Charleyong bridge under construction

Charleyong Bridge

Roads and Maritime Services is building a new Charleyong Bridge over the Mongarlowe River, Charleyong. The bridge is located on Main Road 92 connecting Braidwood and Nowra via Nerriga. The project is jointly funded, with the NSW Government allocating $18 million and the Australian Government allocating $5 million for the project. Funding for the project forms part of the NSW Government’s Bridges for the Bush Program.

21 JAN 202021 Jan 2020 Charleyong Bridge and Nerriga Road closed

Charleyong Bridge and Nerriga Road closed between Braidwood and Oallen Road on Main Road 92 from Tuesday 21 January. 

Transport for NSW advises of emergency changed traffic conditions on Main Road 92, with Charleyong Bridge closed to all traffic including pedestrians until further notice.

Charleyong Bridge will remain closed until further notice, including over the long weekend for the safety of motorists. We are continuing investigations to determine the damage to the bridge and identify options for repair.

Due to the bridge closure, Nerriga Road will remain closed between Braidwood and Oallen Road. The primary detour route (vehicles under 15 tonnes) is via Oallen Road, Sandy Point Road, Cullala Road, Lumley Road, Braidwood Road and Kings Highway, adding 35 minutes to travel times.

Light vehicles can also use Charleys Forrest Road and Little River Road between Nerriga and Braidwood.

Heavy vehicles should use the Kings Highway or other approved routes depending on their load limit restriction and their origin and destination.

Motorists are advised to allow additional travel time, drive to conditions and follow the directions of signs and traffic control.

Transport for NSW thanks motorists and the community for their patience during this time and apologises for any inconvenience.

Motorists are advised to visit for the latest road updates and visit for updates on fire activity in your region.

OCT 2019Work progresses

Work on the new Charleyong Bridge on Nerriga Road has reached a new milestone with all bridge girders installed to support the bridge deck and platforms removed from the riverbed in time for the Macquarie Perch spawning season.

After the completion of girder installation by early September, the large working platforms required in earlier stages of bridge construction were then removed from the riverbed for the Macquarie perch spawning season, which runs from October to December.

Bridge work will continue during this time and rigorous sediment controls will be in place, with bridge deck pours continuing until mid-November, weather permitting.

Transport for NSW will continue to liaise with a wide range of government agencies, including the Department of Primary Industries to ensure the habitat is maintained.

Other progress on the project includes earthworks which are now more than 80 per cent complete and building the bridge abutments and piers.

Upcoming work includes building the bridge deck, installing bridge barriers and continuing road pavement construction.

The new bridge is expected to be opened in 2020, weather permitting. The community will be kept informed as the project progresses.

SRG Civil were awarded the major tender to build the new bridge in November 2018, with Queanbeyan-Palerang Regional Council delivering the new road approaches required as part of the project. Major construction of the road approaches began in July 2018 and works on the new bridge began in January 2019.

Project information

  • increased safety due to wider traffic lanes and improved road approaches
  • ability for Higher Mass Limit vehicles to use the bridge
  • reduction in expensive and ongoing maintenance costs
  • timber from the existing bridge will be treated and recycled for use by industry.
  • construction of a new bridge upstream of current bridge location on improved alignment
  • construction of about one kilometre of sealed approach roads
  • removal of tight unsealed curves
  • approach to tie in with Nerriga Road immediately west of Tomboye Road intersection
  • removal of the existing bridge.

A number of improvements were made to the design after the Review of Environmental Factors was displayed in July 2016. These changes include the addition of two u-turn bays and new pavement for a longer design life.

Please view or download the revised detailed design.

Roads and Maritime will continue to work closely with Queanbeyan-Palerang Regional Council, affected properties, agencies and other key stakeholders throughout the project.

The new bridge is expected to be open to traffic by mid-2020, weather permitting.

The community will be kept informed as the project progresses.
