Highway Formula Fairness Act

Introduced: Apr 28, 2025
Standard Summary
Comprehensive overview in 1-2 paragraphs

The Highway Formula Fairness Act would add two main changes to federal highway funding. First, it creates a discretionary, population-growth-based supplemental funding mechanism for states. States that have grown in population since the last decennial census could receive an additional funding amount, allocated in proportion to their growth, at the Secretary of Transportation’s discretion. This supplement would sit on top of the existing formula amounts and would begin in the first fiscal year after enactment. Second, the bill requires a comprehensive highway formula modernization study. The study would evaluate how federal highway funds are apportioned under current law, consider equity and data quality, involve state and local stakeholders (including metropolitan planning organizations), and result in recommendations for a redesigned apportionment method. A report detailing the study and recommendations would be due to Congress within 90 days of enactment.

Key Points

  • 1Creates a discretionary population-growth-based supplement to federal highway funding for states that have grown since the last decennial census, allocated proportionally to growth as determined by the Secretary.
  • 2The discretionary increase is added “in addition to” existing formula amounts, and applies starting with the first fiscal year after enactment.
  • 3Requires a Highway Formula Modernization Study to assess the data and methods used to apportion funds under current law (sections 104(b) and (c)).
  • 4The study must evaluate equity in fund distribution, including tax payments by highway users and contributions from the general fund, and alignment with the goals of title 23.
  • 5The Secretary must consult with state departments of transportation and local governments (including MPOs) and deliver a recommendations report within 90 days of enactment, proposing a new apportionment method and weighting factors.

Impact Areas

Primary group/area affected: State departments of transportation and highway funding recipients, particularly states that have experienced population growth since the last census; federal coordination with states on funding decisions.Secondary group/area affected: Local governments, metropolitan planning organizations, and highway users who rely on federal funding for infrastructure.Additional impacts: Potential re-evaluation of how highway funds are distributed, possible shifts in funding emphasis depending on population growth and new apportionment factors, and increased focus on data quality and transparency in formula calculations. There may be short-term administrative work and implementation considerations as the modernization study progresses and any new formula methods are developed.
