Operation of the Storm Surge Barrirer

Trusses

The trusses, each 240 metres in length, are a prominent visual part of the Storm Surge Barrier. Their function is to transmit directly to the ball-joint the loads exerted on the retaining walls in the closure process. During closure the truss will ride up and by approximately 40 centimetres into a camber, levelling out again when the load eases.
