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 — bill text, 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 released text of a proposed five-year surface transportation reauthorization bill on May 17, in anticipation of a markup session scheduled for May 21. The bipartisan Graves-Larsen BUILD America 250 bill totals $474 billion. ETW staff have published initial analysis of the bill’s highway title and overall structure, with additional coverage to follow as markup proceeds.
