Adelaide Road, Mount Barker Roundabout Upgrade
The South Australian Government has committed $40 million as part of the 2023-2024 State Budget to upgrade the roundabout located at the intersection of Adelaide Road, Alexandrina Road, Wellington Road, and Flaxley Road in Mount Barker. This has been identified as a priority upgrade within the Mount Barker Infrastructure Deed, which will support nearby residential developments occurring within the Mount Barker Urban Growth Area and the broader Mount Barker area.
Traffic volumes on these roads and the associated delays are expected to increase significantly as a result of development occurring throughout the Mount Barker Urban Growth Area, particularly during the peak periods.
The upgrade will include the provision of additional lanes, shared use paths and road lighting improvements. The project will cater for the increase in traffic, and ensure safe and efficient access for all road users.

We have developed a concept design to improve safety for all road users and deliver enhanced traffic capacity to cater for this increased demand and complement other infrastructure upgrades being undertaken in the area.
Adelaide Road, Mount Barker Roundabout Upgrade concept design
The project will include a new, dual lane roundabout at the intersection of Adelaide Road, Alexandrina Road, Wellington Road and Flaxley Road.
Adelaide Road and Flaxley Road will receive new signalised pedestrian crossings, while the existing crossing on Wellington Road will be relocated to improve safety. The roundabout will also include new Shared Use Paths and road lighting.
The preferred concept design will improve intersection performance and connectivity to support growth in the area, including the recently announced expansion of the Mount Barker Hospital.
We have developed a What We Heard report from your feedback at our Community Listening Posts and our online survey in October and November 2023.
Community engagement
Insights from the local community and key stakeholders along with technical assessments have played a key role in informing the concept design for the upgrade at the intersection of Adelaide Road, Alexandrina Road, Wellington Road, and Flaxley Road in Mount Barker.
We are committed to working with the local schools and community to ensure the upgrade works are delivered smoothly and we continue to minimise any potential impacts.
