Augusta Highway

The Augusta Highway is the part of Australia's ring route (Highway 1) located in South Australia between Port Wakefield and Port Augusta. It was named Augusta Highway in 2011, and was formerly known simply as Highway One[2] and also as the Princes Highway, despite not being continuous to the Princes Highway in the southeast of the state.

Highway system

Following the 2018 South Australian state election, upgrades were announced for both ends of the Augusta Highway. At the northern end, the Joy Baluch AM Bridge across Spencer Gulf at Port Augusta is to be duplicated to improve safety for both local and highway traffic. At the southern end, the intersection with the Copper Coast Highway is to be grade-separated, along with duplicating Port Wakefield Highway through Port Wakefield. The contracts for detailed design and construction of both projects were let in March 2020 to the Port Wakefield to Port Augusta Alliance, a consortium of CPB Contractors, Aurecon and GHD Group. Both are expected to be completed in 2022.[3][4]
