Build it and they will come ...

This is the actual turnoff from Banff to the # 1 highway to Calgary, Canada. They apparently had to build the animals (especially the elk) their own crossing because that is where the natural crossing was and after the highway was built there were far too many accidents. It didn't take the animals long to realize this was their "road". I think the backward/sideways glances would cause just as many traffic accidents - it's not everyday you see 3984 elk crossing above you on an overpass.
