Wildlife overpass and underpass will make U.S. Highway 160 safer COLORADO ― Colorado Parks and Wildlife and the Colorado Department of Transportation have partnered with the Southern Ute Indian tribe and several other organizations to construct a new wildlife mitigation project in southwest Colorado. The project, slated to begin this coming spring, will construct several features on U.S. Highway 160 between Durango and Pagosa Springs that will promote safer travel for motorists, enhance safer movement of wildlife, and reduce animal-vehicle collisions along this section of highway. The location of the project will bring a great improvement for that section of highway, explained Scott Wait, senior terrestrial biologist for Colorado Parks and Wildlife.
