Port Jersey is an intermodal freight transport facility that includes a container terminal located on the Upper New York Bay in the Port of New York and New Jersey. The municipal border of the Hudson County, New Jersey cities of Jersey City and Bayonne runs along the long pier extending into the bay. To the north is the adjacent Greenville Yards on a manmade peninsula created in the early 1900s by the Pennsylvania Railroad and Claremont Terminal, once part of the Lehigh Valley Terminal Railway operations.
