Definition & Explanation

Unlike general federal appropriations, the Highway Trust Fund (HTF) is a dedicated U.S. federal fund financed through excise taxes on gasoline and diesel. It funds construction, rehabilitation, and maintenance of the Interstate Highway System, bridges, and other federally supported road networks that carry the bulk of American overland freight. Carriers and logistics operators benefit indirectly: well-maintained infrastructure reduces vehicle wear, shortens transit times, and improves supply chain predictability. The long-term solvency of the HTF is a persistent policy debate, as rising fuel efficiency in trucks and passenger vehicles alike continues to erode the fuel tax base.
