyenne, roughly paralleling I-80/US 30 to the south, as it was the former routing of the latter. Reaching the western outskirts of Cheyenne, the southern terminus of
Wyoming Highway 222 (Roundtop Road) is intersected, which heads north to
F.E. Warren AFB and also provides access to exit 357 of the interstate. Shortly thereafter, WYO 225 reaches its eastern end at exit 358 of I-80/US 30; however no access to the interstate is provided from westbound WYO 225. WYO 225 turns into
I-80 Business and
US 30 as US 30 leaves I-80 and joins the I-80 Business Loop west into Cheyenne, named West Lincolnway. ==History==
