About the project

The Northern Connector road project , is a critical component of Adelaide’s North-South Corridor that will link major transport routes and enable an unimpeded journey from Port Wakefield, the mid north, the Barossa Valley and the Riverland to the Port of Adelaide or the length of the corridor, to Old Noarlunga.

The 15.5 kilometre non-stop motorway, to the west of Port Wakefield Road, will extend from the Northern Expressway interchange with Port Wakefield Road at Waterloo Corner, to the Port River Expressway and the South Road Superway interchange at Wingfield.

Linking with the Northern Expressway and the South Road Superway, with three lanes in each direction, a posted speed limit of 110 kmph and four road interchanges, this motorway will serve as a new national road link to provide better connection between Adelaide, the Port of Adelaide and the northern suburbs and beyond (including the Mid North, Barossa Valley and Riverland).

The project will also provide a 16 kilometre path for cyclists and pedestrians that will connect with the Northern Expressway’s existing 23 kilometre path.

The Northern Connector will cater for the forecasted traffic volumes from the north, currently reliant on Port Wakefield Road. In the long term, this project will also remove freight trains from suburban lines and level crossings, improving travel times for both freight and suburban rail operations.

Planning work commenced on the Northern Connector in 2008 and since then, the Department has explored numerous options, shared information with people living and working along the proposed corridor, local government, state agencies and representative bodies.

In July 2011, a Project Impact Report for the Northern Connector was publically released for consultation. In total, 28 submissions were received and have helped inform further planning activities and the development of the funded scheme.

The current scheme is still subject to change as further community engagement and design progresses.
