The design and engineering firm Dialog led the structural engineering and landscape architecture of the overpass, which was funded by Alberta’s provincial department of transportation and is now the first wildlife overpass in Canada constructed outside of a national park. It’s in an area where reported vehicle collisions with deer, elk, coyotes, and grizzly bears happen 69 times per year on average. “The very rough rule of thumb is for every collision that is recorded or every carcass that is seen on the side of the road, you can usually double that number,” says Dialog’s Neil Robson, the overpass project manager and lead designer.
