What's happening
You can read the September Construction Update.
Traffic realignment on Mandurah Road
From late September 2025, as part of continued road construction and clearing for amenity walls with the north-east of the project, traffic will need to be realigned on the western side of the bridge:
- Westbound traffic will be directed onto the new approach road after the existing bridge.
- Eastbound traffic will remain in the right-hand lane after the merge point from Old Coast Road and then move back into the left-hand lane before crossing over the bridge.
This will enable necessary working room for noise wall installation and build the new median strip between old and new approaches.
Movement of site compound
Our temporary site offices including car park will downsize in October 2025 to enable construction of the new accessible car park off Waterside Drive. A temporary office and car park facilities will be established on the adjacent land.
From 15 September 2025 until project completion, the reserve area including the playground will be temporarily closed.
Amenity wall construction
Vegetation clearing has begun in the south east area, to allow for the construction of amenity walls. Clearing will then begin along Mandurah Road, adjacent to Leisure Way, to allow for the walls in the northwest towards the Old Coast Road traffic intersection. Please refer to the amenity wall clearing - construction update for amenity wall clearing maps.
Existing fishing platform closure
The existing fishing platform remains closed for safety reasons, unrelated to the Mandurah Estuary Bridge Duplication Project works.
Members of the community are requested to refrain from accessing the construction area to access the fishing platform. Fishing and swimming from within the construction area is not recommended.
Roadworks
Egret Point Road between Wedgetail Retreat, Halls Head and Seahawk Drive, Erskine
Ongoing
- Intermittent traffic management will be in place for the remainder of the project
- There may also be times when a road closure is required, which will be communicated with road signage and via construction updates in advance
- Local traffic west of the existing bridge will be detoured to Old Coast Road from Bower Drive, while local traffic east of the bridge will be detoured via Leisure Way in the event of a road closure

24/7
- Westbound traffic will split either side of the median strip just after the Leslie Street traffic light intersection.
- One lane of westbound will sit in the right-hand lane of the existing eastbound carriageway.
- The other westbound lane will sit in the right-hand lane of the existing westbound carriageway.
- The lanes will return to a side-by-side configuration just before the eastern side of the bridge.
- Speed reduction to 60km/h.

Marine Works
Estuary Construction Area - 150m either side of the existing bridge
Ongoing
- A reduced 5-knot speed limit is in place
- Please follow the ‘no wake, no wash’ principle
- The navigational channel passing underneath the bridge, between piers four and five, has been reduced to a 30m width
- Estuary users are reminded that works continue in the water, therefore please approach the navigational channel with caution as it is a live construction area
- All marine traffic, including non-motorised vessels, must use the main navigational channel when traversing the bridge and follow markers and temporary buoys that are in place in the estuary
