The Marshall Government will commission a planning study for the $305 million Main South Road Duplication project.
The State Government has committed to deliver Stage 1 of the project which will involve the duplication of approximately 10 kilometres of Main South Road from south of Griffiths Drive in Seaford to Aldinga.
Stage 2 would continue the duplication of Main South Road for approximately 6 kilometres from Aldinga to Sellicks Beach.
“The duplication of Main South Road is an important project that will improve road safety and ease traffic congestion,” said Minister for Transport, Infrastructure and Local Government, Stephan Knoll.
“This is a significant infrastructure investment and forms part of to the Marshall Government’s record $11.3 billion pipeline of infrastructure works over the next four years.
“The planning study will, in consultation with key stakeholders and the community, identify issues, undertake investigations and determine a preferred concept for both Stage 1 and Stage 2 of the duplication.
“We have seen significant growth in the southern suburbs and associated increase in traffic volumes along Main South Road by approximately 6 per cent per year between 2001-2017.
“Traffic volumes are expected to grow with several future housing, commercial and education developments in the area.
“The project will improve road safety and accommodate the growing residential areas of Aldinga Beach, Sellicks Beach and Port Willunga.”
Main South Road is predominantly a single carriageway, two-way arterial road which runs from Old Noarlunga to Cape Jervis and is one of the main traffic corridors to the Fleurieu Peninsula.
The planning study will be conducted via a select tender process.
