　　Though Alberta's Banff National Park is home to a large and healthy wildlife population, it also welcomes about 3.5 million visitors every year. Besides, 4.5 million humans drive through without stopping, all passengers on the busy Trans­Canada Highway that cuts through the park. That's why roadkill (animals that have been killed by cars on the road) was a common sight on the world's longest national road.

　　Banff first put up wildlife fencing on each side of the highway. Then, since 1996, they've opened six wildlife overpasses and 38 underpasses, which have allowed for more than 140,000 wildlife crossings.

　　Though these crossings are normally closed to all humans, as a tourist I was lucky to be allowed to see Banff's Red Earth Overpass with road ecologist Trevor Kinley. As a project manager with Parks Canada, he told me that so far, they have recorded 10,000 safe animal crossings on this overpass alone. That's 10,000 animal lives saved and a whole lot of roadkill prevented.

　　Labib Salama, an animal lover, worries that forcing so much wildlife into using just a few bridges and tunnels (passages under the ground) is putting some animals' lives into danger. They probably become easy meals for their natural enemies on either side. However, the truth is that there are no more killings around the crossings than there are anywhere else in the park.

Walking over the Red Earth Overpass, I was surprised how natural the area seemed. The noise disappeared, as did the road. The forest has filled in the area so that anyone crossing would really have no idea they were crossing a main highway. Along the way, I found the fresh tracks of black bears, grizzlies, wolves, elk, deer, and marten. Somehow, all these animal tracks made me so happy, knowing that they were passing safely under and over the longest road in Canada.
