One of the region’s iconic timber bridges is getting some love and attention, extending its future and place in the landscape of South East New South Wales.

Coolumbooka River Bridge at Bombala is undergoing essential repair work this month to protect the heritage-listed structure.

A Transport for NSW spokesperson says the work will ensure the bridge remains safe for all motorists.

“Transport for NSW will carry out the work from Monday 26 August for about twelve weeks, weather permitting. While the bridge is safe to use, this work is needed to ensure the bridge continues to perform into the future for all motorists who use Cathcart Road,” the spokesperson says.

“Investigations carried out on the bridge on Cathcart Road discovered signs of deterioration on the underwater piles and the bridge trusses.

“Initial maintenance work was then carried out, and further maintenance is planned to retain the structural integrity of the historically significant structure.”

The first stage of work will involve installing temporary support piles and a steel support structure, stage two will see the installation of an additional bridge support system and the replacement of parts of the truss, scheduled for 2020.

The single lane, six-span bridge, connects Bombala to the coast, and was completed in 1892. It is one of the seven remaining McDonald timber truss road bridges in NSW and has a load limit of 42.5 tonnes.

Work will be carried out between 7 am and 6 pm Monday to Friday and 8 am to 1 pm Saturdays.

During the first six weeks of work, the bridge will close to traffic during work hours and detours will be in place.

Motorists will be pointed towards the detour via Black Lake Road and the Monaro Highway and are advised to allow up to 35 minutes additional travel time.

For the remaining six weeks of work, intermittent bridge closures of up to 30 minutes are expected, as steel structures are installed to support the new bridge piles.

Transport for NSW says the community will be kept informed during the work.

Changed traffic conditions including traffic control and a reduced speed limit of 40 km/h will also be in place on Cathcart Road during work hours.

“Transport for NSW thanks motorists for their patience during this important work,” the spokesperson says.
