The Department of City Planning has proposed rezoning the area to allow for a handful of new office towers.
The Municipal Art Society has asked for proposals, and some of the ideas look beautiful.
But they also eliminate the Park Avenue traffic that now rises around the side of the terminal.
The Wall Street Journal says the proposals include a pedestrian halo suspended in the sky between two office towers that would move up and down to give visitors views of the city from different heights.
There's a proposal for an elevated glass walkway and seasonal grasses. And there's a pedestrian plaza with sidewalk cafes and retail.
The proposed rezoning is still in the early stages of the public approval process.
