BRISBANE’s new Eleanor Schonell Bridge is Australia’s first pedestrian, cycle and bus bridge. The $55 million bridge, which links Dutton Park, five kilometres from the Brisbane CBD, with the University of Queensland at St. Lucia, is designed to carry buses, cyclists, pedestrians and emergency service vehicles. The John Holland Group won the contract to design, construct and maintain the 390m span cable-stay bridge over the Brisbane River. The bridge design includes two twin-column 70m towers supporting a composite steel and concrete deck which is 20m wide, 1.5m deep and 185m long. More than 875t of 350 Grade steel from BlueScope Steel was used to fabricate key sections of the deck for the structure, which was originally known simply as the “Green Bridge”.

This is the first major cable stay bridge built in Australia in the last decade. Engineers devised a modular system for the steelwork, based on the need to alternate between adding cantilevered sections on the bank side then river side of the supporting columns to balance the weight. Delivered to the bridge construction site by road then assembled and checked in a jig before being lifted into position by crane, each 9.6m long steel module weighed up to 24t.
