Infrastructure Investment & Jobs Act

The Infrastructure Investment and Jobs Act (IIJA), also known as the Bipartisan Infrastructure Law (BIL), was signed into law by President Biden on November 15, 2021. The law represents the largest long-term investment in our infrastructure and economy in our Nation’s history, authorizing $1.2 trillion for transportation and infrastructure spending over five years from FY 2022 through FY 2026. Of the total authorized funding, approximately $550 billion is new infrastructure spending above current “baseline” levels (i.e., annual spending levels under existing federal programs/legislation).


At the core of the new law is a five-year reauthorization of the federal surface transportation program and $284 billion for highway, bridge, public transportation, and transportation safety improvements – more than half of the IIJA’s total new investment. But the IIJA is not just a transportation bill. It provides significant new investments for non-transportation infrastructure programs, including:

What Does the IIJA Mean for the Tri-County Region?

For the tri-county region of Clinton, Eaton, and Ingham counties, the IIJA provides more funding for the region’s core transportation programs that address the ways people travel, challenges with congestion, and improvements that can keep all users of the system - including drivers, bus riders, bicyclists, and pedestrians - safe. The law reauthorizes - or maintains - many core sources of funding and also increases funding for four core transportation programs administered by the Tri-County Regional Planning Commission:
