Collie to Mumballup Road Upgrade
Greer Road to Donnybrook-Boyup Brook Road
We’re upgrading the road width from the existing six-metre seal to ten metres with one to two-metre wide sealed shoulders on each side of the existing road.As the landscape in this area tends to rise and fall, we have steepened the roadside batter in order to retain vegetation and minimise environmental impacts. 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.
