The Harbourside pedestrian bridge is a tied network steel arch. The bridge has significantly long approaches with a curved alignment in plan to allow the pedestrian/cyclist traffic to ascend within grade limi-tations.  The tied arch mainspan is 42m long and crosses railway tracks.  The arch span was stage as-sembled along the side of the railway tracks and lifted as a complete unit using two RT cranes of 250 tons and 120 tons capacity.  Lifting constraints included overhead powerlines, railway tracks and industrial buildings.
