• Abstract:
  The State Highway 9 (SH 9) Colorado River South Wildlife and Safety Improvement Project in Grand County was designed by the Colorado Department of Transportation (CDOT) and partners to improve motorist safety by reducing wildlife-vehicle collisions (WVC) while providing opportunities for wildlife to move beneath and above SH 9 through wildlife crossing structures. Prior to the project, WVC were the most common accident type on this segment of highway, accounting for 60% of all accidents reported to law enforcement. In response to these concerns and with partner support, CDOT installed two wildlife overpass structures, five wildlife underpasses, 10.4 miles of eight-foot-high wildlife exclusion fencing, 61 wildlife escape ramps, and 29 deer guards to help reduce WVC while providing safe passages for wildlife. This research study evaluates the effectiveness of the mitigation infrastructure through the use of motion activated cameras and analyses of WVC crash and carcass data.
