Clever Design Ensures Pronghorn Migration Survives in North America

For thousands of years, pronghorns have trekked more than a hundred miles through the largest migration corridor in North America. Today, this ancient path is roadblocked by deadly highways and wire fences. The Wyoming Game & Fish Department, together with Wyoming’s Department of Transportation, built an overpass to increase the survival rate of pronghorns and protect their migratory path.NineCaribou Productions’s short documentary captures captivating footage of pronghorns galloping safely over a highway that could have greatly altered the future of the species.

See photos of the migration from National Geographic Young Explorer Joe Riis and read more about the development and construction of the overpass.
