The New Year's Day celebrations are usually overseen by thousands of police officers. Aluminum barriers are erected to accommodate spectators; for the 2020 celebration, attended by a million people, barriers were erected from 38th to 59th Street and from Sixth to Eighth Avenue. Typically, the celebrations create large amounts of waste. The New York City Department of Sanitation estimated that by 8 a.m. on New Year's Day 2014, it had cleared over of trash from the New Year's celebration, using 190 workers from their crews and the Times Square Alliance.
