Ouvrages du Libron (English: Works of Libron) is a structure like no other on the Canal du Midi. It allows the Libron River, near Agde in south-west France, to traverse the Canal du Midi. At the point of intersection, the Libron is more or less at the same level as the Canal du Midi so a traditional aqueduct was not an option. The problem was further exacerbated by the Libron's propensity to flash flood up to twenty times a year. The problem was originally solved by the building of a pontoon aqueduct known as the Libron Raft which utilised a flush-decked barge to protect the canal channel in times of flooding.^[1] However, this was replaced by the present structure in 1855.
