Grevelingendam

The Grevelingendam is a dam located in the Grevelingen sea inlet between Schouwen-Duiveland and Goeree-Overflakkee in The Netherlands. The Grevelingendam was the fourth structure constructed as part of the Delta Works. The dam is six kilometres in length. Construction began in 1958 with the aim of delivering it in 1964. Due to several setbacks, the construction of the dam took seven years and it was opened on 1 April 1965 by Minister of Transport and Water Management, Jan van Aartsen. There is a navigation lock at the southern end of the dam near Bruinisse, and nearby a control lock using a siphon system, known as the Flakkeese Spuisluis, which connects the Eastern Scheldt with the Grevelingenmeer. The construction of the Grevelingendam permitted Dutch civil engineers and contractors to gain experience that would be necessary for the Brouwersdam, along with more complicated closure works such as those at the Haringvlietdam, and the Oosterscheldekering.
