This overpass helps bears cross a highway in Canada.

Bear hair study in Banff proves animal highway crossings work

For three years, researchers from Montana State University spent their summers collecting bear hair. The samples, collected on both sides of the 50 mile stretch of the Trans-Canada Highway that cuts through Banff National Park, prove what the researchers had suspected: wildlife underpasses and bridges were helping enough bears move back and forth across the highway to keep the populations healthy.

The Trans-Canada Highway stretches nearly 5,000 miles acrowss the country, rolling through each of the nation’s 10 provinces and connecting the Atlantic and Pacific coasts. The 100 miles that pass through Banff National Park is a blip in the entire stretch of highway, but a potentially deadly obstacle for the wildlife that live in the park. Demand for a bigger, faster road system prompted a widening of the highway in the 1990s. During construction, engineers lined the highway with fencing and built underpasses and bridges for animals to cross, with the theory they would reduce collisions and provide animals safe passage. However, the decision was controversial as there was little data to backup the hunch.
