SA road projects' $145 million boost

SA Premier Steven Marshall says an additional $145m will be spent on state infrastructure projects

South Australian shovel-ready infrastructure projects and urgent road safety upgrades will receive a $145 million boost to help the local economy recover from the COVID-19 pandemic.

Co-funded by the state and federal governments, the additional funding will fast-track infrastructure projects to help bust congestion, improve safety and increase productivity.

Prime Minister Scott Morrison said further investments in infrastructure will play a critical role in the JobMaker plan to rebuild the economy.

"This funding injection means we have brought forward or provided additional funding in excess of $440 million to South Australia in the past eight months," Mr Morrison said.

Premier Steven Marshall said the investment would help create local jobs.

"We have worked very closely with the federal government to fast track funding for these shovel-ready projects which will complement our record $12.9 billion infrastructure pipeline here in South Australia," he said.

SA Infrastructure Minister Stephan Knoll said regional road upgrade would stimulate regional economies and improve road safety.

"We are funding a suite of safety improvements across the state which will include fixing Long Valley Road through localised widening, shoulder sealing, intersection treatments, safety barriers and sight distance improvements," Mr Knoll said.

The federal government is investing $115.6 million, while the state government will fund $28.9 million.
