Port River Expressway: road and rail bridges design and construction challenges

The Port River Expressway (PRExy) bridges are part of the multi-stage Port River Expressway project which is an $A270M investment linking South Australia's major port and rail terminals and export enterprises at Port Adelaide with interstate road and rail links to Perth, Darwin and Sydney. The project is a major component of a massive program of transport and infrastructure works targeted to improve South Australia's port and industry-related developments and support the future growth in exports. The single leaf bascule bridges - one for road traffic and one for rail - are the major elements of Stages 2 and 3 of the PRExy project. The construction of these bridges involved the contractor, Abigroup Contractors Pty Ltd, integrating a team of designers across a range of disciplines in America and throughout Australia, managing significant off-site fabrication and developing innovative construction techniques, especially when working over the active waterway in the Inner Harbour. The rail component, Stage 3, was multi-faceted, with an involved scope - several elements were world firsts. The complexity of the project provided challenges which resulted in some innovative engineering solutions, particularly associated with the fabrication, assembly and balancing of the bascule spans and with the rail works. Other challenges involved the geotechnical conditions, pier protection and environmental management considerations.
