Generous to their Wildlife in Western Canada

Driving along Highway 1 from Banff to Calgary, we passed under about half dozen overpasses that have been constructed to allow the wildlife to cross over the highway.  Miles and miles of fences run along the highway in each direction to direct the wildlife to the overpass.  These overpasses are beautifully constructed.  Each is about 100 feet deep and beautifully landscaped with large rocks, grass and trees.  Quite an expense and undertaking, but one that makes a lot of sense to protect the wildlife and those driving along Highway 1.
