Motorists are advised of changed traffic conditions on the Bruxner Highway for slope repair work.

Work is being carried out near Piora, about 21 kilometres west of Casino, from 7am to 6pm weekdays and from 8am to 1pm Saturdays.

The work is expected to take three weeks to complete, weather permitting.

Some lane closures will be in place, with traffic control and a reduced speed limit for the safety of workers and road users.

Motorists are advised to drive to the conditions, and follow the directions of signs and traffic control.

Transport for NSW thanks road users for their patience during this time.
