North America’s Largest Wildlife Overpass Opens for Animals to Safely Cross in Colorado
A newly constructed wildlife overpass in Colorado is now the largest of its kind in North America, offering a safe passage for animals to cross a busy highway. This innovative structure aims to reduce vehicle collisions with wildlife and support the safe movement of animals across their natural habitats.

A Safer Route for Wildlife
The overpass, which spans U.S. Highway 160 near Pagosa Springs, was designed to help animals such as deer, elk, and bears navigate across the road without risking their lives. The crossing is part of a larger initiative to protect both wildlife and motorists in the region.
Colorado Department of Transportation (CDOT) officials say the overpass is 100 feet wide and stretches 200 feet over the highway, making it the largest wildlife crossing in North America. The project also includes fencing along the highway to guide animals toward the overpass and away from traffic.
Reducing Collisions and Saving Lives
According to CDOT, wildlife-vehicle collisions are a significant concern in Colorado, with thousands of incidents reported each year. These accidents can result in injuries or fatalities for both animals and drivers, as well as costly vehicle damage.
- Over 4,000 wildlife-vehicle collisions are reported annually in Colorado.
- Deer and elk are the most commonly involved species.
- The new overpass is expected to dramatically lower these numbers in the area.
By providing a dedicated crossing point, the overpass is expected to reduce collisions and improve safety for both animals and people.
Environmental and Community Benefits
Beyond improving safety, the overpass supports the natural movement of wildlife, helping maintain healthy populations and genetic diversity. It also preserves migration routes that have existed for generations.
Local residents and conservation groups have welcomed the project, noting its importance for the region’s ecology and for drivers who regularly travel the highway.
Part of a Broader Effort
The Colorado wildlife overpass is part of a growing trend across North America to build structures that help animals safely cross roads. Similar projects have been built in states like Utah and California, as well as in Canada, but the Colorado crossing now stands as the continent’s largest.
Officials hope the success of this project will inspire further investment in wildlife crossings elsewhere, reducing risks for both animals and humans.
