Motorists are advised of changed traffic conditions from next week for road safety improvements to be carried out on Big River Way at Clarenza and Ulmarra.

The work will involve repairs to the road surface and widening the road shoulders at the intersections of Swan Lane at Clarenza and McLachlans Lane at Ulmarra.

The work starts on Monday 17 August and will be carried out on weekdays between 7am and 6pm and Saturday between 8am and 1pm.

The work is expected to take two weeks, weather permitting.

Some lane closures will be in place in the area of work. Traffic control and a reduced speed limit will be in place 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.
