... The A380’s size means its fuselage and wing sections are shipped via a surface transportation network that includes specially-commissioned roll-on roll-off ships to carry these sections from production sites in France, Germany, Spain and the United Kingdom to the French city of Bordeaux. From there, sections are transported by barge along the Garonne River to the Toulouse final assembly line.
As for other Airbus aircraft programmes, production of the A380 takes place in different sites across Europe. Each site produces completely equipped sections, which are transported to final assembly .
... Starting in Hamburg-Finkenwerder on the River Elbe, the ship loads the front and rear sections of the fuselage, from where they are shipped to the United Kingdom. The wings, which are manufactured at Filton in Bristol and Broughton, Flintshire in North Wales, are transported by barge to Mostyn docks, where the ship adds them to its cargo. In Saint-Nazaire in western France, the ship trades the fuselage sections from Hamburg for larger, assembled sections, some of which include the nose. The ship unloads in Bordeaux. Afterwards, the ship picks up the belly and tail sections by Construcciones Aeronáuticas SA in Cádiz in southern Spain, and delivers them to Bordeaux. From there, the A380 parts are transported by barge to Langon, and by the oversize road convoys of the Itinéraire à Grand Gabarit from there to the assembly hall in Toulouse.
