This bill aims to make highway funding fairer for fast‑growing states. It lets the Department of Transportation give extra federal highway money to any state that has gained population since the last national census, in proportion to how much it grew. These increases can start in the first fiscal year after the bill becomes law.

It also orders a study to update how highway dollars are divided. The Department must consult state transportation departments and local governments, check if the current method fairly matches funds with taxes paid by highway users and meets national goals, and then recommend a new formula with clear factors and weights. A report to Congress is due within 90 days of enactment.

• Who is affected: States with population growth; state transportation departments and local governments (including metropolitan planning organizations)
• What changes: The Department may give extra highway funds based on population growth; a modernization study will propose a new, fairer funding formula
• When: Extra funding can begin the first fiscal year after enactment; the study’s report is due within 90 days of enactment
