Amsterdam city officials want to invest €105m in building a new sea lock system at IJmuiden, replacing the current complex which dates from 1929.

National government is not planning to replace the locks until 2029, but Amsterdam city and the local port authority say this is far too late because of technical shortcomings. In addition, modern cargo ships are too big for the locks.

The total cost of the project is put at €880m but a substantial part of the funding is set to come from Brussels, the Volkskrant says. The city council funding still has to be approved by councillors.
