Due to severe weather conditions, essential maintenance work on the Kings Highway at Clyde Mountain will continue into November.
Fog in the area is delaying the essential work, which includes slope stabilisation in response to recent rain.
The Kings Highway will continue to be closed in both directions between 6pm and 6am Monday to Thursday until at least Thursday 5 November.
Day work will also continue until Friday 6 November, weather permitting.
During the night closure, detours for light vehicles will be via the Princes Highway and Nerriga Road and are expected to add up to 1 hour 45 minutes to journeys.
Detours for heavy vehicles during the night closure will be via the Princes Highway, Picton Road, the Hume Highway and Snowy Mountains Highway and are expected to add up three hours to journeys.
Work will continue to be carried out in the day between 6am and 6pm, Monday to Thursday and 6am and 12pm on Fridays.
During day time work hours, traffic control, lane closures and a reduced speed limit of 40 km/h will be in place for the safety of workers and motorists.
Delays of up to 10 minutes can be expected.
Work is scheduled to be complete by Friday 6 November, weather permitting.
Motorists are advised to drive to the conditions and follow the directions of signs and traffic control.
