About the project

The Australian and South Australian Governments have jointly (50:50) committed $35 million to upgrade the Glen Osmond Road and Fullarton Road intersection. The project is expected to support approximately 50 jobs per year, averaged over the life of the construction period.

The Australian Government’s commitment is part of the Commonwealth Urban Congestion Fund. The South Australian Government’s commitment was announced as part of the 2019-2020 State Budget, to bust congestion by upgrading a number of Metropolitan intersections.

Once complete, the upgrade will improve travel times and road safety, increase intersection capacity and enhance network reliability.

      Campbell Road Traffic Treatment Consultation

      Thank you to all members of the community who took the time to provide feedback across each stage of the consultation process.

      Following presentation to the City of Unley, the Department will review the traffic calming treatments again in mid-2024. This will allow time for the new traffic conditions to normalise, ensuring our traffic monitoring is reflective of how people drive through the area following completion of the intersection upgrade.

      We look forward to sharing more information then.
