Back to the Bricks officials have decided to end Thursday's Rolling Cruise an hour early.
The annual event begins on Saginaw Street in downtown Flint and attracts hundreds of classic cars.
The 11-mile cruise stretches through Burton and ends in Grand Blanc.
Officials said they decided to end Thursday's event at 9 p.m. instead of 10 p.m. because of "unexpected high turnout" and "minor incidents" that occurred during Wednesday's Rolling Cruise.
All other weekend activities during Back to the Bricks are scheduled to take place as scheduled.
No other details were provided.
