This legislation, known as the "Active Transportation Infrastructure Investment Program Reauthorization and Improvement Act," aims to reauthorize and improve the Active Transportation Infrastructure Investment Program (ATIIP). It specifically amends the Infrastructure Investment and Jobs Act to extend the program's funding. The bill authorizes an annual appropriation of $250,000,000 from the Highway Trust Fund, excluding the Mass Transit Account, for each of fiscal years 2027 through 2031 . These funds are designated to support the ATIIP and will be available for obligation. A crucial provision ensures that these funds will remain available until expended and are explicitly non-transferable , providing dedicated and sustained support for active transportation projects.
