Wildlife overpasses, green bridges, and ecoducts all refer to structures that have been built over roads to allow wildlife to cross safely to the other side of the road. The bridges are for the animals; the animals walk over the road, and the vehicles go through the structure.
Most of the structures typically have soil, litter, and vegetation on top to provide suitable habitat for a range of different species and species groups. The larger structures are intended for large mammals ranging from ungulates to large carnivores. Here are pictures of some of the most beautiful and interesting wildlife overpasses in the world.
