Nearly 5km of utility service relocations have been completed in preparation for the North-South Corridor – Torrens to Darlington (T2D) project in Adelaide, South Australia.

These works allow existing utility services on South Road to be decommissioned, clearing the way for the start of construction of the T2D project.

More than 700 metres of APA Group gas services have been installed, as well as more than 600 metres of SA Water services, more than 1.2 kilometres of SA Power Networks services and more than 2.3 kilometres of telecommunications services.

“The Australian Government is committed to building safer, more efficient road networks like this project in Adelaide,” says Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King.

“This work will ensure smoother and more efficient journeys for commuters, locals, public transport users and businesses,” says Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King.

In addition to utility service relocation works, ground investigation works have been undertaken at many different sites to gain an understanding of the soil and ground water conditions along the South Road corridor.

The ground investigation works have involved drilling 693 boreholes to date, totalling more than 18 kilometres drilled.

“An incredible amount of preparation works is required to ensure the successful construction of a project of this magnitude,” says SA Infrastructure and Transport, Energy and Mining Minister Tom Koutsantonis.

“Relocation of utility services might not be the most visible part of an infrastructure project, but these works are critically important in creating a safe passage for major construction works to be undertaken,” says SA Infrastructure and Transport, Energy and Mining Minister Tom Koutsantonis.

“More than 18 kilometres have been drilled across many different sites as part of ground investigation works to gain a better understanding of the geotechnical and hydrogeological conditions that will be encountered when the tunnels are excavated,” says SA Infrastructure and Transport, Energy and Mining Minister Tom Koutsantonis.

“The Australian and South Australian governments are partnering to deliver stronger, safer and more efficient roads and it’s important we all work together to support better outcomes for communities,” says Federal Member for Boothby Louise Miller-Frost.

“This is a project the people of Boothby regularly raise with me when I am out and about, as they know that this will help them commute to and from work every day,” says Federal Member for Boothby Louise Miller-Frost.

The data collected from these investigations will help inform the detailed design of the tunnels and lowered motorway.

More than three kilometres of South Road has also been resurfaced between Bennet Avenue, Melrose Park and Glengarry Avenue, Glandore.

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 major T2D works.

These resurfacing works are continuing along South Road, with the section from Rothesay Avenue to Lloyd Street, Saint Marys now underway.

“The resurfacing work on South Road is welcomed by my constituents in Elder, as well as by the many thousands of South Australians who use this important road corridor every day,” says State Member for Elder Nadia Clancy.

“This work will provide a benefit now as well as leaving a legacy that will remain even after the North South Corridor is completed in 2031,” says State Member for Elder Nadia Clancy.

This comes as the Australian Government has significantly increased its investment in the project to match the South Australian Government’s $7.7 billion commitment to complete this project.

Early works are expected to be completed by 2025, at which time the main construction works will start – with tunnel boring machine works for the Southern Tunnels planned to begin in 2026. Project completion is expected in 2031.
