Anyone expecting to be driving through the crash scene should exercise caution and allow additional travel time.
There is no word on what caused the crash or whether anyone was injured in it. However, the RMS's Live Traffic website says there are currently emergency service crews and Roads and Maritime Services officers on the scene.
