Darlington upgrade project

Laing O'Rourke will join forces with Fulton Hogan to deliver South Australia's $620m Darlington Upgrade Project, a 3.3 kilometre road link to benefit commuters, business and the SA economy.

Laing O'Rourke will join forces with Fulton Hogan to deliver South Australia's $620m Darlington Upgrade Project, a 3.3 kilometre road link to benefit commuters, business and the SA economy.

As the Gateway South consortium, the two infrastructure companies have been announced as preferred bidder for the project, jointly funded by the Commonwealth and South Australian Governments.

Announcing the successful tender, Federal Minister for Major Projects, Territories and Local Government Paul Fletcher said the North-South Corridor is one of Adelaide’s most important transport corridors.

“The Darlington project will reduce congestion, improve safety, boost freight transport productivity and increase competitiveness for export industries,” he said.

“Travel time savings are also expected to be significant for motorists and public transport users.”

The project features:  

  • A non-stop motorway between the Southern Expressway and Tonsley Boulevard

  • A lowered, non-stop motorway passing underneath Flinders Drive, Sturt Road, Sutton Road/Mimosa Terrace and Tonsley Boulevard

  • Grade separation of the Main South Road/Ayliffes Road/Shepherds Hill Road intersection

  • Main South Road (at grade) service roads along both sides of the lowered motorway to provide connections to Flinders Drive, Sturt Road and most local roads

  • Full free flow interchange at the Southern Expressway/Main South Road with dedicated ramps providing direct access to the new motorway and Main South Road

  • An upgrade to the Marion Road/Sturt Road intersection to cater for the redistribution of traffic during the construction period.

South Australian Transport and Infrastructure Minister Stephen Mullighan said construction on the Darlington project is expected to commence in early 2016, and to be completed by the end of 2018.

Laing O’Rourke Region Director Pat Cashin welcomed the announcement and the collaboration with Fulton Hogan and the State and Federal Government agencies.

“As Australia’s largest privately-owned engineering and construction company, Laing O’Rourke is committed to bringing both local capability and our national major infrastructure experience to this exciting project for Adelaide and South Australia.”
