Congestion relief on the way for key South Road connection
Monday 4 August 2025
Construction of a new link road that will remove a notorious ‘dogleg’ at a much-used South Road intersection will get underway in coming weeks, with contractors selected to deliver the Raglan Avenue, Edward Street and South Road network upgrade.
Construction company BMD has been awarded the contract for the project which includes the construction of a new link road that will remove the ‘dogleg’ movement for traffic travelling between Edward Street and Raglan Avenue.
The intersection of South Road and Price Street will be also upgraded to include the installation of traffic signals, a pedestrian crossing and a dedicated right turn lane into Castle Plaza.
The project forms part of the $850 million Broader Network Upgrade package of works as part of the River Torrens to Darlington Project to create a non-stop South Road.
These suite of enhancements to intersections near the T2D Project will collectively ensure the Adelaide road network functions efficiently, both during construction of the Project and once it is completed.
Following community feedback and additional technical planning on the proposed design for the Raglan Avenue, Edward Street and South Road network upgrade, further enhancements have been made including:
- Signalised dedicated right turn lane onto South Road from Edward Street.
- extending the dedicated left turn lane onto South Road along the new link road.
- indenting bus stops along the new link road.
- the inclusion of a wombat crossing on Raglan Avenue east of the new roundabout to improve pedestrian safety.
- landscaping within the project area.
The Raglan Avenue, Edward Street and South Road network upgrade is due to be completed in late 2026.
The T2D Project is the final 10.5km section of the North-South Corridor, and will complete 78km of non-stop, traffic light free motorway between Gawler and Old Noarlunga.
