This is NOT the week for a leisurely stroll through the Plaza. From Sept. 20 to Sept. 30, Hammarskjold Plaza is on high-security or  lockdown when state officials visit the United Nations during the General Assembly.  Expect marches and  protest groups from around the globe, some with amplified sound. Tudor City Place and East 41st through East 47th streets from First Avenue to Second Avenue will  be closed while the Assembly is in session.

The garden is closed and barricaded. Trash bins have been sequestered behind barricades.

The NYPD will completely close First Avenue between East 34th and East 49th streets to traffic because of the security required when world leaders congregate by the dozens at U.N. Headquarters. Police will also restrict the use of the eastern parking lane of Second Avenue to law enforcement and emergency personnel only.
