Conservationists are relieved that migrating animals are using the recently-built overpasses on U-S Highway 191 near Pinedale. The highway cuts across major wildlife migration routes, and vehicle collisions with animals have been a problem in the area for years.
The Wyoming Department of Transportation finished six underpasses and two overpasses for the wildlife last year, inspired by similar structures in Banff National Park. They were the first ever built for pronghorn antelope, which can't jump roadside fences, and they avoid enclosed spaces.
The Wyoming Department of Transportation is trying to determine whether reflectors posted at the side of roads help reduce wildlife collisions.
WYDOT’s Cody Beers says the reflectors are meant to bounce light along the roadside when cars pass, so the animals know not to cross the roads.
“Over the last 20 years there’s been roughly seventy-five thousand documented wildlife-vehicle collisions in the state of Wyoming,” Beers said. “So it’s our hope that we can save lives and save animals’ lives.”
