Aurecon, and Alliance partners, CPB Contractors and York Civil, were engaged by the Australian and South Australian Governments to develop innovative design and cost effective construction methodologies for the Torrens Road to River Torrens Road project.
Together with the SA Government’s Department of Planning, Transport and Infrastructure, Aurecon, CPB and York Civil have formed the T2T Alliance to deliver the project.
The expansion of Adelaide’s north-south corridor will decrease travel times and ease traffic congestion for north-south and east-west traffic by providing a nonstop motorway to replace this highly congested section of South Road between Torrens Road and the River Torrens.
Aurecon, along with design and construction partners, developed preliminary design and construction methodologies and a cost effective and innovative design.
The innovative design methodology was developed for the retention systems to the lowered road. This method, while recognising research into the behaviour of Adelaide's unsaturated clays, resulted in a highly competitive design solution for the soil nailed slopes.
The total scope of the project includes:
