The new dual-lane, northbound section of Augusta Highway between Port Wakefield and Lochiel in South Australia is complete.
The $185 million project was jointly funded by the Federal and South Australian governments and is said to significantly improve traffic flow, reduce congestion, and enhance both safety and freight efficiency.
Works included the duplication of the Augusta Highway from Port Wakefield to Lochiel, two new overtaking lanes between Lochiel and Redhill, a new northbound overtaking lane just south of the Horrocks Pass Road and Augusta Highway, junction upgrades, shoulder sealing and pavement rehabilitation.
Key project highlights also included the usage of over 1 million tonnes of pavement material and the laying of 40,000 tonnes of asphalt.
As well as the installation of 80 stormwater crossings, 13 culverts, 12 new streetlights, and nine kilometres of safety barriers.

The newly constructed northbound lanes are now operational, while the existing lanes have been converted to southbound-only traffic towards Port Wakefield.
This development is essential for a section of highway that transports more than 3600 vehicles daily, including 1100 heavy vehicles.
The Augusta Highway Duplication project has been delivered through the PW2PA Alliance, comprising CPB Contractors, Aurecon, GHD, and the Department for Infrastructure and Transport.
