Port de Bonneuil, Industrial river port in Bonneuil-sur-Marne, France

Port de Bonneuil is an industrial and commercial river port along the Marne, spreading across a large area. The facility has docks, quays, and rail tracks that allow large vessels and complete trains to operate here.

The port was established in 1916 and played an important role during World War I as a supply center. Workers from different countries helped build this strategic infrastructure.

The port's name comes from the Marne loop commune it occupies. From 1964 to the 1980s, the Fnac retail group ran Fnac Marine here, selling boats from the site. Mayor Henri Arlès (1935-1971) fought to keep the port from becoming a marina. Look for the white cylindrical structure with dark lettering beside the silo.

Access to the port itself is restricted, so permission must be obtained in advance. The Marne loop is not navigable upstream between Joinville-le-Pont and Bonneuil: all boats reach the two docks through the Créteil lock. Road access is difficult from the A86, with heavy trucks using the RD60, RD1 and D10; a 2 km link between the RN406 and the port is planned for 2027.

The Marne loop upstream of the port, between Joinville-le-Pont and Bonneuil, is not navigable: every boat must pass through the Créteil lock to reach the port's two docks. In the 1930s a Lancia factory here built Augusta cars renamed Belna for the French market.
