Wildlife Overpass
Starting a series on my favorite region, the Parks of Alberta Canada.
From a distance, the grey cement bridge ahead looks unremarkable. Two tunnels on either side of the Trans-Canada Highway arc in semi-circles that end bluntly on the pavement below. But on top, away from passing motorists’ eyes, lies a grassy oasis. Against the odds, pine trees and wildflowers have taken root here, giving the overpass a fringe of greenery. On the edges, wire fencing provides safe passage for roaming animals.
There are underpasses as well along the highway that animals use to cross the highway.
Black bears and mountain lions prefer to use the shadowy, damp tunnels whereas grizzlies and ungulates prefer the open sight lines offered by the overpasses.
There are 48 crossing structures, including 41 underpasses and seven overpasses. Bravo Alberta for this clever and effective safety measure for drivers and animals.
