 The Hudson Avenue Railroad opened the line in late 1867, from the Hudson Avenue Ferry to Gouverneur Slip in Manhattan south along Hudson Avenue and the Brooklyn City Rail Road's Flatbush Avenue Line trackage on Flatbush Avenue to Ninth Avenue at Prospect Park.The ferry stopped running in early June 1868, and the company asked the Common Council to lay track in John Street and Bridge Street to the Bridge Street Ferry to James Slip in Manhattan.Consent was given later that month, and the new line was opened by August 18, 1868.
