Feedback currently being sought.
Concept design Stage 2 will commence this year.

Concept designs have been developed for Stage 1 of the Main South Road Duplication Project, between Seaford and Aldinga and for the Victor Harbor Road Duplication Project, between Main South Road and Main Road, McLaren Vale

The concept designs for both projects have been developed to encompass project objectives, design criteria, community and stakeholder feedback to date and the outcomes of environmental, social, safety, economic and preliminary site investigations.
