New bridge reaches halfway across the estuary
With nine segment launches now complete, the new westbound bridge is now halfway across the estuary. You can now see the girder and nose reaching over the estuary navigation channel where boats can pass underneath. There are no safety issues in passing beneath the segments for estuary users. A Vessel Management Plan remains in place with a reduced width of the navigation channel and a 5-knot speed limit to ensure the safety of workers and equipment.
Ongoing clearing and works for amenity walls
Noise wall footings and panel installation will occur to the southwest area of the Project on the approach to Old Coast Road from Monday 14 April. These walls will run from just past the area adjacent to Arkley Court through to the bridge embankment on the western side of the estuary.
From early to mid-April clearing associated with the construction of these amenity walls will get underway to the northeast (Waterside Drive) area. These works are expected to take up to two weeks to complete with noise wall footings, CFA piling and panel installation is expected to occur from early-to-mid May 2025.
Clearing and other works for southeast (Waterlily Drive) and northwest (Leisure Way) will occur mid-to-late 2025.

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
