Windsor Bridge replacement

The NSW Government is funding this project to help improve traffic flow and provide a reliable and safe crossing of the Hawkesbury River.

Windsor Bridge
The building of the bridge decks is now underway.

Updates and announcements

Work to be carried out in August 2019 includes:

Bridge construction

We are continuing to launch the bridge segments as they are constructed. We have now launched six out of the ten deck segments. The seventh pour will take place within the first two weeks of August, (weather permitting).

We are continuing to build the abutment and retaining walls on the southern side of the river, as well as the retaining wall for the future wharf carpark.

Construction of the bridge piers is complete and the piers are receiving the bridge as it is launched across the river. The access platforms around the piers will remain throughout the launching process.

Utility relocations

We will upgrade the electrical network on the north astern corner of George Street and Bridge Street. This will entail transferring the power supply from overheads to underground.

For this upgrade we will install:

  • new electrical joints,
  • a new pole
  • two new electrical pillar boxes.

We will also remove three existing poles from the area.

We also need to carry out some relocations on Bridge Street between Macquarie Street and George Street. This work will include installing:

  • underground conduits
  • pits
  • poles and footings

We will carry out some of this work at night for the safety of workers and road users, and to minimise the impact on the road network. We will notify any affected residents separately before any proposed noisy or night work.

We will also remove an existing water main along the southern side of Wilberforce Road. Work will include some investigation and preparation work to connect existing customer services to the larger existing mains.

New utility services are being installed under each segment of the bridge, and then launched out with each bridge segment.


Work will continue near the intersection of Bridge and George Streets.

This work involves roadwork and landscaping and will continue east of the new bridge from the George and Bridge streets intersection, downhill to The Terrace.

The work behind the safety barriers continues and includes archaeology, building new road surfaces, installing services and overhead electrical work.

Work will continue on the northern side of the river, including widening the shoulder in the project area on Wilberforce Road. This work will include:

  • new line marking
  • earthwork
  • asphalting
  • drainage
  • removing concrete barriers

We will carry out some of this work at night for the safety of workers and road users, and to minimise the impact on the road network

We will notify any affected residents separately before any proposed noisy or night work.


Archaeologists continue to work in the project area. We will continue with archaeological monitoring and salvage on Bridge Street.


We expect to continue to demobilise the barge through to the end of the month. We will shift the floating pontoon access to the piers, depending on the barge location, so we maintain a safe navigational channel through the work area.

Our work schedule

Work will generally be carried out during standard construction hours between 7am and 6pm on weekdays and from 8am to 1pm on Saturday.

There will be some out of hours work through August along Bridge Street between 9pm and 5am Monday to Friday.

There will also be some extended hours on Saturday from 8am to 4pm.

How the work will affect you

There may be some noise and disruption associated with this work including vehicle movements. We are continuing to make every effort to minimise noise and disruption to the community during construction.

Temporary traffic changes will be in place to ensure the work zone is safe. Please follow the direction of traffic controllers and signs.

For the latest traffic updates, you can call 132 701, visit or download the Live Traffic NSW App.

Thank you for your patience during this important work.
