There were no arrests in the restricted area of Chapel Hill's Franklin Street, but seven of Thursday's 15 alcohol-related emergency calls resulted in people being transported to UNC Hospital, said town police spokesman Lt. Kevin Gunter in a news release.
Gunter said an estimated 30,000 people came to party in a closed-off section of Franklin Street for an event city officials dubbed Homegrown Halloween. About 22,000 attended last year's event.
To manage its annual Halloween festivities, the town imposed restrictions on traffic, parking, transit and alcohol sales again this year.
Part of Franklin Street was closed earlier Thursday evening to give revelers a place to mass. The road reopened shortly after midnight - about an hour after the streets were cleared and cleaned, Gunter said.
Orange County Emergency Medical Services transported seven people to UNC Hospital for further evaluation after receiving 15 calls related to intoxication, according to the news release.
More information about the conditions of those people was not immediately available.
