12 March 2025

Three new signs with automated flashing yellow lights were installed in December 2024 to warn drivers at the following intersections:

  • Tynong-Bayles road/Main Drain Road
  • Toner Road/Main Drain Road
  • Eleven Mile/Main Drain Road.

The lights on the signs start to flash when the Bunyip River (also known as the Main Drain) rises to a height just below the road surface.

We will continue to close the exclusion gates when floodwater is expected to go above the road. At these times, drivers will need to continue following the detour signage.

On average, the gates are closed about twice a year.

Location of signage

The yellow points on the following map show the location of the new signs.


Upcoming temporary road closures at Cora Lynn Ford

Drivers in the area may notice temporary short term closures of the road near the Cora Lynn Ford during March 2025 whilst we repair the exclusion gates. Please follow the detour signage when in place.
