Major bridges that move to allow sailing yachts to pass beneath them are causing daily traffic congestion when they open for the boats.

To resolve this problem, Royal Haskoning DHV has invented the Tilting Lock - designed to allow boats to 'submerge' under the bridge instead of it opening for them to pass under.

The Tilting Lock (Kantelsluis) is a floating structure which has two separate water filled channels with space for five yachts at a time. When the lock is level, the water surface in both channels is 4 metre lower than the water in the river.

To start service the lock will tilt in order to raise the level of one of the channels to meet the water level outside the Tilting Lock. The investment for building such a lock is €60 million.
