The Itinéraire à Grand Gabarit is a water and road route that has been created in order to allow the transport of the outsize structural sections of the Airbus A380 airliner from their point of manufacture to Toulouse for final assembly. The route was largely created by modifying existing waterways and public roads, with the addition of some new road sections. Specially constructed ships, barges and road vehicles carry the aircraft parts on the route, as traditional transportation methods proved unfeasible. The parts are not handled directly.
