The Grevelingendam was constructed between 1958 and 1965 as part of the Delta Works and connects Goeree-Overflakkee with Schouwen-Duiveland. The Grevelingendam protects against high water and the dam has reduced the flow in the Grevelingen, the Haringvliet and the Volkerak , so that the Haringvlietdam , the Brouwersdam and the Oosterscheldekering are not overloaded.
Why was the Grevelingendam built?
- The Grevelingendam, together with the Brouwersdam, closes off the Grevelingenmeer , the largest saltwater lake in Western Europe (11,000 hectares), from the North Sea .
- The dam has created new nature because 3,000 hectares of land has been permanently drained.
- The dam also has a traffic function: the N59 runs over it.
The Grevelingendam was built with the aid of a cable car that dumped concrete blocks into the sea.
