There are stairs and entrances for subway access on both side of 11th in front of the Javits.
The east entrance is kinda hidden by that ugly fountain park thingy
across the street another is just inside the parking lot-Front center- to the right, in front of the Big Sign.
A third is under the Upper front entrance. This one is framed by glass block, and on the walls surrounding the stairs leading down,
the typical white subway tile. They were put in and sealed off ages ago.
These could be for something else but I was told when they were building it that's what they were for?
