Main South Road and Victor Harbor Road duplication opens, but speed restrictions to remain

A long-awaited road duplication has opened – just in time for Christmas. But speed limits will remain in place for the next month. Find out where.

Summer road trips and escapes to some of South Australia’s most picturesque locations will be easier after the $685m Main South Road duplication opens on Monday.

All four lanes on Victor Harbor Road between Main South Road and the McLaren Vale turn-off will open, followed by the Seaford and Aldinga later this week.

The new Tatachilla and Pedler Creek bridges are open to traffic.

Some speed restrictions will remain in place along Main South Rd and Victor Harbor road for the next four to six weeks until the surface is worn in.

Infrastructure and Transport Minister Tom Koutsantonis said it was great news for “thousands of holiday makers”.

“Around 26,000 motorists travel on Main South Road each day, and around 18,600 on Victor Harbor Road,” Mr Koutsantonis said.

“These duplication projects provide critical infrastructure that will result in safer and faster journeys for motorists and provide a vital boost for local tourism and communities.

“The projects have provided opportunities for local workers, businesses, supply chain partners and contractors, from construction and civil works companies to local bakeries and printers.

“We’ve also worked with local agricultural and viticultural communities to create the infrastructure they need, and the new shared use path being built along Main South Road will provide safer and better access for cyclists and pedestrians.

“It’s fantastic to see these projects reach this milestone, and as minor works, planting and landscaping alongside the roads are finished over the coming months, travelling to, from and around the Fleurieu Peninsula will be a much safer and more enjoyable experience for everyone.”

The two projects included 11.7km of pavement, 99,250 tonnes of asphalt and 5640m of drainage installed.

There was 9km of shared use path also built.

Kingston MP Amanda Rishworth said the road project supported tourism and South Australia’s wine regions.

“This project also supports local farmers, cyclists and pedestrians with its inclusion of a new shared use and agricultural machinery underpass to improve safety and access,” she said.

Some works will continue into 2024 with speed and lane restrictions in place, and some detours.
