ADELAIDE, AAP – Work is about to start on 15 new road projects across South Australia with the package worth more than $100 million.

Deputy Prime Minister Michael McCormack says the projects, jointly funded by the state and federal governments, are designed to reduce road trauma and save lives.

“This funding will deliver much-needed lifesaving upgrades including shoulder sealing, rumble strips, works to prevent head-on collisions and barriers to prevent run-off-road crashes,” he said in a statement on Friday.

Among the work, $19.9 million will be spent on the Horrocks Highway between Wilmington and Templars, $18 million on the Barrier Highway between Burra and Cockburn and $17.6 million on the Stuart Highway north of Coober Pedy.

Premier of South Australia Steven Marshall said getting funding flowing and shovels in the dirt on road safety upgrades across the state was going to create jobs and save lives.

“Getting work underway on these projects now means we are delivering safer roads and supporting around 500 local jobs through economic stimulus at a time it is needed most,” he said.
