What's happening
Read the August Construction Update.
Removal of the segment casting yard
The bridge segment casting and launching process will end this month as the bridge reaches its final position at the western abutment. The casting yard adjacent to Waterlily Drive will then be demobilised. Nearby sand stockpiles will be used to backfill the entire area and build up the road carriageway so that eastbound traffic can be aligned with the new bridge deck.
Amenity wall construction
Vegetation clearing is expected to start in the southeast quadrant starting early August. The clearing is occurring to allow for the construction of amenity walls. Following this, clearing will then be performed along Mandurah Road, adjacent to Leisure Way, to allow for the walls in the northwest towards the Old Coast Road traffic intersection. Refer to the amenity wall clearing - construction update for amenity wall clearing maps.
Working outside of normal hours
- Split shifts between 5am and 9pm may occur for activities that enable concrete pours, crane operations and bituminous pavement works.
- Works may occur on Sundays throughout August if necessary (weather dependant).
- Night works to complete patching and the internal services fit-out of the bridge structure continue until the end of August.
- Night works to complete installation of light poles and cabling to northeast and northwest quadrant.
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 and swimming from within the construction area is not recommended.
