Collie to Mumballup Road Upgrade
Greer Road to Donnybrook-Boyup Brook Road
We’ve upgraded the road width from the existing six metre seal to ten metres. We installed one to two-metre wide sealed shoulders on each side of the existing road.
As the terrain along this road undulates in some areas, further design investigation will be undertaken to address some land, services and minor alignment improvements along the road.
Where possible, we will enhance safety by protecting or eliminating roadside hazards, such as large trees and steep embankments.
