Transportation Assistance for Olympic and World Cup Cities Act of 2025

This bill provides federal funding for transportation projects in cities hosting major international sporting events like the Olympics, Paralympics, or FIFA World Cup. It authorizes up to $50 million annually for grants to states, tribes, and local governments (or their planning organizations) to fund permanent transportation infrastructure and planning within 100 miles of the event site, excluding temporary facilities. The bill also mandates studies by the Commerce Department to examine how hosting these events affects international and domestic travel, tourism business revenue, and employment, with reports due 180 days after the events conclude. These provisions directly support cities bidding to host or already hosting such events, focusing on long-term transportation needs and economic impact analysis.
