Work will start next month on major repairs to restore full access to all traffic on Moss Vale Road at Cambewarra Mountain, with detours for heavy vehicles expected to add 90 minutes to each trip.
Specialist contractors have been appointed to complete repairs to landslip damage caused by record-breaking rainfall in 2022.
Weather permitting, work will begin on Tuesday 2 April, with $5 million going towards the repairs, from the Australian Government’s Disaster Recovery Funding Arrangements (DRFA).
The terrain and landslip damage posed unique challenges and risks during the planning process, which Transport for NSW will continue to navigate as work is carried out.
For the safety of motorists and workers, the road will be closed to traffic while work is carried out at night between 7pm and 5am Sunday to Thursday, when traffic volumes are lower.
To maintain traffic access for those who need to use the road, work will be briefly suspended for five-minute periods at 8pm, 9pm, 10pm, 12am, 2am and 4am.
Motorists are advised to drive to the conditions and follow the directions of signs and traffic control.
Detours for light vehicles will be via Kangaroo Valley Road, adding 25 minutes additional travel time. Vehicles longer than 7.5m or heavier than 12t GVM will have to detour via the Illawarra Highway and Princes Highway, adding 90 minutes of extra travel time.
