Webcams are proving the success of special deer underpasses installed by the Wyoming Department of Transportation along U.S. Highway 30. Approximately 14,000 mule deer cross the highway each year in their migration from winter to summer ranges. The number of deer-vehicle collisions had gone down after the underpasses were created, but visual proof came from new webcams which captured on “film” 800 deer, a few antelope and a bull elk using the underpasses in a one-week period.
