The recently enacted bipartisan infrastructure law, or the Infrastructure Investment and Jobs Act (IIJA), fulfills a crucial component of President Biden’s domestic agenda. This historic legislation contains key funding and policies to finally transform our physical infrastructure for the 21st century. The IIJA also includes Senator Markey’s critical priorities to enhance safety, promote equity, and increase funding for passenger rail, public transit, bridges, roads, clean water, and broadband in Massachusetts. Over the next five years—based on formula funding alone and according to the White House—Massachusetts is set to benefit from more than $9 billion in federal investment. The state can also compete to receive billions more under the infrastructure law’s numerous grant programs. These resources will create good-paying jobs and spur economic growth in every corner of the Commonwealth for years to come.
