Flood Recovery

​Background of the event

A series of rainfall events across the State during February 2017 caused wide-spread flooding throughout the Great Southern Region.

The preliminary estimate of damages to State Government assets is $26.5 million, with over 60 per cent of WA’s oldest road network in the Great Southern Region sustaining damage.

Immediate temporary restoration works were undertaken on sections of the network that were closed or impassable and network connectivity was completed in March 2017.

General damage caused

The region’s east was impacted most and incurred the following major damage:

In total, damage to the Great Southern Region road network is estimated at $3 million, excluding bridge reinstatement works.  

Working with construction partners Fulton Hogan and a range of local sub-contractors, significant headway has been made over the past year with the majority of works almost completed.  Most significantly was the recent reinstatement of the Phillips River Bridge.  

All flood recovery related works are expected to be completed by mid-2018.

The bridge has a larger waterway area than the previous 1960’s timber structure and has been constructed to current engineering standards to withstand a one in 100 year flood.
