EDF – Dismantling of water transportation suspension bridges

Dismantling of water transportation suspension bridges et and passage through irrigation canal using sump pump



In the early 1960s, the construction of the EDF canal, south of Sainte Tulle (04) required metal water transportation bridges to be built in order to ensure the continuity of the various irrigation canals that the EDF canal passed through. The two structures are suspension bridges spanning 115 metres. As a result of the various assessments which revealed the need to dismantle these water transportation bridges, in view of their condition and the fact that they are coated with lead paint, DIADES carried out the dismantling project, including the study of a specific phasing program, and the passage of water through the canal using a sump.
