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.

In order to monitor the progress of the construction from the air, drone recordings are made every three months. The recordings made in the fourth quarter of 2019 include the following highlights:

The sand depot of OpenIJ at the western part of the Middle Lock island; the separation of the approach channels to the Middle Lock and to the new sea lock; the guard wall and the dividing wall as part of the flood defence structure; the lock gate chambers of the outer head and the inner head; the removal of the temporary walls in the lock gate chamber of the inner head; the flood defence structure at the location where the road and cycle path will be built; the Lock Operation Centre (SOC) and the local control buildings.
