Unrestricted traffic flow

No disturbance of wild and scenic river

Abundant wildlife not distressed

U.S. Highway 2 is built on a very steep slope above the wild and scenic Flathead River at the south end of Glacier National Park. Cracks opened across the two-lane highway at a section built over 14 feet of deep fill held up by a reinforced earth wall. Initially the state officials thought the wall was failing. Landslide Technology installed instruments and detected a deep landslide extending down to the river.

A high traffic area for both vehicles and wildlife, the method of fixing the road had to allow traffic to flow and wild goats to cross the landslide to lick salts on the side of the river. In association with a structural engineer from Seattle, Washington, Landslide Technology designed a concrete shear pile wall to stabilize the upper slide and a cantilevered road section to support the outer lane and road shoulder.
