The concrete tunnels arching over the highway look like pretty much any other bridge. Today, over 88 kilometers (55 miles) of twinned Trans-Canada Highway in Banff and Yoho National Parks, there are now 48 crossing structures, including 41 underpasses, seven overpasses, and accompanying highway fencing throughout to keep wildlife off the road. Several underpasses were built in the 1980s, and the first overpasses were constructed in 1996-7. A series of over and underpasses offered a car-free route past the road. But while the newly-twinned highway eased congestion, it only increased the risk of animals being hit while crossing the road. Overwhelmed with car traffic from the park, the Public Works department proposed splitting a section of the highway to create more space in the hopes of reducing congestion. For over 20 years now, the solution in Banff National Park has been its wildlife crossings, several dozen bridges that help animals cross the Trans- Canada Highway.
ANIMAL CROSSING HAVEN PARK DRIVER
Not only can these collisions cause harm for both the driver and the animal, roadways that cut through animals’ natural habitats can also cut off migration routes.
These accidents include animals of all sizes, from elk to snakes, and each one takes a toll on the environment. As highway systems have grown in North America, collisions between wildlife and vehicles have become a massive problem.
