 If you've driven through Sublet County recently, you likely drove through one of the two wildlife overpasses that frame the area landscape. The overpasses are the first of their type in Wyoming and are believed to be the first designed specifically for pronghorn. The overpasses are strategically located near Trappers Point, west of Pine Dell. The location of the overpasses provides connectivity for pronghorn as they make their historic and epic migration to and from their seasonal ranges. The ranges and distance from 72 to 160 miles each way, which is the longest pronghorn migration recorded. It is estimated that 1,500 to 2,000 pronghorn make the journey each spring and fall. The overpasses were designed to replicate the surroundings. On top of the structures is soil that has been planted with native grasses and shrubs. Additionally, earthen berms line both sides to block the view of the highway. An 8-foot tall fence was constructed on top of the berms to prevent animals from accidentally jumping off. The Wyoming Game and Fish and the Wyoming Department of Transportation asked the public to respect the space of the wildlife and to not recreate on or near the overpasses.
