What's happening: The U.S. Chamber, in partnership with the American Road and Transportation Builders Association, has launched an interactive state-by-state map showing just how deeply federal transportation funding is woven into every state's economy — and what's at stake if Congress fails to reauthorize it.
Why it matters: Roads, bridges, railroads, and airports aren't just infrastructure, they're the arteries of American commerce. Federal surface transportation funding is set to expire, and the Chamber is making the case that reauthorization isn't optional.
What the data shows:
1. Trucking dominates freight movement in nearly every state, often carrying 70–85% of shipped goods by volume.
2. Structurally deficient bridges remain a persistent problem — Iowa leads at 19.2%, with Louisiana, Maine, and Illinois not far behind.
3. Federal funding accounts for anywhere from 11% to 69% of state road and bridge spending, with rural states most dependent.
4. The network spans millions of road miles, tens of thousands of bridges, and hundreds of airports and waterways in every state
