Every $1 increase in federal highway, bridge, and public transit investment under the Infrastructure Investment & Jobs Act (IIJA) will generate as much as $3.60 in economic activity, according to a new analysis from IHS Markit, a global information leader.
ARTBA has transformed the data into an interactive dashboard that allows users to see how IIJA formula funding in all 50 states impacts:
- household disposable income
- state and local tax receipts
- state gross domestic product
The dashboard is available in the Economics section of artba.org, along with the full IHS Markit report.
The $1 trillion IJJA was approved by the Senate 69-30 last month and is pending in the U.S. House of Representatives, where Democratic leaders have pledged to act on it by Sept. 27.
