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.
