South Eastern Freeway Interchanges Upgrades
The Australian and South Australian governments have committed $150 million (80:20) to upgrade the Mount Barker and Verdun interchanges.
We aim to improve:
- connectivity to the South Eastern Freeway
- the capacity of the interchanges in response to existing and projected growth for Mount Barker and the Adelaide Hills area.
Major construction is planned to start in late 2025.
