The Sturt Highway will receive a number of upgrades aimed at preventing road crashes and protecting against roadside hazards in a $12 million project.

The Newell Highway at Gullifers and Alleena, Goldfields Way at Barmedman, and Burley Griffin Way at Ariah Park will see upgrades.

Deputy Prime Minister Michael McCormack said the $408 million statewide road funding blitz was about economic stimulus as well as road safety.

"This investment won't just save lives, it will also provide a shot in the arm to local economies as we come back from the COVID-19 recession, with these projects expected to support many local jobs," he said.
