West-to-east planning list for overnight-capable truck stops on I-90 from Superior, Montana, through Missoula, Milltown, Butte, Three Forks, Belgrade, Columbus, Laurel, Billings and Hardin to Buffalo and Gillette, Wyoming, in exit order. Occupancy is unknown unless a listing says otherwise. This is not a live lot board. Lot List did not load a chain truck stop on I-90 east of Gillette to the South Dakota line, so that stretch is a gap on this page.

Montana allows overnight parking at its rest areas (12 hours, one space), which helps on the long gaps: Butte (Exit 122) to Three Forks (Exit 274) has no chain stop on this list, and Hardin (Exit 495) to Buffalo, Wyoming (Exit 58) is about 130 miles. Missoula, Butte, Laurel and Billings have the largest clusters.
