A consortium of CPB Contractors Aurecon and GHD, will design and construct the Joy Baluch AM Bridge Duplication and the Port Wakefield Overpass and Highway Duplication works.
Local South Australian company, McMahon Services has been given the opportunity to deliver key aspects of these important works under the Port Wakefield to Port Augusta Regional Projects Alliance which shows the commitment to local and small to medium enterprises to be part of the Alliance.
Port Augusta is known as one of Australia's most strategically important transport corridors, sitting at the heart of the nation's east-west and north-south freight routes.
It is also a hub for South Australia's mineral-rich far north and western regions, with the projected growth of these provinces expected to exert further pressure on this infrastructure bottleneck.
This project will include:
Preliminary planning work has been completed and detailed concept planning work is now underway, which will include further consultation.
The duplication of the bridge will improve road safety and efficiency for all users, improve freight productivity and importantly improve the resilience of this critical road link. It will also address the current bridge speed restrictions and safety for people walking or cycling across the bridge.
Port Wakefield Road typically carries 8,800 vehicles per day, however, this can increase to around 16,000 during holiday peak periods. As a result of high holiday traffic volumes and conflicting traffic movements at the intersection with the Copper Coast Highway, lengthy queues have been experienced causing substantial delays.
The Augusta Highway and Copper Coast Highway intersection north of Port Wakefield is one of the State’s busiest regional road intersections being a national and regional link between Adelaide, Port Augusta and the Yorke Peninsula.
The project will improve traffic flow and reduce congestion for all road users, particularly during peak travel times and public holidays, and improve safety and freight productivity along the National Land Transport Network.
The concept design includes:
The projects are expected to be completed in 2022, improving an important freight and passenger link to access the Upper Spencer Gulf in Port Augusta.
