Arup, Mott MacDonald win roles on $247m Australian motorway connection

A consortium of two UK consulting engineers, Arup and Mott MacDonald, and local firm McConnell Dowell Constructors, has been selected to carry out a US$247m contract for a 1.8km stretch of the North-South motorway corridor in Adelaide, South Australia.

The project, which links Regency Road to Pym Street, includes:

  • A 1.8km six-lane motorway
  • The creation of two lanes in each direction on the South Road
  • A three-lane overpass over Regency Road with a two-lane surface road underneath
  • A separated pedestrian and cycle overpass over South Road in the vicinity of Pym Street

The development is described by the by the Ministry of Cities, Urban Infrastructure and Population as "the final missing link" of the North-South Corridor between Gawler and the River Torrens.

The project is being jointly funded by the Australian federal and the South Australian state governments.

Alan Tudge, Cities, Urban Infrastructure and Population minister, said: "When complete, it will deliver efficient and reliable travel for up to 53,000 vehicles per day on this section of South Road by removing the need to travel through two signalised intersections."

Construction on the project is due to begin in late 2019 and be completed in 2022. Some 210 full-time jobs are expected to be created over the project’s lifespan.
