Main South Road Duplication
The state government has allocated $305 million to Stage 1 of the Main South Road duplication project, from Seaford to Aldinga, improving transport links along one of the main site boundaries.
State Gov project: Stage 1 TBC
Detailed designs are currently being developed, with Stage 1 still waiting to commence. The duplication of Main South Road between Seaford and Sellicks Beach aims to improve road safety, as well as improve traffic flow and increase capacity.
Main South Road has an average traffic of 17,000 vehicles per day, and the duplication will make travelling to, from and within Adelaide’s south safer and easier.
The duplication will be delivered in two stages:
- Stage 1 will involve the duplication of approximately 10 kilometres of Main South Road from south of Griffiths Drive in Seaford to Aldinga. This will include the duplication of the Pedler Creek Bridge at Seaford Rise. This stretch of Main South Road was identified as a priority in the State Government’s Integrated Transport and Land Use Plan. The state Government will invest $305 million for stage 1 of the duplication, supporting 165 jobs a year during construction.
- Stage 2 will continue duplication of Main South Road for approximately 6 kilometres from Aldinga to Sellicks Beach. A previously-announced project to improve safety between Old Coach Road and Malpas Road will still go ahead as planned. The duplication of Main South Road in this section will integrate with these works.
