The South Brooklyn Marine Terminal (SMBT) is an intermodal shipping, warehousing, and manufacturing complex on in the Port of New York and New Jersey. It is located the Upper New York Bay in the Sunset Park neighborhood of Brooklyn adjacent to Industry City, which lies directly to the south. A recycling and waster transfer facility managed by Sims Metal Management is the major tenant. An auto processing terminal is proposed.
The New York and South Brooklyn Ferry operated a ferry from the Battery Maritime Building (formerly known as Municipal Ferry Pier) to the South Brooklyn 39th Street Ferry Terminal, where rail transfer (to the South Brooklyn Railway) was possible until 1935.
Adjacent to the Bush Terminal it is served by car float and transloading activities of New York New Jersey Rail via the 65th Street Yard which also connects to the Bay Ridge Branch, operated by the New York Connecting Railroad. Rail infrastructure improvements along 1st Avenue completed in 2012 connected the yard to SBMT. Other investments in infrastructure included a new break-bulk rail spur along the 39th Street shed, two new rail sidings for auto rack transloading, and a new rail connection to the SIMS facility at the 29th Street Pier. SBMT is also connected along the South Brooklyn Railway (ROW) to 36th–38th Street Yard. In 2012, the interchange with New York New Jersey Rail, LLC at Second Avenue was refurbished and a new ramp was installed at the 38th Street Yard at Fourth Avenue to allow receipt of new R156 locomotives and other that are delivered on flat cars.
