The Infrastructure Investment and Jobs Act (IIJA) (P.L. 117-58) makes historic investments in our nation’s public transportation infrastructure that will shape our future for decades to come. The Infrastructure Investment and Jobs Act provides more than $108 billion for public transit and $102 billion for commuter rail, Amtrak, other high-performance passenger rail, and freight rail over the next five years. These bold investments in public transportation will help our communities and nation tackle climate change, advance equity, meet growing and evolving mobility demands, and create jobs. With enactment of the IIJA, the public transportation industry is uniquely positioned to address these challenges head on.
APTA’s Smart Guide to Surface Transportation Authorization provides information and resources to aid members in navigating the many aspects of this new law. It includes APTA’s summaries, funding and formula apportionment tables, and detailed section-by-section analyses of the public transit, passenger rail, Buy America, and other important titles of the IIJA. It also includes U.S. Department of Transportation (DOT) formula apportionments, guidance, memoranda, regulations, and competitive grant opportunities. We continuously update the Smart Guide as more information about the IIJA and DOT grant opportunities becomes available.
