The 10.5 km T2D project is the final piece of the multi-billion-dollar 78 km North-South Corridor which will help unlock Adelaide’s transport network by providing a non-stop connection between Gawler and Old Noarlunga, with links to the port and airport precincts.
This week, the SA Government revealed a purpose-built site near Tonsley Boulevard will be used to assemble to tunnel boring machines (TBMs) that will dig 4 km of tunnels for the new 6 km motorway.
SA Minister for Infrastructure and Transport Corey Wingard said with more than 4,500 jobs anticipated for creation, the T2D was the biggest job-creating infrastructure project in the state’s history.
“The project team has commenced engagement with affected property owners in the southern laydown area and negotiations regarding acquisition have begun,” he said.
“Our solution to complete the North-South Corridor saves hundreds of homes and businesses from acquisition.
“The development of the reference design is ongoing and will be finalised in the second half of the year.
“The hybrid+ design means around 60 per cent of the project will be tunnels.
“We’re proud to be delivering a project of this scale and complexity, and proud of the difference it will make for thousands of South Australians each day.”
The project is jointly funded by the Australian and South Australian governments, with $5.4 billion budgeted for the section between Darlington and Anzac Highway.
Construction on this section expected to begin in 2023, with completion planned for 2028.
