Suite of key road projects to boost revamped motorway

Friday, 16 December 2022

Thirteen crucial infrastructure upgrades, together valued at $850 million, will be carried out across Adelaide to support and complement the revitalised River Torrens to Darlington (T2D) Project.

The works are forecast to support 300 jobs a year during construction, and are essential to the proper functioning of the motorway and wider road network both during and after construction of the project.

The pipeline of initiatives is similar in budget to some of the recently completed projects on the North-South Corridor – such as the Darlington Upgrade Project, Torrens to Torrens Project and Northern Connector Project – and represents a significant opportunity for South Australian workers and businesses.

On 14 December, the State Government announced that, following a comprehensive review, the 10.5km T2D Project will incorporate major design changes, including the removal of large elevated roadways and the addition of new entry and exit ramps to improve safety, connectivity and visual amenity for local communities.

Once finished, the T2D Project will complete 78km of non-stop motorway between Gawler and Old Noarlunga, and allow motorists to avoid 21 existing sets of traffic lights between the River Torrens and Darlington.

The first of the 13 supporting projects to be undertaken – the building of a new road linking Selgar Avenue, Clovelly Park, to the all-important Tonsley precinct – is situated in the heart of the T2D Project’s initial work area and is expected to start in the first quarter of 2023.

Other essential network and amenity upgrades include:

  • Richmond Road – widening Richmond Road between South Road and Railway Terrace, including an upgrade of the Railway Terrace intersection;
  • James Congdon Drive – introducing two right-turn lanes from James Congdon Drive citybound onto Sir Donald Bradman Drive;
  • Tram overpass – modifying the Glenelg tram overpass at South Road by increasing spans, constructing new footings and creating usable community space underneath;
  • Edward Street and Ackland Street intersection – creating a direct link to Raglan Avenue to remove a notorious “dog leg”, unlock development opportunities and ease congestion, including the provision of a signalised right-turn phase from Edward Street onto South Road; and
  • Manton Street/Adam Street junction – adding an additional left-turn eastbound lane from Manton Street onto Adam Street into the CBD.
