Spui (river)

The Spui is a small tidal river in South Holland in the Netherlands, connecting the river Oude Maas and the Haringvliet estuary, separating the islands of Voorne-Putten and Hoeksche Waard. Historically, it forked off the Oude Maas at the town of Oud-Beijerland to end in the Haringvliet, but as a result from the Delta Works, its flow has been reversed. The Spui emerged as a result of a levee breach during the, a storm surge that permanently altered the surrounding landscape.
There are no bridges or tunnels crossing the Spui, but there is a car ferry from Hekelingen to Nieuw-Beijerland, and a pedestrian and bicycle ferry between Oud-Beijerland and Rhoon.
