World leading experts to support North-South Corridor design

The Marshall Liberal Government will receive expert, industry-leading advice to finalise the business case and development of the reference design for the final stage of the North-South Corridor from SA based Joint-Venture Aurecon Mott MacDonald.

Aurecon Mott MacDonald JV has been awarded the Master Advisory Services contract, having worked on some of the most complex transport projects in Australia.

Minister for Infrastructure and Transport, Corey Wingard, said the Master Advisory Services is essential for a project of this scale to ensure accurate and independent technical advice is received to inform the design and planning.

“The Torrens to Darlington (T2D) section is one of the most important projects ever delivered for our state and will create up to 4,000 jobs,” Minister Wingard said.

“The tunnelling solution we’ve come up with will minimise community impact, improve east-west connectivity, increase overall network capacity to reduce congestion, and deliver greater safety benefits.

“With the hybrid+ solution we can protect iconic community and heritage assets including the Thebarton Theatre, Hindmarsh Cemetery, Hoffman Brick Kiln and Queen of Angels Church, to name a few.”

“The hybrid+ solution also means hundreds fewer homes and businesses will be impacted with modelling suggesting around 390 properties will need to be acquired. In comparison, the open-motorway option would have required close to 900 homes and businesses to be demolished.

“The final 10.5 kilometres is the most difficult part of this continuous motorway, and we already have $5.4 billion on the table towards its completion.

“This is why it is absolutely essential we have the best advice possible as we progress through the different elements of the project.

“Aurecon Mott MacDonald JV have extensive experience in projects of similar size and complexity, including the North-East Link, WestConnex, Torrens to Darlington and other major road projects in South Australia.

“Their advice and learnings will be hugely important to help inform the final design of the Torrens to Darlington upgrade.

“This specialist advice will support the Department for Infrastructure and Transport by providing:

  • Land, planning and environment advice to seek appropriate approvals for the project.
  • Engineering and technical advice in the development of the final business case and reference design.
  • Input into the preparation of the tender requirements for the Delivery contract procurement process.

The contract has been awarded for an initial 12 months, with options to extend if required.

The completion of the T2D project will deliver a 78-kilometre non-stop, free-flowing motorway that seamlessly links Gawler, to the north of the city, with Old Noarlunga in the south.
