Early works prepare T2D for start of construction
Nearly five kilometres of utility service relocations have been completed in preparation for the T2D Project.
These works allow existing utility services on South Road to be decommissioned, clearing the way for the start of main construction works.
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.
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 around 700 boreholes to date, totalling more than 18 kilometres drilled.
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 main construction works.
These resurfacing works are continuing along South Road, with the section from Rothesay Avenue to Lloyd Street, Saint Marys well underway.
This comes as the Australian Government has 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, ahead of main construction works, with tunnel boring machine works for the Southern Tunnels planned to begin in 2026. Project completion is expected in 2031.
