Southern Expressway open to two-way traffic

The Southern Expressway opened to two-way traffic on Sunday 3 August 2014.

Please click here to download a copy of our latest brochure, providing information on how to use the duplicated expressway. Please observe and obey on-site signage and take care whilst driving along the expressway and through the interchanges.


Works after opening to two-way traffic

Some construction activities will continue including interchange ramp road works, activation of the new two-way electronic signage system, landscaping, fencing, construction of the new western recreational pathway and noise barrier installation.

For further details on these works please visit the traffic restrictions page.


Nightworks at Main South Road/Southern Expressway/Panalatinga Road Intersection

Nightworks will be underway at the intersection of Main South Road, Panalatinga Road and the Southern Expressway ramp (Reynella) from Monday, 11 August until Friday, 22 August between 7.00 pm and 6.00 am.
 
The works will involve road surface removal and final resurfacing through the intersection.

Road closures and detours will be in place around the intersection. These restrictions and detours will change as required during the works so motorists are asked to pay careful attention to on-site signage. In general, the following will be restricted at varying times throughout the works:

  • Travel between Panalatinga Road and Main South Road – traffic will be detoured via Chandlers Hill Road
  • Old South Road traffic will be detoured onto Reynell Road
  • Panalatinga Road and Kenihans Road traffic will be detoured via Chandlers Hill Road
  • Access to and from the expressway to Panalatinga Road

Pedestrian access will be maintained throughout the works with detours in place as required.

Bus services will be maintained throughout the works with bus stop 40 temporarily relocated onto Main South Road during the works and local shuttle buses in operation when required between stops 41 – 44 on Old South Road . Please observe on-site signage for information.

Advanced warning signs will be used to notify road users of changed traffic conditions.

The $407.5 million duplication of the Southern Expressway is a key part of the development of Adelaide's north-south corridor and, when complete, will deliver an 18.5 kilometre multi-lane, two-way expressway between Bedford Park and Old Noarlunga.

This will provide people living in Adelaide’s south with improved access to employment, education, shopping and community facilities and will put Adelaide’s southern beaches and the McLaren Vale wine region within easier reach.

This project will also support economic activity in Adelaide’s southern commercial and industrial areas like Reynella, Lonsdale and Noarlunga Centre as well as help the state achieve identified targets in the South Australia Strategic Plan.
