Main South Road Duplication
The State Government has announced a six-day pause to construction activity as part of the COVID-19 response.
The Main South Road Duplication Project will be closed from midnight Wednesday, 18 November until further notice. During this time no works will be undertaken. Reduced speed limits may remain in place due to changed road conditions even though workers will not be on site.
If you need to contact the Main South Road Duplication Project please call 1300 794 880 or email email@example.com
About the project
The State Government funded duplication of Main South Road between Seaford and Sellicks Beach aims to improve road safety as well as improve traffic flow and increase capacity.
The State Government will invest $305 million for Stage 1 which 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.
The 2018-19 State Budget included $2 million in 2018-19 of a total project cost of $305 million for the duplication project to progress planning and procurement for the project.
DIT COVID-19 Response
The Department will continue to tailor community engagement opportunities in line with the latest COVID-19 advice from health authorities.
Face-to-face engagement opportunities may be restricted and we will continue to be guided by the advice of health authorities, with the health and safety of our stakeholders always our highest priority.
Engagement with community and industry is crucial and we will facilitate information sessions as much as possible to enable face to face engagement. It is important to assist in managing these events that you register as requested to enable physical distancing as much as possible.
Why is this happening?
Main South Road now has an average traffic count of 18,000 vehicles per day with these volumes expected to grow with several future housing, commercial and education developments in the area, including a future Super School at Aldinga.
In years 2012-2016, 237 crashes have occurred between, and including, Robinson Road and Sellicks Beach Road, of which 98 were casualty crashes. This equates to 19.6 casualty crashes per year. There have been two fatal crashes.
Main South Road runs from Old Noarlunga to Cape Jervis and is one of the main traffic corridors to the Fleurieu Peninsula.
It is predominantly a two- lane, two-way road traversing rural and semi-urban environments, providing access to southern coastal communities and Kangaroo Island.
This road carries significant traffic between Adelaide and the tourist centres to the south and is a major commuter route for the rapidly expanding residential area of Aldinga.
An increase in traffic volume presents an increasing road safety risk and longer delays for motorists, and safety for motorists and cyclists will be improved by duplicating Main South Road. The duplication will make travelling to, from and within Adelaide’s south safer and easier.
The duplication will assist tourism growth in the southern region by making the Fleurieu Peninsula and its wine regions, walking trails, restaurants and southern beaches more accessible, providing for more economic development opportunities.
A planning study has now commenced for Stages 1 and 2, which will further identify issues and opportunities along the corridor, determine possible solutions that address the issues and opportunities, and develop a concept design from the recommended solution.
Direct engagement with the community will be a strong focus through the planning and delivery for this project.
Planning for Stages 1 and 2 will be complete in mid 2020 at which time the concept design for Stage 1 will be released
What will it cost
$305 million has been allocated for Stage 1 of the project. This includes $2M for a planning study for Stages 1 and 2.
