MOTORISTS are advised of changed traffic conditions for maintenance work on the Thirroul overpass later this week.

The northbound lane on Lawrence Hargrave Drive between George Avenue, Bulli Hill, and Bulli Pass will be closed for bridge joint cleaning and the clearing of drainage ports.

Work will be carried out between 8pm and 5am from Sunday October 20 to Thursday October 24, weather permitting, to minimise impact to motorists. Stop and Slow traffic control and a reduced speed limit of 40kmh will be in place for the safety of workers and road users.
