The Government of South Australia has granted a A$415m ($282.6m) infrastructure package to boost its regional road network.

Both state and federal funds will be used to reduce congestion on roads and increase traveller safety.

The funding includes accelerated federal funding of A$328m ($223.4m) for six infrastructure projects.

The government has announced A$100m accelerated funding for the A$143m SA Rural Roads Safety Package, A$86.75m for the A$125m Port Augusta to Perth corridor, A$75m for A$92m Victor Harbour Road Duplication project and A$50m for A$55m Horrocks Highway corridor.

The Darlington Upgrade and the Flinders Link project have been allocated A$87.5m and A$16m respectively.

The majority of the funds for the projects will come from the federal government.

Prime Minister Scott Morrison said: “By bringing forward these important road projects we will drive jobs, boost the economy and make roads safer while reducing travel times so people can be with their families instead of being stuck in traffic.

“Delivering critical road projects sooner as part of our $100bn pipeline is responsible and considered economic management, in stark contrast to Labour’s daily calls of panic and crisis in their attempt to blow the budget.”

South Australian Premier Steven Marshall said: “Today’s announcement builds on our massive $11.9bn pipeline of infrastructure works over the next four years as we continue to grow our economy and jobs.”

In August, the Government of South Australia announced plans and a concept design for the construction of the new Victor Harbor causeway.

In July, the A$174m Oaklands Crossing grade separation project in South Australia was completed.
