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.

Local benefits

Benefits to the local community include:

  • smoother and safer journeys
  • improved safety for all road users
  • better access for cyclists and pedestrians
  • improved response for emergency services
  • preserving the character of the Adelaide Hills
  • boosting South Australia’s economy, supporting 260 jobs per annum over the construction period.
