We are working on improving our communication on the construction of the new sea lock at IJmuiden and need your help to find out how we can improve our information service. That is why we invite you to participate in an online survey. The survey will take approximately 10 minutes of your time and will provide us with a wealth of information. Thank you for your cooperation!
