Wildlife bridges are special crossings that help animals get across highways safely.
Lush foliage, soil and streams lure bears, deer, moose, panthers and other wildlife over or under busy roadways so as not to get crushed by cars. The crossings aren't just for protection. They also help connect habitats that are broken up by roads.
