Since the Beartooth Highway serves as the principal access to Yellowstone National Park's northeastern entrance, restoring this stretch of road was vital to the region's tourist-based economies.

As part of the design-build team, Shannon & Wilson's geotechnical engineers and geologists moved quickly to evaluate the damage, devise solutions and complete analyses and designs. Roadway repairs included debris removal, construction of mechanically stabilized earth walls (MSEW), temporary soil nail shoring walls, compacted rock slope embankments, earth embankments, rock cuts, drainage improvements, debris flow training berms, and rock fall and debris flow fences-including the tallest debris flow fence in the lower 48 states. Our innovative engineering solutions were key to successfully repairing this critical highway 30 percent under budget and two weeks ahead of schedule.
