Security measures across New York and around U.N. headquarters have been raised to the “highest level” for the opening week of the 81st U.N. General Assembly, with road closures, temporary flight restrictions and expanded police and federal operations planned across Manhattan.
The New York City Department of Transportation said First Avenue between 41st and 48th streets will be closed to traffic from Sept. 20 to 26 because of the General Assembly meetings.
Residents have been encouraged to use public transportation as heavy congestion is expected throughout the week.
The New York Police Department, U.S. Secret Service and FBI have established a joint operations center to coordinate security for the event.
Authorities said measures on land, at sea and in the air would create a security perimeter at the “highest level.”
Federal officials also granted New York police special authority to neutralize unauthorized drones.
A temporary flight restriction will be enforced within a two-nautical-mile radius around the U.N. headquarters during the summit.
Officials said cybersecurity precautions would also be strengthened.
New York Mayor Zohran Mamdani said extraordinary security and traffic measures would be implemented across Manhattan during the General Assembly.
Mamdani and his team said this year’s summit had been classified as a “high security risk environment” because of global tensions, expected large-scale protests and the attendance of leaders from nearly 200 countries.
NYPD bomb disposal teams, counterterrorism units, specially trained dogs, and heavily armed officers will remain on duty around the clock across Manhattan.
U.S. Coast Guard units will also conduct continuous patrols on the East River behind U.N. headquarters.
