In June 2022, Yellowstone National Park experienced historic flooding – damaging roads, water and wastewater systems, electrical infrastructure and other critical park infrastructure. To help with the reconstruction of the damaged roadways, GeoStabilization International was awarded two emergency design-build contracts for slope stabilization.
The first works were done on the Old Gardiner Road Bypass at Mammoth Hot Springs, where damage at the Park’s North Entrance, cut off access to Gardiner, Montana. Approximately 20,000 square feet (1860 m2) of pinned mesh stabilized the slope, using our TECCO Green G65/3 to help promote revegetation.
The second included a buildout of approximately 120 linear feet (35 m) of the roadway at the East Entrance Gates adjacent to Middle Creek where flooding caused erosion of the bank and placed US Highway 14 in Wyoming at risk.
