It is estimated that up to one million animals are killed every day on the roads of the US alone. To reduce these numbers as much as possible, as well as make roads safer for vehicles and preserving natural animal habitats, wildlife crossings have long become a common feature of highways in North America and Europe, as well as spawning in other parts of the world.
The first bridges for animals over roads were built in France in the 1950s, and the longest one in the world, called the Natuurbrug Zanderij Crailoo, can be found in the Netherlands and is over half a mile long!
Wildlife crossings can take the form of underpass tunnels, viaducts, overpasses (for large or herd-type animals); amphibian tunnels, fish ladders, canopy bridges (for monkeys and squirrels); tunnels and culverts (for small mammals such as otters, hedgehogs, and badgers); and green roofs (for butterflies and birds).
