New Sea Lock brought into vision

The construction of the IJmuiden New Sea Lock is now in full swing. Construction began in January 2016 and the new lock will be available for shipping early 2022. From then on, the port of Amsterdam will be accessible 24 hours a day. Until that time, you can follow its construction in pictures and on films on this site.

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 (in Dutch) to help you get a proper understanding of where these building elements can be found.

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.
