A plan for a 2 million-square-foot skyscraper has been revealed for the last empty World Trade Center lot in NYC. However, it is unclear if this project is related to other reported developments in Midtown Manhattan, including a former office tower at risk of collapse and a possible skyscraper at 346 Madison Avenue. The status of various construction and development projects in Manhattan appears to be in flux, with some sites facing potential foreclosure or conversion to residential use.
