A WORLD OF PAIN FOR NYC

UN to wreak traffic hell

The UN General Assembly is back — and with it, bumper-to-bumper traffic.

Bus routes will be disrupted and roads closed — sometimes without notice — generally turning Midtown into a gridlock nightmare all week while world leaders convene at the UN Secretariat Building on First Avenue between East 42nd and 48th streets.

Average car speeds sink to 4 mph during General Assembly week, dragging out a mile drive to 20 minutes, according to city transportation officials. The NYPD is urging people to take mass transit or bike since Midtown traffic is expected to grind to a halt.

President Biden is expected in the city after he attends Queen Elizabeth II’s Monday funeral in London. His speech to the assembly is slated for Wednesday.

Here’s what officials say you should expect through Sept. 23:

Vehicle traffic

Gridlock Alert Days have been designated for Monday to Friday by the city Department of Transportation. Numerous roadways will be closed beginning 10 p.m. Sunday, including First Avenue between 42nd and 48th streets, and 44th to 46th streets between First and Second avenues.

Parking will be permitted on 48th Street between Lexington and Park avenues, 49th Street from First to Fifth avenues, and 50th and 51st streets from Park to Madison avenues. The FDR Drive will be subject to “intermittent,” unplanned closures, while other streets nearby will have fewer traffic lanes. A driver’s best bet is to avoid Midtown entirely.

Bus service

Riders should expect delays on all buses operating in Manhattan, with detours on a number of routes:

Northbound M15-SBS buses will not make stops on First Avenue from 39th Street to Mitchell Place through Friday. M50 buses will begin and end at 50th Street and Second Avenue. Express bus stops will be closed throughout Midtown.

Bike lanes

The city will stage temporary bike lanes on First and Second avenues for the week, as it has since 2019. Neither route requires a detour.

Cyclists northbound on First Avenue will pass a security checkpoint at 39th Street and be able to pedal up to East 49th Street on a temporary bike lane through the First Avenue Tunnel from East 40th Street. The lane will be open around-the-clock.

A temporary bike lane will run southbound on Second Avenue between East 47th and 41st streets until 9 p.m. The existing bike lane is set aside for dignitaries and emergency vehicles. Both streets are “subject to security checkpoints and traffic freezes,” the DOT said.
