Transportation Assistance for Olympic and World Cup Cities Act of 2025

This bill establishes a $50 million annual federal fund to support transportation infrastructure for U.S. cities hosting major international sporting events like the Olympics, Paralympics, or FIFA World Cup. It provides grants to eligible entities - including host cities, nearby jurisdictions within 100 miles, and transportation agencies - to fund permanent transportation projects (e.g., road improvements, transit upgrades) that aid event logistics or mitigate traffic impacts, but excludes temporary event infrastructure or bid preparation costs. Assistance is limited to the 5-year period before an event begins through 30 days after it ends. The bill directly affects communities selected to host these events and their surrounding regions, ensuring federal support for sustainable transportation planning tied to the events.
