US Highway 2 — Montana

North Dakota Border to Havre to Shelby, MT (Hi-Line Corridor)

US Highway 2 across northern Montana — the Hi-Line — is one of the loneliest stretches of road in the lower 48 states. The highway runs parallel to the Canadian border and the BNSF Hi-Line rail corridor, crossing open high plains with almost no windbreak for hundreds of miles. Prairie blizzards that develop rapidly can produce whiteout conditions with near-zero visibility and drifting snow that buries the roadway. Services are sparse, temperatures can drop below -40°F, and the flat terrain offers no shelter from wind. For commercial drivers, the Hi-Line is a test of weather judgment and self-sufficiency.
