PORT of Brisbane’s $110m Port Drive upgrade project has taken another step towards completion as the longest pre-stressed bridge girders in Australia were put in place as part of the duplication of the new Lucinda Drive Bridge. The longest span is 46m long.
Port of Brisbane CEO Roy Cummins said the length was required to safely span the existing Queensland Rail lines, removing the risk and the need for construction or future maintenance work associated with the new bridge within the rail line corridor.

“Port of Brisbane has worked closely with the Queensland Department of Transport and Main Roads (TMR), the project’s principal contractor, Seymour Whyte, and its designer, Arup, to design and develop the Super I girders, and is extremely proud of such a major engineering achievement,” he said.
Each of the girders took up to nine hours to transport and an additional three hours to lift and place, and each of the 46m girders weigh about 140 tonnes.
Mr Cummins said the girders were cast in Bromelton and required a major transport plan, which was developed with TMR, Seymour Whyte and QPS to transport them to the Port.
“For safety, a 156 km transport route was agreed to avoid built-up areas and ensure the roads travelled could handle such large and heavy vehicles, and a limit was set of transporting only one girder each night,” he said.
“As a result, 13 40m-plus girders took an overnight journey (a total of 13 nights) of up to nine hours on specially-designed and escorted 79m long haulage trucks to the Port of Brisbane. Four other 20 metre girders were transported during the day.”
