Surface transportation reauthorization sets federal policy and funding for highways, transit, rail, safety, and related programs for the next five years. This page tracks how the legislation is taking shape in Eno Transportation Weekly — committee action, the Highway Trust Fund, program structure, and the policy questions that will shape the final bill.

Eno’s ongoing coverage of surface transportation reauthorization in the 119th Congress.

Surface transportation reauthorization addresses many things:

• Federal highway program structure, formula apportionments, and funding levels
• Federal transit program structure and funding
• Highway Trust Fund revenues, long-term solvency, bailouts, and the future of Advance Appropriations
• Safety priorities for roads, rail, motor carriers, and AVs
• Freight policy, multimodal programs, rail funding, and discretionary grants
• Permitting, procurement, and project delivery provisions
• Research, technology, and workforce programs

Each of these areas will face new goals, reforms, and tradeoffs in reauthorization and Eno will be helping you follow along.

The House Transportation and Infrastructure Committee is preparing for markup of its surface transportation reauthorization bill which may come as soon as mid-May. Senate Environment and Public Works has not yet released draft text. Highway Trust Fund solvency, formula program structure, and the future of IIJA-era discretionary grant programs remain among the central policy questions.
