Main Roads is conducting a major safety upgrade on Great Eastern Highway from Bilgoman Road to Mann Street in Mundaring.
There will be intermittent single lane closures in both directions while the work is being carried out. The speed limit has been reduced to 60 km/h.

Work is expected to be complete by July 2017.
