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 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.
