This is the turn-off at Banff, Alberta , Canada to the #1 highway to Calgary.
Great picture isn't it?

They had to build the animals (especially the elk)  their own bridge because that was where their natural crossing was. After the highway was built there were far too many animals killed.

It didn't take the animals long to learn that this was their very own bridge!

And you have some people who say 'Animals are stupid'. Oh really....?
