Sean O’Casey Pedestrian Bridge is the successful result of an international competition that required a openable bridge over the River Liffey in Dublin.

The solution is an exciting moveable structure that spans the 100m wide river using two 44m long balanced cantilever leaf structures plus short abutment supported cantilever spans. A range of materials and forms have been used - aluminium decking is supported on a continuous frame of steel circular sections, which in turn are supported by a central cradle of tapered steel sections and tension rods. The cradle is supported on the slewing bearings enabling the twin leafs to rotate on plan thus creating a 33m wide navigation. All aspects of the bridge appear to be well thought through and neatly detailed and should provide interest and enjoyment for engineers and users alike, whether the bridge is open for their use, or being opened for river users.

Overall, the structural solution combines lightness in design to resolve structural forces with efficiency and transparency. The result is a aesthetic and elegant design.
