Tunnelling of the 560 metre drive under the Brisbane River is now complete.
The tunnel boring machine's associated equipment is currently being removed from the tunnel and the machine is being serviced.
Work is now underway to prepare the tunnel for the 'pulling through' of the two new pipes - one for water and one for sewer. This will include grouting and sealing the tunnel, as well as laying out and welding the pipes together.
The majority of this work will take place from the worksite in Kingfisher Park, Kenmore.
The worksite in Mt Ommaney Drive, Jindalee will be temporarily closed while tunnel prepartory work take place. Residents will be notified in advance of works recommencing in the area.
Working hours continue to take place between Monday to Saturday, 6am to 6pm.
We will continue to keep the community informed as the project schedule progresses. Our latest project newsletter can be viewed here.

Project look ahead
Once the pipes have been installed, further work will be carried out to connect the new pipes to the existing infrastructure.
In Jindalee, the following work will take place in late 2017/early 2018:
- A new sewer creek crossing will be constructed across Jindalee Creek, which runs adjacent to the Centenary Highway Bikeway. This will connect to the new sewer main installed in late 2015.
- Connecting the new water main from the tunnel to the infrastructure in Mt Ommaney Drive. During connection work there will be water outages in the Jindalee area. Impacted residents will be notified prior to any water outages.
- A section of sewer main near the Centenary Highway will be relined to ensure on-going reliability.
In Kenmore, connection work will take place in late 2017, including:
- A 100 metre new sewer pipe will be installed in Kingfisher Park via open-trenching to connect the new tunnel pipe to the valve pit installed in 2016.
- An air valve and vent pole will be installed near the valve pit subject to approvals. It will be fenced and landscaped to Brisbane City Councils specifications to protect the visual amenity of the park.
Further details will be provided to the community as the work is scheduled.
- Construction noise in Kingfisher Park, Kenmore and Mt Ommaney Drive, Jindalee, including the operation of tunnelling machinery, truck movements including reversing safety beepers, and generators.
- Dust may be visible during shaft excavation and backfilling activities and will be monitored and managed at source, using water suppression, as required.
- Changed traffic conditions including reduced speeds on Gem Road and Sunset Road in Kenmore.
- Increase in truck movements in Kenmore (please see truck route map below) with approximately 15 truck movements anticipated per day.
How will impacts be managed?
We will work closely with residents impacted by construction during the project, as well as:
Monitoring noise levels to ensure work methods are appropriate.
A sound wall will be constructed around the worksite to suppress noise during night works.
Truck movements will be restricted to no later than 6pm daily to minimise noise during night work.
- Directing site lighting away from residential properties.

- Full restoration of Kingfisher Park, Kenmore and the area behind the Scout Hall in Jindalee, including landscaping will be carried out on completion of the project.
