An October 2011 landslide destroyed 0.3 mile of SR-14 in Cedar Canyon, Utah, leaving the road impassable and limiting access to nearby tourist communities. The landslide also cut off Cedar City from many of the recreational sites up the canyon, including Brian Head and Duck Creek Village. Residents and travelers had to detour 40 to 60 miles while the highway was blocked by debris. Kiewit rebuilt the road by excavating and embanking 700,000 cu yd of rock and dirt, surfacing and striping the roadway, building a new concrete barrier and guardrail, adding drainage improvements and creating a new mechanically stabilized earth wall.
