Changed traffic conditions in Mount Annan, Smeaton Grange and Harrington Park

 Road users are advised of changed traffic conditions on Narellan Road west of Waterworth Drive, Mount Annan, Camden Valley Way south of Anderson Road, Smeaton Grange, and The Northern Road south of Fairwater Drive, Harrington Park.

The changes are necessary to install three new Variable Messaging Signs (VMS) as part of the Network Efficiency Program.

Initial work to install foundations is for up to 15-night shifts (five nights at each location) between Monday 8 September and Tuesday 30 September 2025, weather permitting.

Installation of the VMS boards and testing is for 12-night shifts (four nights at each location) between Wednesday 1 October to Thursday 30 October 2025. Our night working hours will be between 8pm and 5am.

There will be five-day shifts for final testing once VMS boards are installed. Our day working hours will be between 7am and 5pm. 

No work will occur Friday or Saturday nights, or public holidays. 

There will be temporary traffic changes while we complete this work. This includes lane closures and a reduced speed limit of 40km/h. 

Please drive and ride to the conditions and follow the directions of signs and traffic controllers. 

Thank you for your patience during this time.
