News: Tappan Zee Bridge a Pedestrian Greenway?

There's talk that when a replacement span for the Tappan Zee Bridge across the Hudson River in New York is built, that the original bridge span will be turned into a pedestrian walkway/greenway along the lines of the Walkway Over the Hudson between Poughkeepsie and Highland further north on the Hudson River.

Having been on the walkway several times and really having enjoyed it, I think this a great idea. What do you think?
