Times Square will be closed to traffic from 3 p.m. until the end of the celebration. Police will direct party-goers to the different viewing sections, which will run from 43rd Street to Central Park along Broadway and Seventh Avenue.
Backpacks, large bags and alcohol will be banned from the site, authorities said, adding there will be additional DWI patrols and checkpoints throughout the city.
People who leave before the ball drops will not be able to come back to their original viewing spot, police said.
The NYPD said on Tuesday that every officer who graduated on Monday would be assigned to Times Square for the event, and that details are set up in case of any protests at the event.
"People have an absolute right to protest,” NYPD Chief of Department James O’Neill said at a press conference on Tuesday.
