Background information

After the record rainfall we experienced in July and the significant storm event and flooding, a drain pipe (culvert) under Karnup Road, Serpentine (near Wellard Street), failed and caused a sink hole on 21 July, 2021.

Following inspection of the drain, it has been identified that a 24-metre length of 2m x 1.5m diameter ribbed steel pipes have rusted out and require replacement.

Is Karnup Road still open to traffic?

No, the road has been closed to traffic as part of safety measures. Traffic management is now in place. This includes provision for emergency services.

Motorists are encouraged to allow extra time and follow traffic management signage.
