A Closer Look At US 89 in Montana
U.S. Highway 89 in Montana stretches roughly 400 miles from the northern boundary of Yellowstone National Park at Gardiner to the Canadian border at the Port of Piegan, where the roadway continues into Alberta as Highway 2.
It is one of the state’s longest numbered routes and serves both local communities and travelers passing through Montana’s wide open spaces and scenic landscapes.
Along its path, US 89 intersects with several other major highways. In Livingston, it briefly overlaps with Interstate 90 and U.S. 191, providing connections west toward Bozeman and east toward Billings.
Farther north, US 89 joins U.S. 12 for a stretch through White Sulphur Springs, and this shared section links communities across central Montana. Near Great Falls, the highway overlaps with U.S. 87 and Montana Highway 200 and meets I‑15 at Vaughn before continuing northwest.
US 89 also intersects U.S. 2 in Browning and provides access to Glacier National Park via the Going‑to‑the‑Sun Road at St. Mary.
Because of these connections, US 89 links important regional corridors and helps tie Montana’s rural towns and natural attractions into the broader highway network.
