Animals bridges, which may also be known as ecoducts or wildlife crossings, are structures that allow animals to safely cross human-made barriers like highways. A wildlife crossing is the broadest term and can include: underpass tunnels, viaducts, overpasses and bridges, amphibian tunnels, fish ladders, culvets and green roofs.
Hooray for these countries!!
