Main South Road Overtaking Lanes - Myponga to Cape Jervis

Project Overview

The Australian and South Australian Governments have jointly committed $31.8 million (50:50) to improve safety for all road users on Main South Road, between Myponga and Cape Jervis. As part of the South Australian Government’s election commitment to deliver three new overtaking lanes along this section of Main South Road, we have undertaken extensive planning to inform this work. After analysis of feedback received, as well as technical assessments, we have identified three locations for the overtaking lanes.

These overtaking lanes will support improved traffic flow and safety for locals, tourists, and heavy vehicles, while also building capacity for future growth.

Preferred Overtaking Lane Locations

After analysis of technical information and stakeholder feedback we have identified three preferred locations for the overtaking lanes. These locations are:

• Between Second Valley and Normanville (northbound);
• Between Delamere and Second Valley (southbound); and
• Between Cape Jervis and Delamere (northbound).

We are now working to develop a concept design for the overtaking lanes.

Community Engagement

In 2023 we sought feedback to help us better understand potential locations for the three new overtaking lanes. This engagement process was an early opportunity to hear community insights and understand local experiences that might not be captured by a technical analysis.

More than 190 pieces of feedback were received, including 167 interactive map comments and 16 survey submissions. Thankyou to everyone who took the time to provide feedback during this period.

Of the 94 locations identified as beneficial overtaking lane locations on the interactive map, the top three recommendations were:

• 26 pins: Second Valley Finnis Vale Drive to Wirrina Cove Paradise Drive;
• 17 pins: Cape Jervis: Fishery Beach Road to Sappers Road; and
• 10 pins: Delamere: Yoho Road to Morris Road.

View the What We Heard Report

Information sessions were held on Sunday 29 and Monday 30 September 2024 in Second Valley and Friday 25 October and Saturday 26 October 2024 in Cape Jervis and Myponga to provide an opportunity for the community to meet with representatives of the Project Team and ask any questions about the proposed locations for the overtaking lanes. Useful insights were heard during these sessions and will help inform the final design for the overtaking lanes.

We will continue to engage with the community as we progress the detailed concept design for each overtaking lane.
