The one rail link, the Trans-Gabon Railway, connects the port of Owendo with the inland town of Franceville.
Much of the road network remains unpaved, and it primarily revolves around seven "national routes" labeled N1 through N7.
The largest seaports are Port-Gentil and the newer Owendo, and 1,600 km of inland waterways are navigable.
Until the 1970s, Gabon had no permanent railroads, though temporary Decauville rail tracks were in use in the logging industry as early as 1913 (Gray and Ngolet, 1999, pp.102).
Major roads are denoted national routes and numbered, with a prefix "N" (sometimes "RN"): As of 2002, there was one merchant marine vessel, with a gross tonnage of 2,419/3,205 tonnes deadweight (DWT).
