Developed collaboratively by a multidisciplinary team of experts, this report summarizes for policymakers the challenges and anticipated benefits of creating a systematic, national network of wildlife crossings.

The report first explores the high cost of wildlife-vehicle collisions and the many challenges to transforming the US road network. For instance, no single agency is responsible for ensuring that animals can move freely across the landscape to meet their needs, so solutions often need to align the efforts of multiple partners. The report then catalogs the anticipated benefits from investing in highway crossings for wildlife.

In addition, the report identifies existing support for wildlife crossing structures and some policy and funding improvements that would further support the deployment of crossings. Finally, it maps out a path forward that advances evolving technological solutions while building upon successful efforts to reduce wildlife-vehicle collisions already underway at the federal, state, local, and Tribal levels.
