LOUISVILLE, Ky. — The Transit Authority of River City (TARC) is offering all-day fare-free service for Thunder Over Louisville on Saturday, April 20. 

TARC has designated five post-Thunder boarding stops within downtown Louisville to help get home spectators as quickly as possible. The stops will be available for passengers to board immediately after the event and will be the only downtown boarding options, the agency said.

To improve frequency of buses and meet passenger needs, an additional 68 buses will be added to Saturday's service, along with a shuttle service from Shawnee Park to Union Station.

TARC said passengers traveling to and from southern Indiana should know buses on routes #71 (Jeffersonville-Louisville-New Albany), #72 (Clarksville), #73 (West Louisville-River Ridge) and #74 (Chamberlain Ln-River Ridge) will not make return trips to Indiana after 8 p.m. because of bridge closures. Non-cross-river Indiana service will continue.

The agency added some regular routes may be delayed or detoured because of heavy pedestrian traffic and police barricades. It encourages passengers to plan their trips in advance. Passengers will not be able to load fare to their MyTARC cards on the bus because of the fare-free service but can still do so online.
