Police for the first time will conduct a second layer of security screening at the Times Square New Year's Eve festivities this year, New York City officials said Tuesday.

Beyond the usual screenings at access points to the event, “mobile screening teams” will patrol the viewing area for the world-famous ball drop as part of these additional security measures on Wednesday into early Thursday, according to authorities.

“The secondary screening is something that is net-new this year,” NYPD Commissioner Jessica Tisch said at a press briefing Tuesday. “It's based on what we've learned over the past year and what we've seen throughout the world in the terrorism space."

"If we see anything that looks suspicious, we will have teams in place to do appropriate screening," she added.

Tisch and Mayor Eric Adams said there are currently no credible threats to the celebration. He said officials will have “zero tolerance” for people who interfere with the event or engage in other “disorderly behavior” across the city heading into the new year. Thousands of police officers will be on duty around Times Square.

Officials urged revelers to use mass transit to get to and from Times Square, where an estimated 1 million people are expected to gather. If you’re planning to attend the festivities or travel through Manhattan on New Year’s Eve, here’s what you need to know.

Bulked-up security

The NYPD will deploy more police officers at the Times Square access points on Sixth and Eighth avenues this year than it did last year, authorities said. This includes counterterrorism officers and other specialized units, such as emergency services, canine units and bomb squad and heavy weapons teams, along with helicopters and drones.

There will also be teams dedicated to responding to any pickpocketing or hotel incidents in the area, Tisch said. NYPD personnel will also watch fixed and mobile security cameras, while intelligence teams will monitor social media for potential threats.

Accessing Times Square

Viewer entry points open at 3 p.m. on Wednesday and will be located on West 45th, 49th, 52nd and 56th streets at Sixth and Eighth avenues, officials said. They will close as those viewing pens reach capacity, Tisch said.

Street closures

The event will start disrupting traffic in the area early Wednesday morning. Detours will be in place from 42nd to 49th streets between Seventh Avenue and Broadway starting at 2 a.m. and continuing through the rest of the day, according to officials. Nearby parking garages will shut down at 11 a.m. and trucks will also be restricted in the area starting at that time. For a full list of street closures, check out the city’s website.

What to bring, and what not to bring

Officials advised spectators to dress warmly for the event, since cold temperatures are expected. Viewers will not be allowed to bring certain items into viewing areas, including backpacks, large bags and coolers, picnic blankets, chairs, alcohol, drones, laser pens, umbrellas and any other bulky items that can obstruct people’s views, according to the NYPD.
