Locations have been identified for the construction of three new overtaking lanes on Main South Road between Myponga and Cape Jervis.

The overtaking lanes are a joint $31.8 million (50:50) commitment from the state and federal governments.

They aim to improve traffic flow and boost safety for all motorists including locals, tourists and heavy vehicles, while also building capacity for future growth.

The three overtaking lanes will be built between Second Valley and Normanville (northbound), Delamere and Second Valley (southbound), and Cape Jervis and Delamere (northbound).

The state government undertook a planning study to investigate potential locations that considered environmental impact, socio-economic impact and other construction challenges.

It says engagement with key stakeholders resulted in more than 190 pieces of feedback showing strong support for the project. 

Road travel times and road safety were the most consistent topics raised.

Concept designs for the overtaking lanes are now being developed with further engagement to be held with key stakeholders and the local community as the concept designs progress.

Minister for Infrastructure and Transport Tom Koutsantonis says the state government is committed to improving safety on Main South Road. 

“It was important we spoke directly with people who use the road so we could better understand the concerns of communities in and around this section of Main South Road.

“Now that we’ve identified the locations, we’ll get on with delivering these overtaking lanes to improve safety and travel times - and reduce driver frustration - along this stretch of road.”
