Interesting story about over and underpasses in Canada built so wildlife can safely cross a long freeway:

They look, for the most part, like typical pedestrian infrastructure: elliptical or boxy concrete culverts under the highway high enough for a human to pass through, or overpasses that would look entirely familiar to the vehicles passing below. All this highway engineering, though, is meant for the benefit of bears. And cougars, and wolves, and elk.

“We’ve got this important north-south transportation corridor for animals,” Clevenger says of the park, which is located in the Canadian Rockies between Vancouver and Calgary. “But it’s bisected by this important east-west transportation corridor for vehicles.”

Great idea.
