The Western Highway is closed Melbourne-bound between Ararat and Ballarat, due to a serious collision at Trawalla.
All Melbourne-bound traffic is being diverted onto the Pyrenees Highway through to Avoca. Then, drivers can use the Sunraysia Highway through to Ballarat.
Drivers should allow an extra thirty to forty minutes using this significant diversion.
This closure is under Victoria Police control. The road will re-open when investigations are complete and it is safe to do so.
