wildlife crossings
Fauna highway bridges
Wildlife crossings are structures that allow animals to safely pass over or under roads and railways.
Overpasses are typically vegetated bridges; underpasses are tunnels or culverts.
They reduce vehicle collisions with animals and help maintain habitat connectivity for species whose territories are fragmented by human infrastructure: The elk herd uses the wildlife crossing to reach their winter range.
