There's no 16B. I never thought of it, but it could be 16W (my exit).

It has a big curve like the one in the picture you just posted. I never thought to look behind me, but since I use that exit frequently, I will the next time I do.

But if the Statue of Liberty is visible, I think it's too far north to see it. The skyline view from there is pretty much all midtown.

15B maybe, or as MaryCas suggested, one of the Jersey City exits.
