U.S. Route 20 (US 20) is a west-east highway that travels from Targhee Pass at the Idaho state line to the west portion of Yellowstone National Park at the Wyoming state line.
Route description[]
US 20 enters Montana from Idaho at Targhee Pass at the Continental Divide. From there, it curves north and east down the mountain along a tree-lined, two-lane highway with a westbound climbing lane. An access road to the north provides access to Hebgen Lake. The highway then continues through Yellowstone National Park to Wyoming.
