12:52 PM. Near Madison Square park on 23rd & 5th Avenue. 

Around 9:45AM United States Port of Authority that oversees the operations of all bridges and tunnels in New York City has barred access to Manhattan island to all non-emergency vehicles. By the time this photo was taken virtually all traffic had stopped all across Mid and Lower Manhattan.

New Yorkers had to go by foot to a nearest open to pedestrians bridge. Here you see them walk South towards the Brooklyn Bridge on the other side of which they would be taken home by public transportation.
