New Solutions

While Europe has many, indeed hundreds, of wildlife crossing structures, North America has relatively few. The best-studied and only overpass crossing structures are in Banff, Alberta. However, these structures were not designed specifically for wildlife; rather, they were conventional bridge structures which were adapted. They have proven remarkably successful in restoring ecological connectivity and in improving road safety, but could their capacities expand and the cost of their construction contract with a redesign expressly for their purpose?

New solutions to wildlife crossing infrastructure are intended to reduce the costs and to tailor each type of crossing to the specific species in various landscape contexts. We are also considering new solutions to the construction and material of these structures, as we may need to move, enlarge or downsize them based on changing wildlife movement patterns due to changes in habitats, climate or other factors. In the broadest sense, we aim to capitalize on the potential for crossing structures to tell a story—the story of our renewed relationship with wildlife and landscapes.

“Roads and bridges used to be epic stories of human engineering triumphing over natural obstacles. ARC tells a new story. It’s about our capacity to build public infrastructure with and for nature, as well as people.”
