Highway Funding Flexibility Act of 2025

This bill changes how unobligated funds from two federal transportation programs must be used. It restricts National Electric Vehicle Infrastructure Program funds to highway construction, bridge repairs, wildlife crossing structures, and commercial vehicle parking projects, while blocking prior uses. It also redirects unused charging infrastructure grant funds to states proportionally based on their existing highway funding apportionments. All funds remain available until their original expiration date and cannot replace other state transportation funding. The bill applies to both current unobligated funds and future fiscal year allocations under these programs.
