State Highway 9 Wildlife Crossings Monitoring – Annual Report Year 1

This research evaluates the effectiveness of the SH 9 Colorado River South Wildlife & Safety Improvement Project, including two wildlife overpasses, and five wildlife underpasses connected with 10.4 miles of wildlife exclusion fencing in Grand County, CO. The project was designed to improve driver safety while allowing for wildlife movement across the road. This study uses motion-activated cameras and WVC crash and carcass data to determine how successful the mitigation measures are. In addition to the crossing structures, deer guards, escape ramps, pedestrian walk-through gates and the fence end are being monitored. WVC carcasses collected in the completed Phase 1 section of the project area decreased from a five-year average of 31, to a total of three in the winter of 2015/16. These preliminary results document the immediate success of this project in decreasing WVC while providing wildlife connectivity. The research study will continue until 2020.
