We’ll be using this new community group page to post important information about the project.

 The works

The construction team will continue its work in April and the community will see activity on areas adjacent to the existing bridge.

Some of the works include:
  • Clearing

Removal of vegetation has recently recommenced. This is to enable works along Seahawk Drive and Leisure Way including the installation of drainage basins and ground preparation (preloading) for noise and retaining wall.

Additional clearing is also required along Waterside Drive and Waterlily Drive having been identified in the 85% design review. This clearing will provide for an improved footpath connection.

  • Mandurah Road night works

We are starting night works from Sunday 7 April that will run until the end of the month. These works are scheduled from 7pm until 5am to reduce the impact on road users at peak traffic times.

We realise and appreciate that this has a noise impact on those who live near to the project and on evening road users. Where possible, the noisiest activities are scheduled to take place earlier in the evening

  • Waterlily Drive

Once the importation of fill material has reached the right level for settlement, works will stop for approximately four weeks, significantly reducing noise and vibrations that have been felt recently.

Dust suppression agents have been applied in some areas to reduce the impact of dust on neighbouring residents. Temporary road barrier installation will occur around the casting bed area adjacent to Waterlily Drive prior to excavation works commencing in May. This activity will have some associated noise, vibrations and dust.

  • Waterside Drive

Residents are reminded there may be an increase in light vehicles on local streets in the area now that our site office is an active working environment.

Topsoil clearing to allow for foundation preparation and embankment works.

Temporary road barrier installation.

  • Seahawk Drive

Topsoil strip, clean up and ground preparation will continue along cleared areas. There may be noise and vibrations with drilling to install settlement monitoring equipment sensors.

Bus users are reminded that the area behind the bus stop heading west is an active construction area and to maintain safety, access is not permitted. Please use the existing path to access the bus stop.

  • Leisure Way/Egret Point Road

There will be ongoing geotechnical testing, noise modelling, vegetation and topsoil clearing. Temporary road barrier installation

  • Footpath detours

As we progress our works, we will need to close off footpath access to ensure the safety of the surrounding community and to comply with workplace health and safety requirements for our construction site.

This will affect some residents and pedestrians who access the estuary from the end of Waterlily Drive and also those crossing the road to access bus stops adjacent to Seahawk Drive and Egret Point Road. These closures will remain in place for the duration of the project. Closures and detours will be signposted and detour maps will be posted on the project website and Facebook page.

Originally constructed in the 1980s, the Mandurah Estuary Bridge was designed with future duplication in mind.

With population growth in Perth, Mandurah, Peel and the wider South West regions, the amount of traffic currently using current this bridge is causing congestion.

Now that a contractor to build the bridge has been named, the work towards preparing a detailed design phase is underway. The project, which involves the construction of a second, two-lane bridge, and preparation works towards the ultimate design of a six-lane bridge, will also include construction of a universally accessible recreational fishing platform.
