The code US NRB belongs to Mayport, a naval and fishing community at the mouth of the St. Johns River in northeast Florida rather than a commercial cargo port. It is dominated by Naval Station Mayport — one of the largest US naval bases — together with a working fishing fleet and a vehicle-and-passenger ferry; the old railway freight dock was abandoned back in 1919. Forwarders with container, RoRo or project cargo use the Port of Jacksonville (JAXPORT) a short distance upriver, where the Blount Island, Talleyrand and Dames Point terminals handle commercial trade.
