The Trappers Point – Green River route in Wyoming is last remaining corridor of the pronghorn. The dense concentration of game, coupled with increased traffic due to rapid expansion of the oil and gas industry on the Mesa and growth in and around Pinedale, has led to extraordinarily high numbers of animal-vehicle collisions on this stretch of U.S. 191, with significant loss of property and life (both human and pronghorn). The Wyoming Department of Transportation built an overpass for pronghorn over U.S. 191 at Trappers Point. This project was done in cooperation with several state and federal agencies and local ranchers and residents. It includes a network of underpasses and one other overpass across U.S. 191 between Pinedale and a point about 15 miles north of Daniel Jct., along with a network of wildlife fencing and gates to channel animals to specific crossing points. The Trappers Point overpass basically re-connects the northern end of the Mesa with the uplands around Cora Butte, and to pronghorns, it appears identical to the surrounding landscape.
