A grass-covered bridge spanning six lanes of a busy US highway is helping wildlife cross safely between habitats, while a wider network of crossings and fences has cut animal-vehicle collisions by 91% along a stretch of Interstate 25 in Colorado.
The Greenland Wildlife Overpass, completed in December 2025, connects 39,000 acres of habitat near Larkspur and Monument, south of Denver.
The $15 million structure is designed primarily for large animals such as elk and pronghorn, which often avoid enclosed tunnels.
