Wildlife crossing structures (WCSs), underpasses, and overpasses are widely used for the safe travel of larger wildlife species across roads and highways, reducing wildlife-related vehicle collisions to drivers. WCSs are often expensive to build and maintain, and therefore determining a cost-effective, optimal design is a challenge faced by departments of transportation across the United States and elsewhere. Although much research has been conducted...

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...

This research monitored the effectiveness of a wildlife mitigation project on SH 9 in Grand County Colorado. The purpose of the mitigation was to reduce wildlife-vehicle collisions while providing permeability for wildlife across the highway. 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...

The Western Slope Wildlife Prioritization Study (WSWPS) emerged from a commitment to increased collaboration between CDOT and Colorado Parks and Wildlife (CPW) to address wildlife conflicts on roads. The study's objective involved identifying wildlife highway conflict areas where targeted mitigation could have the greatest impact on reducing WVCs. To meet this objective, the mule deer and elk to make cross-highway movements, particularly during migration...
