South Australia will receive $72 million of federal funding to overhaul the state's notorious Port Wakefield Road, a major highway linking Adelaide to the Northern Territory.
The federal and state governments will work together to deliver the $90 million project, which involves duplicating the road at Port Wakefield and building an overpass for the Augusta Highway.
"When it comes to ensuring that we have better, safer roads, the Commonwealth government is committed to doing just that," Deputy Prime Minister Michael McCormack told reporters on Thursday.
The state government will allocate $18 million to the project, which is expected to be completed in 2022.
It will directly address congestion problems and safety concerns in the Port Wakefield area, Transport Minister Stephan Knoll said.
This project will cut travel times, improve route reliability and boost safety around the Augusta and Copper Coast highways intersection, the minister said.
The announcement comes before the state government on Tuesday brings down its first budget since winning the 2018 election.
