MnDOT and the Infrastructure Investment and Jobs Act (IIJA)

On Nov. 15, 2021, President Biden signed the Infrastructure Investment and Jobs Act (IIJA) into law. Also known as the Bipartisan Infrastructure Law, this was a significant five-year transportation bill (2022-2026) that increased funding levels and introduced numerous new grant programs. It aimed to redefine transportation infrastructure and prioritize health and community-focused outcomes.
IIJA funding
IIJA funding comes to Minnesota through two primary ways: formula and competitive grants.
- Formula funding: 90% of highway funding will be given to states through formula programs. These formula grants provide predetermined funding to states based on a number of factors like population and size. Minnesota has been apportioned $4.8 billion for highways for five years. An additional $300 million is allocated over five years specifically for formula bridge funding. Core highway programs have been kept intact, such as the following:
- National Highway Performance Program (NHPP)
- Surface Transportation Block Grant Program (STPBG)
- Highway Safety Improvement Program (HSIP)
- Congestion Mitigation and Air Quality (CMAQ)
- Competitive grants: In addition, organizations around the state now have the opportunity to compete for billions of dollars through various competitive grant programs. New formula and grant programs cover a wide range of initiatives and projects, including the following:
Technical Assistance and IIJA Match Program
Our State Aid for Local Transportation office provides technical assistance and state funds to local and tribal governments applying for competitive federal grants. Through the IIJA Match Program, we were able to provide $202.4 million in IIJA match funds for 85 transportation projects across the state.
Current projects
MnDOT projects funded by either formula dollars or competitive grants will be included in our four-year list of projects, the State Transportation Improvement Program (STIP).

Upcoming reauthorization
The IIJA is set to expire on Sept. 30, 2026. The House and Senate transportation committees have already begun their work on the next reauthorization bill. They hope to pass the next transportation reauthorization before the current law expires.
