The South Australian Government has released new tenders for works on the $9.9 billion Torrens to Darlington Project (T2D) – the final and the most complicated piece of the North-South Corridor.

The T2D Project is the largest road infrastructure project in South Australia’s history and when complete in 2030, it will provide a 78-kilometre non-stop, traffic light-free North-South Corridor between Gawler and Old Noarlunga.

Using a combination of tunnels, lowered and ground-level motorways, as well as overpasses and underpasses at key intersections, T2D will bypass 21 sets of traffic lights between the River Torrens and Darlington.

Stage One (Southern Tunnel) between Anzac Highway and Darlington will including more than four kilometres of tunnel. Stage Two (Airport Link and Northern Tunnel) between the River Torrens and Anzac Highway will include a second tunnel and at-surface motorway.

The T2D Project has already awarded contracts worth more than $100 million, supporting 286 jobs. Construction of Stage 1 of the T2D Project is expected to start in 2023 and take about five years to complete, while work on Stage 2 is scheduled to begin in 2026, subject to planning, approvals and funding, with completion scheduled for 2030.

When complete, around 60 per cent of the T2D Project will be comprised of underground tunnels. The project will support more than 4500 jobs during construction.

Tenders have been issued by the South Australian Government for works on the North-South Corridor Torrens to Darlington section. These include the construction of tunnels, building inspection service, cable laying, bridge construction including construction from prefabricated components and asphalt surfacing.

Potential contractors are now able to register their interest for providing services to the project. The tenders expire 20 December 2022.

The T2D Project is jointly funded by the Australian and South Australian governments.
