New map reveals South Road tunnel’s impact on Clovelly Park properties

The path of the final North-South link has been revealed, as has the staggering amount of materials involved. More than 60 homes and businesses will be demolished.

The final stage of the North South Corridor project will feature twice the amount of steel used to create the Sydney Harbour Bridge and more than twice the concrete used in the world’s tallest building, the Burj Khalifa in Dubai.

The state government has laid bare the sheer enormity of the project by revealing how much material will be going into the largest infrastructure project in the state’s history.

It comes as a new map is released showing more details about the first round of property acquisitions and what will be put in their place.

The government will on Wednesday outline for the first time exactly what it will require to deliver the $9.9 billion last stage of the North South Corridor at the 2021 Annual Construction Sector Industry Briefing.

The Advertiser can confirm the project will use 470,000 tonnes of asphalt; 760,000 cubic metres of concrete; 2 million tonnes of quarry products; 100,000 tonnes of steel; and 470,000 litres of bitumen.

It will also produce 8 million tonnes of spoil.

Infrastructure Minister Corey Wingard said the final stage would use a total of more than 3.5 million tonnes of material.

“To put the size of this project into perspective, the amount of steel needed is the equivalent of two Sydney Harbour Bridges,” he said.

“The amount of material that’s going to be needed is staggering and where practical we’ll try to source it locally which provides a great opportunity for SA businesses.”

Mr Wingard said the briefing would “give local firms the time to scale up their operations to be in the best place possible to be part of this huge project”.

Federal Urban Infrastructure Minister Paul Fletcher said when considering the volume of materials required to complete the final stage of the project – just 10.5km of the entire 78km corridor – “the scale of the broader project is all the more compelling”.

Meanwhile, the government has released a new map that shows further details about the first round of property acquisitions, in Clovelly Park, which will result in more than 60 homes and businesses being demolished.

Those affected have been notified by the Transport Department.

The map shows which properties will be demolished and what will be taking their place.

Among the new details, the map shows where cranes, grout and bentonite plants, a workshop area, a shower block, storeroom and gatehouse and traffic control facilities will be located.

Climbing and fitness gym Beyond Bouldering opened a new $1.3 million facility in Clovelly Park in July but soon discovered the business’s building was set for the wrecking ball.

Beyond Bouldering Clovelly Park manager Alice Dixon said the gym had been told it had until late November 2022 to vacate the building.

“The gym itself is stunning and so much money has gone into it – It was really tough news,” she said.

Ms Dixon said the hunt was now on to find a new premises for the gym.

The Advertiser reported on Saturday that work is underway to relocate electricity and phone services in Clovelly Park as part of the project.

Under an $85 million package of “early works,” SA Power Networks cabling and Optus telecommunications services are being moved to clear the way for the project’s southern tunnel, launch site and staging area.

Major construction of the project is expected to start in late 2023.

The final section of the North-South Corridor will be rolled out in two stages.

Stage one involves the construction of a motorway from Darlington to Anzac Highway, including a 4km tunnel.

The second stage will involve motorways from the Gallipoli Underpass to Sir Donald Bradman Drive and from West Thebarton Rd to the Torrens to Torrens section of the project.

A 4km tunnel is also included in the stage.

Once completed, the upgrade will create a 78km non-stop motorway from Gawler to Old Noarlunga, allowing drivers to bypass 21 sets of traffic lights and saving 24 minutes in travel time.
