The Sweetgrass–Coutts Border Crossing connects the town of Sweet Grass, Montana, with the village of Coutts, Alberta, on the Canada–United States border. I-15 on the American side joins Alberta Highway 4 on the Canadian side. Similarly, BNSF Railway and Canadian Pacific Railway (CP) connect. A primary conduit for cross border trade estimated at CA$6 billion, it is the busiest crossing for both the province of Alberta and state of Montana, and among the busiest west of the Great Lakes.
