VERDUN INTERCHANGE UPGRADE – NEW ROUNDABOUT OPENING IN STAGES
The Department for Infrastructure and Transport (DIT) is progressing its upgrade of the Verdun Interchange, which will eventually allow motorists to enter and exit the South Eastern Freeway in both directions.
As part of the project, the new roundabout at the intersection of Mount Barker Road and Silver Road will open in stages, with the following works and traffic changes planned:
🚧 Early November to mid-December: Pavement works on Mount Barker Road, with speed and lane restrictions in place.
🚧 Early November to mid-December: The eastern end of Silver Road will temporarily close while it is connected to the new roundabout. Local access will remain available via the western end, with pedestrian and emergency vehicle access maintained.
🚧 Late November to mid-December: Night works will take place for asphalting between 7pm and 6am, Sunday to Friday.
🚧 From early November: Bus Stop 48a on both sides of Mount Barker Road will be permanently removed. Passengers can use Bus Stop 49 instead.
Access through the new roundabout via Mount Barker Road and Silver Road is expected to open from late 2026, weather permitting. Work on the new westbound freeway exit ramp will continue, with that connection expected to open in 2027.
DIT advises motorists to allow extra travel time, follow traffic signs and take care when travelling through the area.
Some noise, vibration, dust and additional lighting can also be expected during construction.
These are DIT works, not Council works. For more information or questions about the project, contact DIT directly:
