Original Afsluitdijk construction (1927-1932)
The Afsluitdijk was built between 1927 and 1932 as part of the Zuiderzee Works, closing off the Zuiderzee from the North Sea and creating Lake IJsselmeer. The 32-kilometre dike was a landmark of Dutch hydraulic engineering.
The dike ended the threat of flooding from the Zuiderzee and created a freshwater lake for agriculture and drinking water.
The Afsluitdijk has protected large parts of the Netherlands for over 90 years, but its original discharge sluices reached the end of their technical life.
The current project upgrades the same dike built in 1932, replacing the original sluices and adding pumping capacity for a changing climate.
