MOTORISTS are advised of changed overnight traffic conditions from next week on Nelson Bay Road at Salt Ash to progress the upgrade from Williamtown to Bobs Farm.

To minimise impact to motorists, line marking work will be carried out from 6pm on Tuesday 24 to 6am on Wednesday 25 January, weather permitting.

Lane closures, traffic control and a 40km/h reduced speed limit will be in place during the night work and may affect travel times.

Short term stops may be required at times.

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

Transport for NSW thanks motorists for their patience during this time.
