🚧 Mandurah Estuary Bridge Duplication Project June Construction Update 🚧
During April, central median strips were removed from Mandurah Road on both sides of the existing bridge to accommodate a shift in road lane configuration. These median works with asphalt and line marking are taking place, followed by some temporary steel barrier installation on Monday, May 6.
These works will be carried out during the day, and traffic management and lane closures will be in place. There may be an impact on traffic. Noise, vibration, and dust limit monitoring will be performed to ensure they are within the approved acceptable range.
Nearby residents can expect:
• Noise from machinery in operation, vehicle reverse beepers and some drilling to install the steel barriers.
• Vibrations may be felt in neighbouring properties while these works are performed.
• There may also be a slight odour from the asphalt activities.
Casting bed site access
Earthworks are underway to establish the casting yard and bridge construction area adjacent to Waterlily Drive, located in the Southeast quadrant. Additional site parking for workers, along with laydown and casting bed areas, will soon be established in this area. Smoke may be visible during piling works Earthworks, including the ongoing removal of surcharge fill (yellow sand), and any remaining vegetation clearing will occur to enable the final design for this quadrant. The casting bed will be set up with the pouring of a concrete foundation, pedestals and the construction of crane pads, plus the installation of temporary formwork.
Retaining walls (southwest first, then northeast)
Construction of limestone retaining walls will also be underway in mid-June. Works will initially start in the southwest quadrant (adjacent to Seahawk Drive) and northeast quadrant (Waterside Drive). The retaining walls adjacent to Leisure Way (northwest) will be constructed in late July. Limestone block deliveries will commence later this month. As part of the construction process, Georgio needs to lower the groundwater level to facilitate the construction of the walls.
Egret Point embankment works
The embankment area at Egret Point Road has now been built (preloaded surcharge) and will be left to ‘settle’ for at least three months. During this time, continuously monitoring ground and settling movement to ensure the geotechnical conditions are suitable for commencing bridge construction works. During this period, a dust suppressant will be applied to the material (yellow sand) to mitigate any air-borne dust issues for nearby residents.
