The storm surge barrier of the Oosterschelde is, without any doubt, the most impressive storm surging structure of the Netherlands.The storm surge barrier, with a total length of three kilometres, would be placed over three channels. It would consist of sixty-five prefabricated concrete piers, among which sixty-two steel slides would be installed. When the slides are open, three-quarters of the original tidal movement is maintained. That should be enough to maintain the environment in the Oosterschelde. The building excavations of Neeltje Jans and Noordland, together with the sandbar Geul, formed the closed part of the storm surge barrier. Neeltje Jans was the island from which the operation was performed. The greater part of the prefabricated elements were built there รข the piers, and foundation mats. The stones, which would be plunged around the piers later, were also stored there. As many parts of the dam as possible were made beforehand, on the mainland.
