The Highway Formula Fairness Act aims to change how federal highway funding is distributed to states. The main goal is to ensure that states receive a fair share of federal funds for various highway programs, based on their contributions to the Highway Trust Fund. Key provisions of the Act include a new method for calculating how much money each state gets for federal highway programs. Starting in fiscal year 2027, the amount allocated to each state will be based on the proportion of highway user tax payments made by that state compared to the total payments made by all states.
