US-50 Big Horn Sheep Canyon, Fremont County, Colorado. A Rockfall Mitigation Case Study

US-50 extends west to east in Colorado from Grand Junction to Pueblo and beyond traversing through the rugged terrain of the Central Rocky Mountains and is lined with steep natural and constructed rock slopes. A rockfall mitigation analysis and design was requested by the Colorado Department of Transportation (CDOT) for an existing rock slope on US-50 between MP 242.2 and MP 242.6 near Coaldale in Central Colorado. The CDOT Rockfall Hazard Classification System identified a 2,100-foot long slope along US-50 in Central Colorado because of blind corners, limited rockfall catchment, high traffic volumes, and multiple objective hazards. Through discussions with CDOT, geologic mapping of the rock slope, and stability analyses, Kleinfelder provided a range of recommendations for stabilization and mitigation of rockfall hazards from the rock slope. During construction, Kleinfelder worked closely with CDOT to monitor construction and provide field engineering consultation where necessary.
