OCT 2019Proposed design change to improve traffic flow

Roads and Maritime Services is proposing two minor design changes for the construction of Windsor Bridge.

The Windsor Bridge Replacement Project Environmental Impact Statement (EIS) was exhibited in November 2012 and received planning approval in December 2013.

More than seven years have passed since the traffic assessment was completed as part of the EIS. While we have continued to develop and build the new bridge, we have also taken the opportunity to carry out updated traffic studies in 2017 and 2019.

The new traffic modelling indicated a change to the existing design would allow traffic to flow better northbound during the afternoon.

Project information

For northbound traffic, the project’s current design has one lane turning left from Bridge Street into George Street and one lane going straight through and over the new bridge. Roads and Maritime Services is proposing two minor design changes that our traffic modelling shows would improve northbound traffic flow and reduce congestion and travel times for all road users.

  1. Two through lanes at the northbound approach of the Bridge and George streets intersection
    Instead of only one northbound lane going straight through and over the new bridge, vehicles will be able to go over the bridge from both the left and right lanes. This would improve traffic flow and reduce travel times by allowing two lanes of northbound traffic to move through the intersection at a time, rather than one.
  • Left lane: shared left turn and through lane
  • Right lane: dedicated through lane.
  1. A new merge lane exiting the Bridge and George streets intersection
    With two lanes of traffic travelling through the intersection, there would be a merging area on the other side of the intersection to merge the traffic back into a single lane

  • a 100 metre long merge lane
  • the extra lane merges into one northbound lane on the new bridge.

This change would improve traffic flow by allowing two lanes to travel through the intersection, then merge before reaching the new bridge. The updated traffic studies showed this minor adjustment could significantly reduce afternoon peak congestion for northbound vehicles. From the Bridge and George streets intersection, the predicted waiting times during the afternoon peak would reduce from 62 seconds to 20 seconds, based on predicted traffic volumes in 2026.

The proposed design change would have the following benefits for traffic:

  • improved northbound traffic flow through the Bridge and George Street intersection
  • reduced delays in afternoon peak including at the Bridge and George streets intersection
  • improved travel times and reliability and reduced queue lengths in the afternoon peak
  • the predicted waiting times during the afternoon peak would reduce from 62 seconds to 20 seconds, based on predicted traffic volumes in 2026.

The Department of Planning, Infrastructure and Environment (DPIE) will publicly display the Windsor Bridge Replacement Project design modification report until 7 November 2019.

The final bridge launch was completed on 16 September 2019, ahead of schedule.

Concrete work will continue at each abutment to complete the bridge approaches.

Now that we have launched all bridge segments, we will continue to remove the concrete casting bed from the northern end of the new bridge and its supporting structures.

The marine access platforms will remain in position as we reconfigure the bridge bearings, scheduled to commence this month. Our floating pontoons may remain in place to provide access for this work.

The barge will remain in place in the project area.

We are upgrading the existing sewer infrastructure between the areas north and south of the river.

To complete this work new sewer infrastructure will be installed and tied into the existing sewer infrastructure.

We are also upgrading the electrical network along Bridge Street and surrounding areas.

This includes the decommissioning of some of the old streetlights and installing new streetlights and poles. We are installing new underground networks are also being installed to provide power for future services and some new electrical lanterns.

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 underground provisions for traffic control will continue to be networks along Bridge Street between Macquarie Street and George Street.

To support this we will install new:

  • pits
  • underground infrastructure
  • new footings for the new poles.

We will continue to notify affected residents separately before any proposed noisy or night works.

Work is continuing near the intersection of Bridge and George Streets includes footpath reinstatement and finishing paving work.

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

Work will commence to build the new road alignment on the northern side of the river. During this time there will be an increase in truck movements.

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

Archaeologists will continue to work in the project area when required.

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

The out of hours work will continue into October along Bridge Street between Macquarie Street and George Street between 9pm and 5am Monday to Friday.

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

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 (including lane closures, road closures and detours) will be in place to ensure the work zone is safe. Please follow the direction of traffic controllers and signs.

Thank you for your patience during this important work.

RMS have engaged with Western Sydney University to take photographs and video footage of the existing Windsor Bridge. Special permission has been granted to fly a drone over the existing Windsor Bridge around mid-October.

Please note: The Hawkesbury Paddle Wheeler continues to operate and will be picking up and dropping off passengers from a temporary mooring at Governor Phillip Park boat ramp wharf.
