Motorists are advised of changed traffic conditions at the intersection of Lawrence Hargrave Drive and The Grove at Austinmer for safety upgrade work next week.

Work to replace the traffic light posts and control box will be carried out at between 8pm and 5am Sunday to Thursday from Sunday 5 February for about three weeks, weather permitting.

A single lane closure, reduced speed limit of 40 km/h and stop slow traffic control will be in place for the safety of workers and motorists.

Motorists are advised to allow five minutes additional 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.
