Repairs to notorious Brown Mountain landslip sites to start

A Transport for NSW spokesperson said since the highway was damaged during the severe weather events in early 2022, Transport for NSW has been investigating and designing solutions to repair a number of sites.

"Brown Mountain is a key route for freight, locals and tourists travelling between the Snowy Mountains and the Far South Coast of NSW," the spokesperson said.

"Repairs will start on three sites next week to help get this section of the road back to pre-disaster condition and ensure it is more resilient to future severe weather.

"Work will involve reinforcing failed slopes at these three sites between Piper's Lookout and the Brown Mountain Power Station, about nine kilometres west of Bemboka."

The spokesperson said design solutions were also currently being developed for other sites damaged during the severe weather events, with work on those expected to start later this year.

"Transport for NSW carried out extensive investigations last year to understand the factors that led to the damage and inform designs that will ensure robust and resilient repair solutions.

"These investigations included flying drones equipped with LiDAR cameras capable of producing high resolution 3D maps of the mountain slope terrain, as well as borehole drilling down to 13 metres to gather information about the ground and soil formation.

"Transport for NSW will notify the community when further work will be carried out and will plan repairs to ensure impacts to traffic are minimised wherever possible."

Work will be carried out from 6am to 6pm on weekdays from January 31 and was expected to be completed by early March, weather permitting.

Single lane closures with traffic lights and a reduced speed limit of 40kmh will be in place 24 hours a day.

Transport for NSW thanked motorists for their patience during this time.
