2023 a year of progress for T2D project

Significant progress was made on the North-South Corridor – Torrens to Darlington (T2D) project in 2023, preparing the project for a critically important 2024.

More than 700 boreholes over 18 kilometres have been drilled to date as part of ground investigation works to help inform the detailed design of the tunnels and lowered motorway.

More than five kilometres of utility service relocations have been completed, clearing the way for main construction to start.

Procurement for the main construction works started in January 2023, with two consortia shortlisted to deliver the project and the successful consortia to be announced in the third quarter of 2024.

Construction of the Tonsley East substation – to be built, owned and run by SA Power Networks – started in March 2023 and will be completed in early 2024.

This facility will constitute part of the project’s southern laydown area and will supply electricity to the tunnel boring machines and the two parallel 4.5-kilometre-long Southern Tunnels once they are completed in 2030.

More than three kilometres of South Road in both directions have been resurfaced between Bennet Avenue, Melrose Park and Glengarry Avenue, Glandore, with the section from Rothesay Avenue to Lloyd Street, St Marys to be completed in late January 2024.

Resurfacing works along South Road involve removing the existing pavement and replacing it with new asphalt to ensure long-term safety and integrity of these sections ahead of the start of main construction works.

The first two of five interim noise walls along an 850-metre section of York Avenue, Clovelly Park have been installed, with the remaining three walls to be installed by the end of 2024.

More interim noise walls will be installed in other areas along the project alignment to help minimise any potential noise impacts for local residents and businesses.

The pedestrian crossing outside Black Forest Primary School has been upgraded, providing greater protection for pedestrians, including school children, waiting to cross the road.

Concrete barriers and steel crash cushions have been installed to replace the old pedestrian fence, while the pedestrian ramp has also been upgraded.

Works will begin in 2024 to relocate Warriappendi School to bigger and better premises and the Torrensville Bowling Club to a new standalone home.

The project also opened a new dedicated central Community Information Centre at 290 South Road, Hilton, which can host large information sessions and one-on-one meetings for interested stakeholders, with a range of interactive tools to help people further understand the project.

“The Australian Government is committed to building safer, more efficient roads networks by investing in major infrastructure projects like the T2D.

“That’s why in the final quarter of 2023, the Australian Government confirmed the remaining $2.7 billion funding commitment for our contribution of 50 per cent of the project’s $15.4 billion budget.”

Attributable to South Australian Minister for Infrastructure and Transport Tom Koutsantonis:

“The T2D project in Adelaide is the largest and most complex infrastructure project in South Australia’s history.

“This has been massive year for the project, bringing us closer to the start of main construction works.

“We are very confident the design we have developed will deliver great outcomes for motorists and local communities, such as improved travel times, improved safety, improved connectivity and network resilience, and enhanced liveability and opportunities for urban renewal.

“Community consultation is critical to the T2D Project and we thank all residents and business owners for their feedback in 2023 - and we look forward to continuing to engage with the community in 2024.

Attributable to Federal Member for Boothby Louise Miller-Frost:

“More than 6,000 face-to-face interactions, 95 stakeholder meetings and 31 community information sessions were held this year to gain community feedback on several areas of the project, including project design, local area traffic management and the Urban Design Strategy.

“I encourage community members to drop in to the Community Information Centre at 290 South Road, Hilton to learn more about the project and provide further feedback.”

Attributable to State Member for Badcoe Jayne Stinson:

“I want to sincerely thank local residents for their patience and constructive feedback this year.

“It’s not easy for those people who are in the midst of this major project and will be affected for years to come.

"Residents in my area have contributed their local knowledge and insightful feedback on the design, which is leading to better outcomes for everyone.”

Attributable to State Member for Elder Nadia Clancy:

“I’ve received a lot of positive feedback from the community on the resurfacing of South Road that has already occurred, and am really looking forward to that work continuing in St Marys to ensure a smoother, safer surface.”
