The 400m ramp will take north-bound motorists from the tunnels and directly onto Anzac Highway towards the city over the top of the Anzac Highway-South Road intersection.
The State Government says no compulsory acquisitions will be required for this part of the project, although noted some unspecified “vegetation impacts”.
Transport Minister Corey Wingard this morning said the State Government was faced with a choice between acquiring homes and removing trees.
“There are a couple of options and it was either acquire homes along Anzac Highway or impact the trees,” he told ABC Radio this morning.
“We figured that impacting the trees was less impactful and there was the opportunity to relocate some of the trees.
“We think we’ve got a great opportunity to have some really nice uplift in that area, and the trees were preferable over the homes.”
Wingard said there would be 20 per cent extra tree canopy once replantation around the site is completed.
It comes after the State Government announced in September that 110 homes would have to be acquired in Glandore, where the tunnels surface just ahead of the Glenelg tram overpass.
A further 64 properties will be compulsory acquired further south around Clovelly Park for the “southern laydown area” where the launch site for the tunnels will be located.
Wingard said the next part of the design the Department of Infrastructure and Transport is working on is the second tunnel link between the South-Road Anzac Highway section and Sir Donald Bradman Drive further north.
The second tunnels will surface around Thebarton Oval, according to Wingard, with any associated property acquisitions to be detailed along with the full release of the project’s reference design – expected before the end of the year.
Other details revealed over the weekend include a pedestrian overpass for people accessing Black Forest Primary School and Black Forest Shopping Centre around where the tunnels surface.
The entire 10.5km, $9.9 billion project is slated for completion by 2030.
Construction on the southern tunnels will begin in late 2023.
