CIMIC Group company CPB Contractors has been selected by the South Australian Government to deliver the next stage of the Augusta Highway Duplication - Port Wakefield to Lochiel.

Funded by the Australian and South Australian governments, the contract will generate revenue of approximately $132 million to CPB Contractors and is to be delivered under the Port Wakefield to Port Augusta Alliance with the Department for Transport and Infrastructure, Aurecon Australasia and GHD.

The project duplicates the existing Augusta Highway with a new two-lane carriageway, and intersection/junction treatments, between the intersection of the Port Wakefield Highway, Copper Coast Highway and Augusta Highway, and the township of Lochiel.

Work will commence in 2022 and is scheduled to be completed in 2023.
