Road Ecology blog: Barrier for animals, sound and light on top of wildlife overpass, Hwy 69, Ontario, Canada. The barrier keeps the animals from jumping down on the highway below. In addition, the barrier blocks visual disturbance and some noise from the traffic below. In this case, the physical, visual and sound  barrier are all integrated into one.

The overpass has art (drawings of animals) on the side, visible to people traveling the highway. The top of the overpass is landscaped with trees, shrubs, and brush and rock to provide cover for animals. Elk (Cervus canadensis), moose (Alces alces), Black bear (Ursus americanus) and white-tailed deer (Odocoileus virginianus) are among the target species. The overpass has a gradual approach (slope) for animals that approach the structure from the surrounding landscape. The wildlife overpass cost about CDN$ 2.9 million.
