thru streets- 37th street and lexington, day hours.
On Lexington Avenue between 36th St. and 37th St. You can bet that there are police in the middle of the block after 10am watching for cars dis-obeying the no left turn sign. there is heavy traffic sometimes coming out of the tunnel. there are no turns allowed after 10 am on lexington avenue. use 35th street instead for left turns on lexington.
