Government invests to upgrade Main South Road, Aldinga

13 January 2016

Main South Road between Old Coach and Malpas Roads, Aldinga will benefit from an $11.2 million investment for road safety improvements.

The upgrade forms part of the Motor Accident Commission’s $100 million investment in road safety infrastructure.

Between 2005 and 2014, there have been 50 casualty crashes on this stretch of road resulting in three fatalities, 11 serious injuries and 68 minor injuries. 78 per cent of these crashes occurred at intersections.

As part of the investment, a new, large single lane roundabout will be built at the junction of Port Road and Main South Road, Aldinga.

The announcement of the upgrade follows community consultation on the Main South Road Road Management Plan.

Stakeholders, residents associations and the local community were consulted on the plan, which recommended a series of improvements between Tatachilla Road and Sellicks Beach Road.

1.5 kilometres of median wire rope will be installed between Port Road and Malpas Road as well as a u-turn facility near Malpas Road.

Motor Accident Commission Chief Executive Officer, Aaron Chia said investing in road safety along Main South Road would improve road conditions and safety outcomes for motorists.

"Main South Road is a major freight and transport route and the upgrade will result in safer journeys for all road users," Mr Chia said.

Main South Road carries about 14,000 vehicles a day and provides a key link between Adelaide and the suburbs and tourist centres to the south.

The road is the major commuter route for the expanding residential areas of Aldinga and Sellicks Beach, and many residents have raised the need to improve the safety of the road as the population increases.

This first project from the Road Management Plan will tackle one of the most dangerous and busy intersections in the South with further Main South Road improvement projects to be delivered over time.

Other safety improvements as part of the upgrade will include:

  • Road widening and resurfacing, improved lighting, road signage and line marking;
  • Speed limit reduction from 100 km/h to 90 km/h, between Seaford Heights and Aldinga
  • Speed Limit reduction from 80 km/h to 70 km/h, between Little Road and Hart Road.

Works are expected to commence this year and be completed in 2017.
