In Colorado, a stretch of highway that once divided open land now carries a different kind of movement above it. The Greenland Wildlife Overpass, spanning Interstate 25 between Larkspur and Monument, was completed in December 2025 and is now part of a broader effort to make roads safer for both people and wildlife.
Built to allow animals to cross one of the region’s busiest corridors, the overpass reconnects nearly 39,000 acres of habitat on either side of the highway. Deer, coyotes, and other species can now follow routes that existed long before the road itself—without entering traffic.
The project reflects a growing shift in how infrastructure is designed in the western United States. Rather than treating highways as fixed barriers, planners are increasingly incorporating crossings that restore ecological connectivity while also reducing the risk of collisions.
This approach has received federal support. As reported by Reuters, the U.S. government awarded $110 million in funding for projects aimed at reducing wildlife-vehicle collisions and improving safe passage across roads. The program spans multiple states and signals a wider commitment to addressing the issue at a national level.
In Colorado, the overpass stands as a working example of that effort. Beyond its immediate function, it represents a change in perspective—one in which movement across the landscape is no longer reserved for vehicles alone.
