How building subways helps build our parks
As work on Manhattan’s Second Avenue subway line progresses, those viewing the massively scaled operation may wonder, “where does all the excavated dirt and rock go?” In the past, the ‘muck’ from expanding subway lines and other construction projects has contributed to the building of Ellis Island, Governors Island and Battery Park City, among other city landmarks – including the expansion of the Manhattan shoreline. Crushed rock from the 7 train extension was used in the construction of Owl Hollow Fields at Freshkills Park on Staten Island and material from the Second Avenue line is being used in the construction of the Ferry Point Golf Course in the Bronx. Material from the Long Island Railroad expansion under the East River was used in Brooklyn Bridge Park. Additional waste is processed and sold for construction and landscaping by private companies.
