This legislation, titled the "Wildlife Road Crossings Program Reauthorization Act of 2025," significantly amends the Infrastructure Investment and Jobs Act to reauthorize and enhance the existing wildlife crossings program. It formally removes the "pilot" designation, establishing the initiative as a permanent program aimed at reducing wildlife-vehicle collisions and improving habitat connectivity. The bill authorizes substantial funding, allocating $200,000,000 for each of fiscal years 2026 through 2031 to support these critical infrastructure projects. A key focus of the reauthorization is to improve access and support for Indian Tribes . The bill mandates a 100 percent Federal cost share for projects submitted by Tribal entities and allows the Secretary to allocate up to 0.5 percent of funds for Tribal technical assistance , helping Tribes navigate the application process and expedite fund obligation. Additionally, the Secretary may retain up to 0.5 percent of funds for efficient grant administration, including application review and award management. Unobligated funds from any fiscal year will remain available until expended, ensuring continued support for wildlife crossing projects.
