The June 5 State Budget will include new funding to deliver critical safety improvements on a notorious section of Main South Road between Myponga and Yankalilla.
The Malinauskas Government will partner with the Albanese Federal Government to deliver a total of $80 million (50:50) over five years from 2025-26, which will include the construction of new overtaking lanes.
Main South Road is a key route connecting heavy vehicles, commuters and tourists from Adelaide to destinations along the Fleurieu Peninsula. The section of road between Myponga and Yankalilla carries around 4,900 vehicles a day.
The road includes many curves and has an undulating environment, which makes overtaking difficult, resulting in delays and driver frustrations that can lead to unsafe behaviour.
Between 2019 and 2023, there were 16 crashes, which resulted in one fatality and five people seriously injured. In 2024, five crashes resulted in four lives lost and two serious injuries.
Upgrades will include the construction of two new overtaking lanes, targeted curve easing and road widening, as well as widening narrow bridges and culverts.
These improvements will increase overtaking opportunities and create a safer environment for all road users travelling to and from the Fleurieu Peninsula.
The project will also support economic growth and improve livability by making travel safe and reliable to key destinations, including Kangaroo Island.
This project is expected to support approximately 125 full time equivalent jobs per year over the construction period.
Local MP Leon Bignell said “Along with other locals in our area who drive that stretch of road on a regular basis, I’m delighted this funding has been made available to make our roads safer.
“For almost a decade now I’ve been working on getting extra funding for Main South Road and we have seen the duplication from Seaford to Sellicks, the go-ahead for the three overtaking lanes between Normanville and Cape Jervis and now this huge upgrade of the stretch between Myponga and Yankalilla.”
Tom Koutsantonis MP, Minister for Infrastructure and Transport, said “Locals have long called for safety improvements along Main South Road between Myponga and Yankalilla, and now we are getting on with delivering them, together with the Australian government, with this new $80 million initiative.
“The Fleurieu Peninsula is a popular part of our state, and we want to ensure South Australians reach their destination safely.”
