Dalwallinu and Wubin

The Dalwallinu and Wubin package includes modifications of the intersection in Wubin, realignment of Great Northern Highway in Dalwallinu and improvements to the Peterson Road and Great Northern Highway intersection.

The Wubin Bypass construction has been deferred.  Land acquisition, environmental approvals and design will be completed for the Wubin Bypass. Deferring the Wubin Bypass will remove the potential risk of 53.5m road trains travelling south of Wubin prior to the construction of Bindoon Bypass.

Scope of works

  • Upgrade to the Great Northern Highway intersection in Wubin to allow future southern access for 53.5 m road trains, access to local facilities and the Road Train Assembly Area
  • Realignment of the highway in Dalwallinu including elimination of the tight curve at Clinch Road and intersection improvements
  • Upgrades at the Peterson Road intersection
