The annual Bantam Jeep Heritage Festival kicks off Friday afternoon with the invasion into Downtown Butler.
That means some major traffic changes for drivers this evening.
Butler City Police say Main Street will be closed from Wayne to Pearl Streets beginning at 3:30 p.m. They will remain shut down until 10 p.m.
There will also be no parking allowed on Main Street beginning at 2 p.m.
Police say the normal detour will be in play around the city.
Festival officials expect around 1,000 Jeeps to make the trip to Downtown Butler this evening beginning at 6 p.m.
