Port Wakefield Overpass and Highway Duplication
The Port Wakefield Overpass and Highway Duplication Project, is a joint initiative of the Australian and South Australian Governments
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.
A Concept Design was released in August 2018. On 28 January 2019, the South Australian Government announced new design options were being considered, which has resulted in an updated Concept Design, announced in November 2019, taking into account feedback from stakeholders.
The updated Concept Design includes:
- two lanes in each direction through the Port Wakefield township with provisions for safe U-turn movements;
- a realigned dual carriageway through the Port Wakefield township, allowing for increased parking and landscaping opportunities, as well as safer vehicle and pedestrian movements. This will make it safer to build and reduce disruption to motorists during construction;
- a realigned Balaklava Road intersection with the Port Wakefield Highway, allowing for safer turn movements;
- new bridges across the Wakefield River;
- a new two-lane overpass for traffic travelling southbound from the Copper Coast Highway to Port Wakefield, and for traffic travelling along the Augusta Highway to the Copper Coast Highway; and
- the new overpass will remove all hazardous at-grade turn movements at the intersection of the Port Wakefield Highway, Copper Coast Highway and Augusta Highway.
The Port Wakefield to Port Augusta Alliance (PW2PA) a consortium of CPB Contractors Pty Ltd, Aurecon Pty Ltd and GHD Pty Ltd, and DPTI continue to work on the Joy Baluch AM Bridge Duplication and Port Wakefield Overpass and Highway Duplication projects, with design works progressing.
A dedicated PW2PA website is being created to provide up-to-date information on the design, construction activities and the progress of works for both projects. The website will also have information for individuals seeking employment and for businesses wanting to register an interest in the projects. Community members will also be able to contact the project team via an Alliance specific enquiries phone line and email address. These details will be publicised when they are available, which is expected in May 2020.
In the meantime, for all project related enquiries please continue to call DPTI on 1300 794 880 or email DPTI.CommunityRelations@sa.gov.au.

We encourage the community to register for email updates.
There will be no planned community events or information sessions until further notice.
Construction works for both projects are expected to commence in the second half of 2020, and be completed in 2022, weather permitting.
Feedback from the Community Information Sessions
The project team held a Community Information Session on 10 September 2019, at the Port Wakefield Eagles Sports and Community Centre. In total, 285 people attended the session.
The project received a variety of feedback and there were some common themes. There was a lot of general positive support for the project and feedback for further potential improvements for safety, access and traffic efficiency.
Feedback from the community included:
- concerns about access to residents and businesses on the eastern side of Port Wakefield Road; and
- concerns about congestion and space near the existing intersection of Port Wakefield Highway and Balaklava Road.
Following consideration of this feedback, the concept design has been updated. The proposed works now include increased accessibility into Phillips Road from the Port Wakefield Highway, subject to detailed design.
The Australian and South Australian Governments have announced the successful tenderer for the major works contract to form the Port Wakefield to Port Augusta Alliance.
A consortium of CPB Contractors Pty Ltd, Aurecon Pty Ltd and GHD Pty Ltd will design and construct the Joy Baluch AM Bridge Duplication and 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 this Alliance which shows the commitment to local and small to medium enterprises to be part of the Alliance.
Project Time Frames
Major construction for the project is expected to commence in the second half of 2020, with completion expected in 2022, weather permitting.
