The city and economy have changed drastically since the TKTS was first proposed and then approved. The stairs still offer a choice photo stop and a center to the square.
I'm quite happy to see the city reclaim roads for pedestrians and bicycles. The sidewalks in New York cannot handle the pedestrian capacity. When this happens roads are widened. I'm very pleased to see it with sidewalks and most encouraged by the additional bike lanes. If we could build dedicated bike paths as they have in Amsterdam - all the better.
