Imagined What it could do
Imagine a great stag carved in white stone, marking the paths where animals have always walked. The city\x27s roads would bend around these paths, or pass beneath them, so that animals could always travel freely.
Real world Roads cut nature in two
Roads split forests and meadows into separate pieces. Animals trying to cross are hit by vehicles, which is dangerous for drivers too. Animals that cannot cross may be cut off from food, water and mates.
Real world Bridges for animals
In Banff National Park, Canada, the Trans-Canada Highway runs through the mountains. Parks Canada built fences along the road and dozens of crossing structures, including tunnels under the road and wide, planted bridges over it. Parks Canada reports that these reduced wildlife collisions by more than 80 percent, and by over 96 percent for elk and deer. Cameras show grizzly bears, wolves, cougars and moose using them, though shy animals can take years to trust a new crossing.
