Project description

In the existing dike between Lelystad and Enkhuizen lies an existing lock named Krabbersgatsluis. This lock crosses the road that is situated on top of the dike by means of a drawbridge. In de holiday season the junction between the road and waterway is a source of congestion for road traffic because the lock is namely used for cruise of private yachts without stroked masts causing a high frequency of opening of the bridge. For navigation the lock is also an obstacle because the passage capacity is not in proportion with the traffic volume which leads to an extended wait for navigation. To avoid congestion a choice is made for a crossing where the road is led under the waterway. The new lock has been constructed on a new artificial island made on the southern side of a curve in the dike.
