I still remember when these overpasses were first built, there was a lot of scepticism and animals were initially wary to cross. However it's nice to see how much of a success it's become.

Not too long ago I took the wife's family to Banff, we checked out one of the information buildings, they showed a time-lapse video of the various animals that cross (pretty much every type of large mammal in the park). Was very interesting and nice to see.
