wildlife bridge

Fauna crossing structure

A wildlife bridge is a vegetated overpass spanning a highway or railroad, allowing animals to cross safely between fragmented habitats.

Also called a wildlife crossing or ecoduct.

These structures reduce vehicle collisions with large animals while maintaining genetic connectivity between populations: The elk herd now uses the wildlife bridge to reach their traditional grazing grounds.
