Council is a key stakeholder to these projects and has allocated staff to liaise with DIT in relation to impacted Council assets and services to the community.
DIT are upgrading the dual lane roundabout at the Adelaide Road, Wellington Road, Flaxley Road and Alexandrina Road intersection in Mount Barker.
This upgrade will support nearby residential developments in 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 because of development throughout the Mount Barker Urban Growth Area, particularly during peak periods. This upgrade will cater for the increase in traffic and ensure safe and efficient access for all road users.
Works started in 2025 and are expected to be completed late 2026.
