Non-stop travel through Adelaide

The final part of Adelaide’s most important transport route – the North-South Corridor – is in development phase, with full funding for the 10.5km Torrens to Darlington (T2D) project confirmed in February this year.

Main construction on the $9.9 billion project is expected to start in late 2023 and be finished by 2030.

The T2D Project will complete 78km of non-stop travel on the North-South Corridor between Gawler and Old Noarlunga, and allow motorists to bypass 21 sets of traffic lights between Darlington and the River Torrens.

“As the most significant road infrastructure project ever undertaken in South Australia, the T2D Project will unlock Adelaide’s traffic network, stimulate economic growth while sustaining liveability, and deliver long-term benefits for South Australians,” ICN Consultant Eddie Ivar said.

ICN SA has been working with the Department for Infrastructure and Transport (DIT) and its head contractors through various stages of the North-South Corridor Development, including the Northern Expressway, South Road Superway, Torrens to Torrens Upgrade, Darlington Upgrade and Northern Connector projects.

‘Through the delivery of these projects, the Government and the lead contractors have been committed to engaging local suppliers and supporting local jobs as part of their industry and workforce participation plans,’ Eddie said.

The T2D Project is the vital missing link in the North-South Corridor and will deliver three motorway lanes in each direction, with a combination of tunnels, lowered and surface-level motorway, as well as underpasses and overpasses at key intersections. It will connect the Darlington Upgrade in the south to the Torrens to Torrens Upgrade in the north.

The motorway will will include four key sections in a staged delivery:

  • The Southern Tunnels will integrate with the Darlington Upgrade and connect Darlington to Anzac Highway. This section will deliver approximately 6 km of motorway, including more than 4.8 km of twin three-lane tunnels, and a new city-bound elevated ramp connecting the T2D with Anzac Highway.
  • The Southern and Northern Tunnels connect via an at-surface tunnel connector, which will link with surrounding arterial roads, such as Anzac Highway and Richmond Road
  • The Northern Tunnels, between Sir Donald Bradman Drive and Torrensville, will provide a further 2.2 km of twin three-lane tunnels.
  • The Northern Tunnels will integrate with the Torrens to Torrens Upgrade through the Torrens connector, crossing over the River Torrens with an elevated section of northbound road.

While DIT is refining the delivery strategy for procurement of the project, it is using ICN Gateway to invite initial expressions of interest across a range of work packages. Details of registered suppliers will be provided to the successful tenderers for the major construction package contracts.

“It is a great example of the benefit of getting involved at the tender stage of these major projects. Local suppliers have the opportunity to engage in the project earlier, while the organisations bidding for first-tier contracts can gain a better understanding of available capabilities, capacity and innovations for their supply chain,” Eddie said.
