Montana shares 14 Canadian border crossings with British Columbia, Alberta, and Saskatchewan provinces along its 545 mile, 877 kilometer northern border. The most heavily travelled ports are Sweetgrass, Roosville, and Piegan. These three are also major trucking portals between Canada and the U.S. Sweetgrass is by far the most heavily used port and carries almost as much traffic as all the other ports in Montana combined.
Important! Not all border crossings in Montana have the same regulations, hours of operations and rules. Make sure you confirm road conditions, border hours of operation, and any permit issues before you leave.
