Northern toll plaza precinct upgrade - Sydney Harbour Bridge precinct


Project overview

The experience of being on the deck of the Sydney Harbour Bridge is now more accessible with lifts to the bridge’s walkway now operational. On average, more than 2000 cyclist trips are taken across the Sydney Harbour Bridge Cycleway every weekday. That makes the Sydney Harbour Bridge Cycleway the busiest link in the Metro Sydney Bike Network. Transport for NSW is progressing plans to upgrade access to the Sydney Harbour Bridge cycleway. Roads and Maritime uses innovative technology to monitor the condition of various parts of the bridge, help schedule maintenance and inspect difficult to reach areas of the Harbour Bridge. Roads and Maritime Services maintains all steelwork on the Sydney Harbour Bridge. Protecting the intricate web of steelwork from corrosion is the most important factor in conserving the structure. Transport for NSW will undertake remediation works on the slopes of the off ramp from the Bradfield Highway between Sunday 12 July and Thursday 8 October 2020. We are proposing to replace the arch maintenance units that crews use to perform routine inspections, repair work and painting on the Sydney Harbour Bridge. The new units will provide better and safer access so we can preserve this iconic structure well into the future. As part of the commitment to maintain the Sydney Harbour Bridge, Roads and Matitime conducts ongoing maintenance to ensure that this national icon is preserved for years to come. Transport for NSW is improving the northern toll plaza precinct. The improvement work includes removing the unused toll booths and toll office from the northern end of the Sydney Harbour Bridge. Transport for NSW has a coordinated approach to the continuous improvement and maintenance of the Sydney Harbour Bridge.

NOV 2020November 2020 community update

Our latest community update is available with information on the progress of the northern toll plaza precinct upgrade, new extended working hours and addendum to the Review of Environmental Factors.

Project information

The key features and benefits of the project include:

  • removing the northern toll booths, toll office and related infrastructure
  • simplifying traffic movements to remove road safety hazards and improve flow
  • resurfacing a section of the Cahill Expressway between the High Street overpass and Fitzroy Street in Kirribilli to provide an improved road surface
  • applying a consistent70km/hr speed zone between Warringah Freeway and the Sydney Harbour Bridge with the ability to introduce changeable speed limits when needed

To create a safe day time work zone on the northern approach to the Cahill Expressway, we will install temporary safety barriers and hoardings on the road. We will keep two lanes of traffic moving around the work zone for the majority of the work. Access onto and off the Cahill Expressway will largely remain the same during the day.

Some changes to traffic will occur at night or during weekend closures of the Cahill Expressway. At these times there will be changes to access from Kirribilli and travel times may be affected. Motorists should plan their trip and check Live Traffic for detailed detour information.

Please drive to the conditions and follow the directions of signs and traffic control.

Further closures may be required at times and we will notify the affected community. 

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

Our daytime work hours are 7am to 6pm, Monday to Friday, and 8am to 1pm on Saturdays. Night work will also be required to reduce impact to motorists. We will work up to five nights a week from 8pm to 5am,Sunday to Thursday.

This work will be noisy at times, but we will do everything we can to lessen its impact, including scheduling noisier work during the day and completing noisier activities, such as concrete cutting and jack hammering, by midnight.

We will also lessen impacts by using equipment fitted with noise controlling tools where possible and carry out noise monitoring at night.

A site compound will be used under the Sydney Harbour Bridge near the northern pylon of the bridge to support this work. This will reduce the need to take up space on the bridge deck itself.
