New York City will close streets around Ground Zero on Friday, September 11, as Mayor Zohran Mamdani and NYPD Commissioner Jessica Tisch expand security for the 25th anniversary of the 2001 terrorist attacks.
The two officials outlined the plans at a Wednesday briefing at NYPD headquarters in Lower Manhattan. Vice President JD Vance is among the dignitaries expected at the memorial ceremony, where the names of the dead are read each year. Mamdani urged the public to stay out of lower Manhattan on Friday while the closures are in place, and the commemoration is expected to draw large crowds to the memorial plaza.
The department is also raising its presence for the Jewish High Holy Days, which fall in the same period. Tisch said officers will be posted outside synagogues across the five boroughs and at other Jewish religious and cultural sites. Extra patrols will run through the holiday period, and the mayor said his administration would work to help residents observe the holidays safely.
Tisch said confirmed hate crimes citywide are up 16 percent through the first eight months of the year, and antisemitic hate crimes are up 9 percent. More than half of the city's confirmed hate crimes have targeted Jewish New Yorkers, who make up about 10 percent of the population. She described the figures as deeply disturbing. Hate crimes are "moving in the wrong direction," she said, even as shootings and murders sit near record lows.
Both officials said there were no specific or credible threats to the city, but they urged vigilance through the weekend. The added coverage follows a run of antisemitic incidents in New York, including a man charged with a hate crime after allegedly disrupting Shabbat services at a synagogue. It also fits a wider pattern of tighter security around symbolic dates and large public gatherings.
The 9/11 anniversary remains one of the busiest days of the year for New York's protective services, drawing families, current and former officials, and visitors from abroad to the World Trade Center site. Street closures, vehicle checks, and rerouted transit are routine around the memorial, and the added synagogue coverage stretches those resources across the city at the same time.
