What is where?

The construction of the IJmuiden New Sea Lock is well underway. Sheet pile walls, lock chamber walls, cofferdams, etc. are being raised at the construction site. 

But where are they situated? We have made an overview picture to help you get a proper understanding of where these building elements can be found.

World’s largest sea lock

The world’s largest sea lock is being built at IJmuiden. The project is a cooperation of the Ministry of Infrastructure and the Environment, the Province of North Holland, the City of Amsterdam, Port of Amsterdam NV and the Municipality of Velsen. What is the importance of this new large sea lock for the different partners? These are their answers to that question.

A new ‘front door’ for Amsterdam

Every day, ships with goods and raw materials such as oil, food products, jeans, cars, cocoa beans, animal feed, and fertilizers enter the port of Amsterdam. After nearly a century, however, replacement of the lock has become necessary for technical and economic reasons. In 2019, according to plan, the first ship will pass through the new lock. In this way, we can continue to be among the leading European ports.
