TransAmerica Corridor I-66 and I-50

Route States

There are 12 states along the TransAmerica Transportation Corridor.

Each state DOT will work with the USDOT and the FHWA to finalize the system, coast to coast.

The Departments of Transportation

The TransAmerica Transportation Corridor organization is currently working with the state DOTS to get new regional PEL studies underway, along with the update to the 1994 TTC study.

In the long term, the executive board of the TransAmerica Transportation Corridor will be composed of at least one resident from each of the 12 states.

A New Infrastructure Bill for a 21st Century Transportation Facility

The current administration tends to favor rural connections over metropolitan transit projects.

President Trump’s long-standing infrastructure approach has favored streamlining regulations to fast-track projects and promoting public-private partnerships. He has supported ambitious construction projects, but has not previously enacted a large-scale federal funding package like the IIJA. AASHTO is preparing for a follow up bill for American infrastructure since the current IIJA expires in September 2026. A new infrastructure policy for America could be designed to finish several major transportation projects, such as the East-West TransAmerica Corridor, the I-49 Corridor, or even the Ports to Plains Corridor.

The Infrastructure Investment and Jobs Act (IIJA)—also known as the Bipartisan Infrastructure Law—expires in September 2026. Here's what we know about what will—or might—come next:

What's Expected After IIJA Expires

A New Reauthorization Will Be Needed
  • The IIJA’s October 1, 2026 expiration date means Congress must pass a new transportation/ infrastructure reauthorization law—often referred to as a “surface transportation reauthorization.”
  • It’s currently too early to say whether the next bill will resemble the broad scope of the IIJA (covering transit, water, broadband, energy, etc.) or focus solely on surface transportation (highways, transit, rail).
  • Committees have already begun drafting and holding hearings as early as mid-2025.
  • As of May 2026, the new transportation bill is titled the Build America 250 Act.
Maintaining Funding Levels Is a Top Priority
  • Transportation industry leaders, including labor groups and engineering associations, emphasize that future legislation must at least match IIJA’s funding levels, especially for surface programs.
  • The American Society of Civil Engineers (ASCE) stresses retaining IIJA-level funding, improving efficiency, safety, resilience, and speeding project delivery.
History Suggests a Real Risk of Delay or Extension
  • Historically, transportation reauthorizations rarely happen on schedule. Many past laws have taken months—or even years—and multiple extensions to renew.
  • Analysts warn that a new bill may not pass by Fall 2026 and could require short-term extensions or result in significant structural changes.
  • Additionally, the federal budget situation (including rising deficits) has already limited Congress’s willingness to approve spending at IIJA scale again.

Quick Summary

Will a new bill replace IIJA in 2026?

Yes—Congress is expected to pursue a reauthorization. As of May 2026, the new bill is called the Build America 250 Act.

Scope of the next bill?

Unclear—it might mirror IIJA’s broad scope or focus primarily on surface programs. The CAFI Coalition is working to provide clear federal formula funding for the High Priority Corridors designated as future interstates.

Funding levels?

Stakeholders urge maintaining or exceeding IIJA investment levels.

Timing?

On-time passage is unlikely; expect extensions or delay.

While there’s broad agreement that a new infrastructure bill is needed, the timing, scope, and funding level remain uncertain. Congress is preparing now, but given past precedents and fiscal pressures, on-time passage by September 2026 is far from guaranteed.
