The Australian and South Australian Governments have opened the tender call for an early works project on the intersection of Sturt and Marion roads.

The $3 million upgrade will reduce travel delays and boost the productive capacity of the local network.

This project will also provide an alternative option for motorists when major construction begins on the Darlington Upgrade later this year to streamline the flow of traffic.

The $620 million Darlington Upgrade will slash travel times for tens of thousands of motorists, boost freight efficiency and support about 370 jobs during construction.

Approximately 69,000 vehicles use the intersection each day.

The intersection will be expanded to include an additional right hand turn lane from the east on Sturt Road and there will be two right turn lanes, one left turn and two through lanes from the west on Sturt Road.

Left and right turn lanes on Marion Road will also be extended for traffic coming from the south. These changes will reduce the delays for all traffic at the intersection and boost capacity.

Tenders will be conducted in line with the State Government’s Industry Participation Policy, which assists small and medium South Australian businesses to win government contracts.

Construction on the upgrade of the Sturt and Marion road intersection should start in mid-October and be completed by the end of this year, weather permitting.

The Australian and South Australian Governments have committed a joint $1.5 billion to ensure the Torrens to Torrens and Darlington Upgrade projects are delivered by the end of 2018. More information is available at
