The Wyoming Dept. of Transportation and the Federal Highway Administration needed to construct a new bridge pier in the Shoshone River, 13 miles east of the main entrance to Yellowstone National Park. Water quality was a top priority.

Two 4' x 100' AquaDams® were used to isolate the work area. Since the amount of fall in the river is so great, the work area did not have to be completely enclosed. Excess water merely drained off. The first AquaDam® was bent to curve around the work area. The excavated hole had to be kept dewatered using a pump.

The water is moving fast due to the construction of the stream bed and the rapid drop in elevation. A great amount of time was spent rock-picking directly in the path of the unrolling AquaDam® to ensure that the best possible watertight seal would be formed. AquaDams® can seal remarkedly well even over rocky terrain.
