Also referred to as the Southern Tunnel, Stage One of the Torrens to Darlington project will include northern entry and exit points and a direct connection to Anzac Highway. Stage One includes 6 km of motorway, of which over 4 km is to comprise twin three-lane tunnels.
Besides the tunnels, the section includes an elevated ramp at Glandore providing a crucial connection onto Anzac Highway that allows motorists to drive direct from the southern suburbs onto Anzac Highway towards the Adelaide CBD without stopping at traffic lights.
Federal Minister of Communications, Urban Infrastructure, Cities and the Arts Paul Fletcher said the announcement on the Anzac Highway connection marked another key milestone in the delivery of the T2D Project.
“The T2D is the final piece of one of the most significant projects in the state’s history and will not only dramatically reduce travel times for people going north and south but will also make it much quicker and safer for the thousands of motorists travelling into the city,” he said.
“By alleviating congestion across the city, we’re helping people to get home to their families sooner and safer, we’re helping freight move more quickly between our cities, and we’re generating thousands of jobs for South Australians.”
The solution for this vital east/west traffic movement was identified following a rigorous planning and design process and will be achieved without any property acquisitions on Anzac Highway.
Early designs for the connection between the T2D motorway and Anzac Highway had further acquisition impacts, including local heritage-listed buildings.
The T2D motorway was designed to solve congestion issues and cater for predicted future traffic growth, improve north to south movement on the road network and improve connectivity across the corridor and into the CBD.
Construction of the Southern Tunnels is expected to start in late 2023, with the entire 10.5km project to be completed – subject to planning, approvals and funding – in 2030.
