Transport for NSW is working to repair landslip damage on the Snowy Mountains Highway at Brown Mountain as part of the natural disaster recovery response across the state’s road network.

A spokesperson for Transport for NSW said, “Work to repair the last Brown Mountain landslip site, damaged during the severe natural disaster events in 2022 and 2023 started Monday, September 29, 2025 and will be carried out over five months, weather permitting.”
The work will see long metal rods (soil nails) drilled into the slope to stabilise the slope material, before covering the slope surface with a concrete shell (shotcrete) that will prevent further erosion and improve overall slope stability.

Work hours are 7am to 6pm on weekdays and from 8am to 1pm on Saturdays.
Changed traffic conditions including single lane closures under stop/slow arrangements and a reduced speed limit will remain in place for the safety of workers and motorists.
Motorists are advised to drive to the conditions, allow an additional five minutes travel time and follow the directions of signs and traffic control.
