What's happening

Read the February Construction Update.

Amenity wall clearing

The Project team is exploring options to reduce clearing required to construct the additional walls within the Project area.

While there will be substantial clearing to the south-west as the walls approach the Old Coast Road intersection, our early design indicates less than anticipated clearing will be required along Mandurah Road adjacent to Waterside Drive and Waterlily Drive.

We anticipate initial construction works of the amenity walls will commence in April. Further communications regarding clearing, exact location of the walls and programming will be provided to residents as the design is finalised.

Mandurah Road traffic switch

From mid-February, eastbound traffic will be required to merge earlier after the traffic light intersection with Old Coast Road. This will enable the median works to begin, and all traffic laterally shifted north, creating space for workers to safely commence construction of additional amenity walls and future road alignment.

There will be some night works to remove and update signage relating to this traffic realignment on Monday 17 February.

Working outside of normal hours

  • Early start times will continue on specific days in preparation for concrete pours and associated bridge segment works
  • Ad-hoc works may occur on Sunday 2 February and 16 February if necessary
  • The installation of noise wall panels along Egret Point Road and Waterside Drive near the existing bridge will occur Wednesday 5 and Thursday 6 February from 7pm–5am. These works are scheduled at night to reduce the impact on traffic during the day. A contraflow traffic system will be implemented for eastbound traffic.
  • Traffic management signage and bollards will be removed on the night of Monday 17 February from 7pm–4am.

Existing fishing platform closure

Main Roads has advised City of Mandurah to close the existing fishing platform for safety reasons, unrelated to the Mandurah Estuary Bridge Duplication project works. Please visit City of Mandurah’s Facebook post  for more information. 

Members of the community are requested to refrain from accessing the construction area to access the fishing platform.

Fishing from within the construction area is prohibited.
