5 September 2017

The Department of Planning, Transport and Infrastructure (DPTI) advises that the contract for road safety improvements along Main South Road between Old Coach Road and Malpas Road, Aldinga was awarded to York Civil Pty Ltd.

The Motor Accident Commission (MAC) allocated $11.2 million for the works that will improve safety for road users along this stretch of road that is used by approximately 17,900 vehicles per day.

The project includes the following safety improvements:

  • A roundabout at the junction of Port Road and Main South Road.
  • A two metre wide traffic median with wire rope safety barrier between Port Road and Malpas Road.
  • Repositioning of the northbound overtaking lane on Main South Road near Malpas Road.
  • Road widening and resurfacing.

The works will improve traffic flow, and aim to reduce the number and severity of serious and minor injury crashes.

Works have commenced on site and are expected to be completed in the second quarter of 2018, weather permitting.

The road remains open to traffic with a 25 km/h speed restriction in place while workers are on site. Lane restrictions are in place along Main South Road, from Malpas Road to Old Coach Road. These restrictions will remain in place for the duration of the project.

Some local detours will be necessary during the works and signage will be in place to advise motorists of the changed traffic conditions.

DPTI thanks road users for their patience while these important safety works are undertaken.

Between 2005 and 2014, there were 50 recorded casualty crashes on this section of Main South Road between Old Coach Road and Malpas Road, resulting in three fatal, five serious injury and 42 minor injury crashes.

Of the 50 recorded crashes, 78 per cent have occurred at four junctions: Malpas Road, Little Road, Port Road and Old Coach Road.

The $11.2 million MAC funding comes after the release of the DPTI Road Management Plan which identified a number of opportunities to improve road safety, following extensive consultation with the community and stakeholders.

These works will be integrated with the duplication of Main South Road between Seaford and Sellicks Beach project.
