You see a similar idea quite often on the north shore of the St. Lawrence in Quebec. Usually they are underpasses, though, and usually combined with a 8-10', very sturdy fence system to funnel the animals into these crossing points and prevent them crossing the highway. Honestly, I think they are more motivated by preventing human fatalities from moose-vehicle collisions, which are exceptionally deadly, primarily, with the ecological concerns secondary.
- kijin 11y agoSince a riverside highway is usually several meters above the water level, an underpass offers direct access to water. An overpass, on the other hand, would need to come down steeply on the other side, which is not only inconvenient but also very ugly. But I've heard that some species don't like to go through tunnels, because predators might lurk in the dark corners (or something like that). So the architecture will have to adapt to the species it is designed for.
