What's happening
Read the March Construction Update.
Amenity wall clearing
Read the full update and view the clearing maps for the amenity walls here.
From Monday 17 March, removal of vegetation will commence in the furthermost southwest area of the Project on the approach to Old Coast Road, plus a small area will be cleared in the southeast quadrant on Waterlily Drive at the same time. These works are expected to take up to two weeks to complete.
Clearing is also expected to commence to the northeast from early April, the southeast from mid-June (adjacent to Waterside Drive and Waterlily Drive) and the northwest in September to make room for the construction of the amenity walls.
The Project includes revegetation of the cleared areas once construction is completed.
Lane realignment - Mandurah Road eastbound
Please be aware that ongoing lane realignments will be required for the remainder of the project. Drivers are urged to be aware of modified lanes and signage.
Around late-March, eastbound traffic travelling from the existing bridge towards the Leslie Street intersection will shift laterally to the north to create working room in the southeast quadrant. A speed reduction to 40km/h will be in place during the traffic implementation being performed on nightshift.
These road conditions will remain in place until mid-June 2025. Nightworks will also occur during this time to update temporary roadside barrier, w-beam barrier, road markings and signage.
Barriers will also be installed that will result in a single lane for eastbound traffic from Old Coast Road to the Leslie Street intersection. This is required to provide safety buffer for workers to complete northeast amenity wall extension works.
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 16 March if necessary
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.

Lane realignment - Mandurah Road and Old Coast Road
- From mid-February, eastbound traffic will be required to merge earlier after the traffic light intersection with Old Coast Road to enable median works to begin
- Eastbound traffic remains at one lane, with westbound traffic operating two lanes.
- All traffic has been laterally shifted north.
Path Detours
Waterside Drive to Mandurah Road shared path
Ongoing
- Shared path closed to install temporary barriers
- No access to and from Waterlily Drive to Mandurah Road for the duration of the project.

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
