The Veerse Gatdam is the dam with which the Veerse Gat was closed on April 27, 1961. This created the Veerse Meer. The Veerse Gatdam is the third structure of the Delta Works. The N57 runs over the dam.
The dam is 2.8 kilometers long and connects Walcheren with Noord-Beveland. The dam was partly constructed as an asphalt-covered dike on the Plaat van Onrust. For the remainder, submersible passage caissons were used. For the construction of these caissons, a dock was constructed between Veere and Vrouwenpolder. The caissons contained openings so that the tidal flow could continue during the construction of the dam. This prevented the current from becoming stronger as construction progressed. Only at the end of construction were the gates lowered simultaneously, closing the dam in one fell swoop.
Due to the construction of the Veerse Gatdam, the town of Veere is no longer connected to the open sea. The Veere fishing fleet left for nearby Colijnsplaat just before the dam closed. The Veerse Meer is now a popular water sports resort, especially for windsurfers.
