The final leg in Nebraska follows NE-71 south, then US-385 to Alliance. These are rural roads with occasional gravel sections. Check weather before departing, as snow can close passes.

Fuel Economics

• Fuel stops: Every 50-70 miles along I-90, but sparse on US-20 in Wyoming. Fill up in Sheridan, Douglas, and Lusk.

• Truck stops: Love's and Pilot locations in Sheridan and Douglas. Small stations in Lusk and Harrison.

Rest Stops

• Official rest areas: I-90 rest zones near Columbus, MT and Greybull, WY; I-25 near Kaycee, WY.
