How Is Massachusetts Using IIJA Funding? Explore the Map
The Infrastructure Investment and Jobs Act (IIJA) gave states a major opportunity to invest in safer, cleaner, and more connected transportation systems. This interactive map, created by Transportation for America, lets you explore how Massachusetts has spent nearly $5 billion in federal IIJA funds—project by project, across the Commonwealth.
To explore the map:
- Select the filters on the left-hand side to sort projects by type—like public transit, highway expansion, bus electrification, and more.
- Click on any project icon to learn about its location, scope, and funding level. Statewide projects are grouped together under a separate bounding box.
(Note: The map reflects reported obligations, meaning funds that have already been committed to the state.)

The IIJA gives states a chance to make real progress on climate, safety, and equity. Through programs like Carbon Reduction, Reconnecting Communities, and Safe Streets and Roads for All, there’s a clear opportunity to repair past harms and build a transportation system that works for everyone. This map helps track how Massachusetts is using that opportunity—and where there’s still work to do.

What we're seeing so far:
Most of the projects are centered around Boston, with a few in Framingham and Nantucket. This highlights ongoing challenges for regional transit authorities across the rest of the state.
Many communities, especially places like Springfield, are still seeing disproportionate investment in highway maintenance and expansion, while lower-cost active transportation projects remain underfunded.
Despite the potential in places like the Berkshires and North Adams, few bike or pedestrian infrastructure projects have been supported with IIJA dollars.
While funding is still uneven, EJ communities like Pittsfield, Lawrence, New Bedford, and Springfield have received significant federal support for public transit. One of the largest investments overall was the $1.7B Cape Cod Bridge Replacement Project, along with several multimillion-dollar transit projects across the state.
Just four LDV projects were funded—two statewide and two local—with modest amounts. This suggests we’re not yet on pace to meet Massachusetts’ EV adoption goals by 2050.
