Police were out in full force trying to keep everyone in check.
From scary zombies to Halloween royalty, there were some pretty creative costumes.
Police say the crowd was smaller than last year.
After years of swelling attendance, police have been trying to shrink the event and make it local only.
"Our interest has been to shrink this event and return it to an entirely local event and they've succeeded," said Chapel Hill Police Chief Chris Blue. "Six or seven years ago, we had people driving from all over the state and even out of state, to come to this event and it swelled to over 80,000 people, which was clearly an unsafe and unmanageable condition."
Since 2007, the town has made a concentrated effort to cut those crowds by cutting off parking in downtown, changing bus routes, and closing the street for exactly two and a half hours.
"If you can walk to Franklin Street, you can come," said Blue. "Otherwise, you might as well not try."
They closed the street from 9 to 11:30 p.m. to vehicular traffic.
There were no arrests reported.
