Automated Flooded Road Warning Systems (AFRWS)

Brisbane City Council is expanding the Automated Flooded Road Warning Systems (AFRWS) initiative to enhance road safety during periods of heavy rainfall. This initiative is part of Council’s commitment to reduce the risk of motorists driving into floodwaters.  

AFRWS are automated signs that display early warning messages to motorists about potentially hazardous flooded road conditions. AFRWS are positioned on the approach to flood risk locations and the sign remains blank until activated by floodwaters. This provides Council’s officers time to respond and install temporary detour signage and barriers, depending on the nature of the event.

AFRWS are solar-powered systems with a water level alarm gauge, which triggers a highly visible LED message of ‘Road Closed Ahead' when the road is flooded. Where possible, new installations will also feature a camera to allow Council to monitor the flooded road remotely.

New locations

To improve motorist awareness of road conditions during heavy rainfall, Council will install solar powered AFRWS at the following locations throughout the 2022-23 financial year.

  • Bowhill Road, Durack (Hanleys Creek)
  • Bracken Ridge Road, Bracken Ridge (Bald Hills Creek)
  • Formosa Road, Belmont (Between Stanbrough and Dairy Swamp Roads)
  • Grandview Road, Pullenvale (Pullen Pullen Creek)
  • Kholo Bridge, Kholo (Brisbane River)
  • Gap Creek Road, Kenmore Hills (extra signs at Gap Creek)
  • Lancing Street, Pullenvale (Pullen Pullen Creek)
  • Paradise Road, Willawong / Larapinta (Oxley Creek)
  • Rafting Ground Road, Brookfield (Moggill Creek)
  • Sherwood Road, Rocklea (Oxley Creek)
  • Victoria Street, Newmarket (Enoggera Creek)
  • Wynnum Road, Tingalpa (Bulimba Creek).

This project received grant funding from the Australian Government to install three additional AFRWS at known flooded roadway locations:

  • Gap Creek Road, Kenmore Hills
  • Bowman Parade, Bardon
  • Lucy St / Station Road, Moorooka.

These three systems will be installed in the 2022/23 financial year.

Existing locations

Some existing systems may use mains powered AFRWS and have flashing lanterns that warn motorists about flooded road conditions. These are in place at ten locations across Brisbane:

  • Bilsen Road, Zillmere (Zillman Waterholes)
  • Boscombe Road, Brookfield (Moggill Creek)
  • Groth Road, Zillmere (Zillman Waterholes)
  • Marshall Road, Rocklea (Stable Swamp Creek)
  • Melton Road / Widdop Street, Nundah / Clayfield (Kedron Brook)
  • Muriel Avenue, Rocklea (Rocky Waterholes)
  • Newman Road roundabout, Zillmere (Zillman Waterholes)
  • Rafting Ground Road, Brookfield (Moggill Creek)
  • Shaw Road, Wavell Heights (Kedron Brook)
  • Trouts Road, McDowall (Downfall Creek).
