Every September, the UN General Assembly’s high-level week brings heads of state and government from around the world to the United Nations headquarters on Manhattan’s East Side. For about a week, security zones around the UN (along First Avenue in the 40s), frequent motorcade closures, and heavy police presence make Midtown East one of the hardest places in the world to drive. The city typically declares “gridlock alert” days. If you need to move around Midtown that week, plan for major delays, avoid the East Side where possible and use walking and the subway for short hops.

Tips for travelers

  • Avoid the East Side 30s–50s by car when possible.
  • Schedule meetings on the West Side or downtown that week.
  • Allow double the usual time for trips through Midtown, including to LaGuardia and JFK.
  • Plan pickups on accessible avenues rather than inside security zones.
  • Walk or use the subway for short distances.

For delegations and businesses

Delegations, NGOs and companies hosting events that week rely on chauffeured transportation with experienced dispatchers who track closures in real time. Book early — demand for vehicles is extremely high. Read corporate travel and the Suburban in government service.
