The Howland Hook Marine Terminal, operating as Port Liberty New York, is a container port facility in the Port of New York and New Jersey located at Howland Hook in northwestern Staten Island, New York City. It is situated on the east side of the Arthur Kill, at the entrance to Newark Bay, just north of the Goethals Bridge and Arthur Kill Vertical Lift Bridge. Built by American Export Lines, the site originally housed a B& O coal dumper, which was completed in 1949.
