What's happening

 The works

The construction team will continue its work in May to remove the median strips from Mandurah Road.  We aim to complete these works in the second week of May.

There may be an impact on traffic, but we will endeavour to carry out the works during off-peak traffic times to keep delays in travel times to a minimum

Some of the works include:

• Reclamation pad construction 

Temporary reclamation ‘working pads’ are being constructed on the banks of the estuary, one on each foreshore to provide a base from which to build the outermost piers for the new bridge.
These working pads are temporary earth structures that help with the construction of piers in shallow water. the first of these will be built on the eastern foreshore.

• Egret Point embankment works

An embankment is being prepared in this section to support the future bridge superstructure build, and to allow construction of drainage and noise walls.

We will excavate and utilise fill material from Waterlily Drive where the casting bed construction works are commencing. This work will continue throughout May and June. During this time, you might hear noise and feel vibrations.

• Beach access closure

Footpath users are advised that beach front access on the eastern foreshore will be closed from early May as the project continues to progress into the estuary.  We understand that this will impact path and foreshore walkers and alternative routes and detour will be provided that takes users to the crossing at the Leslie Street – Mandurah Road traffic lights.

• Team dives into dolphin knowledge

The project team recently had a site visit from dolphin researcher Dr Krista Nicholson and Robyn from the Estuary Guardians group. They delivered a highly informative toolbox talk and education session about the dolphins in the Mandurah Estuary and surrounding waters.

The pair gave some great insights to the local dolphin population, which numbers around 85.

Mandurah’s population of Indo-Pacific bottlenose dolphins reside in the Peel-Harvey Estuary all year round. They choose to call it home due to the abundance of fish, the calm and warmer waters and absence of predators.

The project team is focussed on mitigating potential impacts on dolphins and other aquatic species during construction works and it will use mammal observer to ensure dolphins are not present within the pile-driving areas during construction of the piers.

Project workers are also currently raising funds for the “Estuary Guardians” through the Containers for Change program. More about Estuary Guardians https://www.estuaryguardians.com.au/
