Route description
MT 17 begins along the Canada–United States border at the Chief Mountain Border Station and Quarters. On the Canadian side of the border, the road continues as Alberta Highway 6. The first 3+1/3 mi of the route lie within Glacier National Park. As the road winds through the coniferous forest, Chief Mountain dominates the landscape. The road continues southeast outside of the park boundary for nearly 11 mi. Scenic viewpoints provide people traveling the road an opportunity to photograph the mountains. The road ends at US 89 a few miles north of Babb.

The road is classified by the Montana Department of Transportation (MDT) as an "off-system route", meaning that while it is a numbered highway within the state highway system, it is not designated as a primary or secondary road for funding eligibility. As such, MT 17 is not maintained by MDT.
