SB 3556, the Wildlife Crossings Program Reauthorization Act of 2025, would reauthorize and expand the federal wildlife crossings program in title 23 of the U.S. Code. The bill authorizes $100 million per year from the Highway Trust Fund for fiscal years 2027 through 2031, with the money available until expended, to support projects that reduce wildlife-vehicle collisions and improve habitat connectivity. It also removes the word “pilot” from the program, signaling that the initiative would become a more permanent part of federal transportation policy.
The bill adds several program changes intended to make funding more accessible and easier to administer. For projects benefiting small, rural, or disadvantaged communities, the federal share would generally be 90 percent, and the Secretary of Transportation could raise that to 100 percent if the applicant cannot afford the nonfederal match or would face significant financial hardship. The bill also allows up to 0.5 percent of annual program funds to be used for tribal technical assistance, including application help and support speeding up the time between project selection and funding obligation, and up to 0.5 percent for federal grant administration.
In terms of legal impact, the bill would amend section 171 of title 23, United States Code, by revising the wildlife crossings program’s structure, funding authority, and administrative provisions. It would not create a new standalone state program, but it would affect how states, tribes, local governments, and other eligible entities can compete for and use federal transportation funds for wildlife crossing infrastructure such as overpasses, underpasses, fencing, and related safety measures. The bill also makes a clerical update to the chapter analysis in title 23.
The general sentiment reflected in the bill’s sponsorship is supportive and bipartisan, with sponsors from both parties and no recorded votes or committee debate in the provided materials. The bill appears designed to build on an existing program rather than overhaul it, suggesting broad policy support for wildlife-vehicle collision reduction, transportation safety, and habitat connectivity. Because there are no transcripts or vote records, there is no documented opposition in the provided context.
Notable points of potential contention are limited, but the main issues are likely to be funding levels, the use of Highway Trust Fund dollars, and the degree of federal cost-sharing. Questions could also arise about administrative set-asides, whether the program should prioritize rural and disadvantaged communities, and how much discretion the Secretary should have to waive matching requirements or provide technical assistance. However, the available record does not show any specific objections from lawmakers or stakeholders.
The bill would amend section 171 of title 23, United States Code, by removing the program’s “pilot” designation, extending authorization for $100 million annually from fiscal years 2027 through 2031, and adding new provisions for higher federal cost shares, tribal technical assistance, and limited administrative funding. It would affect federal transportation grant administration and the ability of states, tribes, local governments, and other eligible entities to finance wildlife crossing projects, but it would not directly mandate changes to state law.
The available context suggests generally positive, bipartisan support for the bill. It was introduced by senators from both parties and referred to committee without any recorded opposition, vote tally, or hearing transcript in the provided materials. The bill’s framing as a reauthorization and improvement measure indicates a consensus-oriented approach focused on continuing an existing program rather than creating a controversial new policy.
No specific points of contention are documented in the provided materials, but likely areas of debate include the size and source of the authorization, the use of Highway Trust Fund money, and the balance between federal and nonfederal cost shares. Additional questions may arise over whether small, rural, and disadvantaged communities should receive preferential treatment, how much funding should be reserved for tribal technical assistance and administration, and how much discretion the Secretary should have to waive matching requirements. These are inferred policy issues rather than recorded objections.
