According to Crain’s New York Business, at the recent Massey Knakal Brooklyn Real Estate Summit, Daniel Levy, head of CityRealty, proposed a system of aerial tramways, similar to the existing Roosevelt Island Tramway, that would connect Brooklyn to Manhattan as well as linking various places along the Brooklyn and Queens waterfronts. One segment of the proposed tramway, called the East River Skyway, would connect the Brooklyn Navy Yard to DUMBO (although the photo below shows it stopping at Fulton Ferry Landing), and from there go across the East River to the South Street Seaport. Other segments would connect the Navy Yard to Williamsburg, Williamsburg to the Lower East Side, Williamsburg to Greenpoint, Greenpoint to Long Island City, and Long Island City to Roosevelt Island, where it would connect to the existing tramway between Roosevelt Island and Manhattan.
According to the photo map above, the segment linking the Fulton Ferry Landing to the South Street Seaport and to the Navy Yard, shown in red, would be the third, and final, phase of the tramway’s construction.
