Park City to Gillette: Wyoming's Wild West Road Trip

The 480-mile journey from Park City, UT to Gillette, WY follows I-80 east and then I-25 north, crossing the Continental Divide twice. This route bypasses the historic Lincoln Highway—America's first transcontinental road—which now runs parallel as US-30. Ranchers still move cattle across these highways, so expect delays near Evanston and Rawlins. For tips on how to find the best stops and hidden gems between cities, read our dedicated guide.

I-80 between Laramie and Rawlins is notorious for high winds—sustained gusts over 50 mph. Many stretches have signs warning of crosswinds. RVs and high-profile vehicles should slow down. Cell service is spotty west of Rawlins.

• Rest areas: Every 30-40 miles on I-80; most have restrooms and picnic tables. Notable: Bitter Creek Rest Area (mile 185) with scenic overlook.
• Fatigue management: Stop every 2 hours. Recommended stops: Evanston (mile 40), Rawlins (mile 135), Cheyenne (mile 280).
