Additional Investment Announced For $250M Curtis Road Project

The South Australian Government will match the Federal Government’s $125 million investment to remove the Curtis Road level crossing in Munno Para, a key connection in Adelaide’s growing northern suburbs.

The funding will be formally announced as part of the 2025/26 South Australian State Budget, which will be released next Thursday (June 5, 2025).

The northern suburbs of Adelaide – which includes areas such as Munno Para, Angle Vale, Riverlea, Kudla, Concordia, and Roseworthy – are predicted to see significant population and economic growth over the next 30 years and beyond. It’s the fastest growing region in the state.

The State Government recently undertook the Northern Adelaide Transport Study, which identified Curtis Road as an important east west link and access route to the North South Corridor. Currently, the Gawler Railway line crosses Curtis Road, 500 metres west of Main North Road.

Approximately 21,000 vehicles pass through this level crossing each day, and during peak periods the boom gates can be down for up to 15 minutes every hour. The removal of the rail level crossing and grade separation will improve safety and travel time reliability by reducing road and rail network conflicts.

A planning study for the works will soon commence, with a concept design to be released in 2026. Major works will commence by 2027, with an expected completion in 2030.

The 2025/26 State Budget for South Australia will also include $80 million in joint funding from the State and Federal governments (50:50) over five years for safety improvements on a section of Main South Road between Myponga and Yankalilla.

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.

Together, this now brings a total investment of $111.8 million to deliver five overtaking lanes and other safety upgrades on Main South Road between Myponga and Cape Jervis.

Premier Peter Malinauskas said these works would help to increase the safety and efficiency of connections heavily relied upon by motorists.

“The northern regions of Adelaide are projected to be our fastest growing in the next 30 years, accounting for 40 per cent of Greater Adelaide’s projected population growth,” he said.

“Significant growth like this needs investment in infrastructure, particularly for important links like Curtis Road, which provides a vital connection between east and west and towards the North-South Corridor.”
