Aurecon, and Alliance partners, Leighton 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, Leighton 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.
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:
Construction of the Torrens Road to River Torrens project is expected to be completed in 2018.
