Road Crossings for Safe Animal Passage

Roads built by humans often divide animal habitats; animals must cross the road and dodge traffic to get to the land & resources on the other side - this leads to millions of animal deaths each year.

Underpasses have been constructed which allow animals a "subway" under the road. For example, a pilot project, carried out by the Florida Dept. of Transportation, built underpasses for black bears. Their research shows that all sorts of animals were photographed using the safe-passage under the road. This is a simple thing that we can do to help animals traverse our roads safely; animal underpasses can successfully reduce numbers of "road-kill." Underpasses are just one of a great many new kinds of structures and devices that help animals get across our roads! Nowadays, you may hear these structures referred to as "Green Bridges."

The question was 'do the corridors actually work?' And in the last 10 or 20 years, we've started to prove that yes, they do work. ~Nick Haddad
