Largest Wildlife Crossing in the United States Opens in Colorado

On a stretch of highway between Denver and Colorado Springs, Colorado, wildlife now have a safe way to travel from one side to the other. The Greenland Wildlife Overpass connects roughly 40,000 acres of habitat that were previously disconnected for wildlife.

Though it will be used by a variety of animals, the 200-foot-wide overpass was designed with elk and pronghorn in mind. The overpass is the final piece of a wildlife crossing system that has been in progress for many years and now connects roughly 18 miles of safe crossings for wildlife.
