Verdun Interchange Upgrade

The existing Verdun Interchange will be upgraded to a full interchange, allowing access to and from the South Eastern Freeway in all directions. Upgrading this interchange will improve connectivity, traffic efficiency and commuter safety in the area.

The Verdun Interchange currently only allows access to/from metropolitan Adelaide, with 11 crashes reported at the interchange between 2019 and 2023.

The Verdun Interchange is expected to be open to traffic in late 2027.

Key features include:

  • a new eastbound entry ramp (towards Mount Barker);
  • a new westbound exit ramp;
  • a new single lane roundabout at the Mount Barker Road/Silver Road junction;
  • existing Bus Stop 48A on both sides of Mount Barker Road to be consolidated with Bus Stop 49; and
  • minor realignment of the freeway to accommodate the new exit ramp.
