Transportation Project Accountability Act of 2026

This bill requires states to publicly report annually on major transportation projects (costing over $10 million) included in their statewide transportation plans. States must publish online reports detailing each project's score based on how well it meets state performance goals and national transportation targets, along with projected benefits, selection reasons, and geographic coordinates. The reports must also explain the metrics used to calculate project scores. These requirements apply to all states implementing qualifying projects, aiming to increase transparency and tie project selection to measurable outcomes. The law mandates these reports start one year after enactment and continue annually.
