Full bridge and lane closures – Tarban Creek Bridge rehabilitation, Hunters Hill starting Friday 1 May 2015

The NSW Government is funding this essential night work on Tarban Creek Bridge, between Hunters HIll and Huntleys Point, to ensure it continues to meet current and future demand as a vital traffic link in Sydney's North. Read more (PDF, 262Kb).

Project background

Tarban Creek Bridge forms part of the northern approaches to the Gladesville Bridge. The bridge is an iconic structure spanning Sydney Harbour. The main arch of this bridge is a complex and distinctive structure, spanning approximately 90 metres. The bridge was opened to traffic in 1965.

Tarban Creek Bridge needs to be rehabilitated to address two issues:

  • The durability of a repair system installed in 1970
  • The deteriorated support beams and bearings identified during an inspection in 2008.

The NSW Government has fully funded this project to ensure the bridge performs well in the future.

The importance of design

Roads and Maritime recognises the high value scenic quality of this bridge and its setting in Sydney Harbour. It is important to waterway users, residents and people who appreciate design.

Roads and Maritime investigated a range of potential options to strengthen and maintain the bridge. Full details are provided in the Tarban Creek options report.

As a result of this investigation, Roads and Maritime shortlisted three feasible options.

Engineers and designers worked closely on all options. An urban design and visual impact assessment was also prepared. It forms Attachment A to the Options report.

Roads and Maritime reached a view as to an option that we felt best suited the bridge aesthetically. However, the community's views are just as important.

Community engagement

To ensure that the most appropriate design option was selected, Roads and Maritime sought the community's views on options for this rehabilitation. For details of this community consultation, see the June 2012 Community update.

Roads and Maritime examined all submissions made during the consultation period and published a Community issues report which identified the issues raised in submissions.

A clear majority of submissions (83%) indicated a preference for Option one – portal frame with rectangular tapered piers located outside the existing arches. Roads and Maritime took this preference into account as it finalised the detailed design for the work.

Review of environmental factors

Following community consultation and environmental assessment and investigations, Roads and Maritime published the Review of environmental factors (REF) in 2013 and determined its preferred option for the rehabilitation of Tarban Creek Bridge in Hunters Hill.

The Review of Environmental Factors described and assessed the potential impacts of the proposal on the environment.

The report identified Option one (portal frame with rectangular tapered piers located outside the existing arches) as the Roads and Maritime preferred option with the neutral coloured new piers. This decision took into account community feedback and, environmental and design issues.

Option one was considered to best meet the project's objectives. In comparison to the other options, Option one provided an effective repair and has been designed to be relatively open in structure minimising the visual impact. This preferred option was also buildable and maintainable.


The project is progressing well towards a revised completion date of April 2015, weather permitting. Work started in September 2013 and significant progress has been made in the first 15 months of construction:

  • The foundation works at the north and south abutments are complete
  • The columns and headstocks at the north and south abutments are 90% complete
  • The new bearings are installed at the south abutment.

Night work and bridge closures are scheduled for January and February to repair and install the new bearings. There will be some noise associated with this work, but every effort will be made to minimise the impact on residents and businesses. The local community will be kept informed as the project progresses.
