It is an icon of our country. A structure spanning 32 kilometres one that has kept the Netherlands safe for over 80 years. That is something to be proud of. A wonder of the modern world, made of millions of cobblestones. Laid one by one by thousands of hands. It was built to keep the sea out and to create additional arable land. The water will always try to reclaim The Netherlands. By building our dikes, we the Dutch, have made it possible to live below sea level. To ensure our future safety we are reinforcing the Afsluitdijk. Once on every 10,000 years a storm can hit unlike any other. That is what the dike will protect us from. In order to drain excess water from the IJsselmeer into the Wadden Sea we are building what will be Europe’s largest pumping station within the dike, which will be ready to pump out water should the need arise. The Afsluitdijk will become a place where safety goes hand in hand with unique innovations. A place where we strive towards achieving sustainable energy. This is where we will harness the inexhaustible power of the current. And we are the only nation in the world that generates electricity from the convergence of freshwater and saltwater. We will be helping our wildlife too with the creation of the Fish Migration River. Fish will be able to reach their natural spawning grounds and habitats. This is what we are capable of: a large-scale, hydraulic work of art that is ready for the future. And that future starts here, in 2017 with the construction of the New Afsluitdijk.
The Afsluitdijk has been protecting the Netherlands from the sea for more than eighty years. However, the dike no longer meets the current requirements for flood protection.
Rijkswaterstaat is therefore going to reinforce the Afsluitdijk (PDF, 1,61 MB). We plan to make the dike overflow-resistant by replacing the outer cladding and will strengthen the sluices and locks. We are also going to install powerful pumps in the sluice complex at Den Oever so that more surplus water can be discharged from the IJsselmeer into the Wadden Sea. The Afsluitdijk’s new pumping station is expected to be the largest in Europe.

The many faces of the Afsluitdijk
The importance of the AfsluitdijkThe Afsluitdijk is from great value for the Netherlands and is being used for safety, traffic across the roads and waters, cultural history, recreation and more. Read more about the importance of the Afsluitdijk.
History and functionThe region around the former Zuiderzee was vulnerable to flooding. There were already plans to build a causeway in the 17th century. In 1916, a combination of a storm at sea and an enormous surge of water from the IJssel caused flooding in large parts of the area around the Zuiderzee. Read more about the history of the Afsluitdijk.
Iconic AfsluitdijkRijkswaterstaat will be strengthening the Afsluitdijk causeway in the years ahead to continue protecting the Netherlands in future against the power of the water. The state and region are taking this opportunity to also give other initiatives space as well. Read more about the Iconic Afsluitdijk
