Karnup Road is now open to traffic following the completion of culvert repair works.

Motorists are reminded to follow traffic management and speed limit instructions. Tidy up works will also be carried out around the area.

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.
