Sea Lock IJmuiden: built for the future

The Port of Amsterdam’s new front door

Thanks to the new sea lock, the Port of Amsterdam is assured of a reliable entrance to the North Sea for a long time to come. With this, we can work together with the North Sea Canal municipalities and other parties in the area to develop the port as a sustainable and circular energy and raw materials hub. That’s how we plan to facilitate the necessary steps towards the sustainability of the economy and our society. Learn more about the exact steps below.

A look back on the construction of the IJmuiden sea lock

Sea Lock IJmuiden is one of the largest infrastructural projects in our country. A structure to be proud of. The lock was commissioned by the Dutch Directorate-General for Public Works and Water Management (Rijkswaterstaat), and built by contractors consortium OpenIJ. It was a collaboration between the Ministry of Infrastructure and Water Management, the Province of North Holland, the City of Amsterdam, the Municipality of Velsen and the Port of Amsterdam.
