Australia’s longest pre-stressed bridge girders have been successfully placed for the Port of Brisbane’s $110 million Port Drive Upgrade project, with the longest span measuring 46 metres long, the company said in its press release.
The work is part of the duplication of the new Lucinda Drive Bridge.
Port of Brisbane Pty Ltd (PBPL) CEO, Roy Cummins said the length was required to safely span the existing Queensland Rail lines, removing the risk and need for construction or future maintenance work associated with the new bridge within the rail line corridor.
Quick facts
Bridge span lengths: 46m (span 2), 43m (span 1) and 14m for (span 3)
Each girder took up to 9 hours to transport and an additional three hours to lift and place
A 630 tonne crawler crane was required to lift each girder
Each 46m girder weighs approximately 140 tonnes and uses 53 cubic metres of concrete
The 79m haulage vehicle includes two prime movers and two Goldhofer hydraulic trailers to transport each girder.
The Super I girders are one of several major innovations for the Port of Brisbane’s project. The project also incorporates the placement of around 50,000 tonnes of EME2 asphalt and is addressing stormwater requirements through its Queensland-first offsite stormwater project in the Lockyer Valley.
The Port Drive Upgrade project is also targeting an ‘Excellent’ rating for ‘Design’ and ‘As Built’ with the Infrastructure Sustainability Council of Australia (ISCA).
