The Western Scheldt in the province of Zeeland in the southwestern Netherlands, is the estuary of the Scheldt river. This river once had several estuaries, but the others are disconnected from the Scheldt, leaving the Westerschelde as its only direct way to the sea. It is an important shipping route to the Port of Antwerp, Belgium. Therefore, unlike the other sea arms, it is not closed by a dam as part of the Delta Works. Instead, the dykes around it have been heightened and reinforced.
