This fall, the Wyoming Department of Transportation wrapped up construction of six wildlife underpasses and two overpasses along a stretch of highway crossed by thousands of migrating mule deer and pronghorn antelope each spring and fall. The overpasses were built specifically to help pronghorn, who are reluctant to use low, dark underpasses because they rely so heavily on their eyesight to warn them of danger. Photographer Joe Riis visited the overpass at the Trappers’ Point migration bottleneck to learn how it was working. Read my post and view his photos at Patagonia’s blog, The Cleanest Line, to learn what he found.
The Wyoming Department of Transportation funded the first ever wildlife overpass structures, designed and built especially for migrating pronghorn antelope. Just west of Pinedale, Wyo., two overpasses and six underpasses will save the lives of hundreds of mule deer and pronghorn, while averting danger to drivers. Wildlife photographer Joe Riis, who documented the western Wyoming pronghorn migration using motion-sensor triggered cameras, says this overpass project can set an example for helping wildlife migration in other places, too.
