Reducing congestion at South Australia's busiest regional road intersection

The work undertaken by the Alliance has improved traffic flow, and reduced congestion, at the Port Wakefield intersection by delivering:

Two lanes in each direction through the Port Wakefield township with provisions for safe U-turn movements
A two-lane carriageway for northbound vehicles through the Port Wakefield township, allowing for improved parking and landscaping opportunities, as well as safer vehicle and pedestrian movements
A second two-lane carriageway for southbound vehicles running behind the service stations. This additional carriageway gives flexibility to allow traffic to run in both directions on one other carriageway in the event of an incident
A realigned Balaklava Road intersection with the new southbound Port Wakefield Highway, allowing for safer turn movements for the large vehicles that often use Balaklava Road
Two new bridges replacing the existing bridge 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, greatly improving safety
The new overpass, opened to traffic in December 2021, removes all hazardous at-grade turn movements at the intersection of the Augusta Highway/Port Wakefield Highway and Copper Coast Highway
Improved parking, urban design and landscaping within the township to increase the attractiveness for travellers to stop and spend time

Augusta Highway Duplication (Port Wakefield to Lochiel) Project

The Augusta Highway is the key road corridor between Port Wakefield and Port Augusta and forms part of the National Land Transport Network, providing crucial connectivity to regional South Australia and interstate. As part of the overall programme of works, duplication of the Highway from Port Wakefield to Lochiel – a distance of approximately 30 km – is being designed and constructed. The key benefits of this project include:

Improving road safety for all road users
Improving freight productivity
Reducing travel times
Improving efficiency and network reliability

The project is being delivered by the PW2PA Alliance and is expected to be completed in 2024.

A suite of smaller regional infrastructure works

In addition to the bridge and highway duplication projects, the Alliance is also undertaking regional road network upgrades that make daily travel safer and easier. These works include planning studies, engineering design and construction.

With heavy road freight anticipated to increase across this region of South Australia in the future, the Alliance is making sure that roads are safer now, whilst also preparing them for higher capacities in the future.
