​What's happening?


Current status - Construction started in April 2018 and is due to be completed in mid-2019

The southern offline portion of works is moving into the final stages of pavement construction. Construction has commenced along Northam-Pithara Road and a temporary side track will be constructed in order to complete the southern section and the Northam-Pithara Road / Great Northern Highway intersection.

Works through the Water Corporation Reserve continue, with a significant amount of northbound works complete. After sealing, traffic will be shifted onto these works to enable construction of the southbound lane.

Works in Pithara town are progressing well with the drainage network complete and pavement works commencing including the construction of the Roach and Bonnie Street cul-de-sacs.
A temporary side track north of Pithara is now in operation with a speed limit of 60 km/h to enable the construction of the northern section of works.

Contractor, HAJV were recently awarded ‘Team of the Year’ by Nudge, in recognition of their efforts and commitment to train and employ trainees. See our December 2018 project update for more information.

Works include:

  • 10.3 km of new highway, to be built next to the existing highway south of the Northam–Pithara Road;
  • 5.7 km of highway widening and upgrade; 
  • 1.5 km upgrade of Northam-Pithara Road
  • New overtaking lanes;
  • Intersection improvements at Sheoak Road, Moller Road, Crampton Street, Northam-Pithara Road, Pithara West Road and Pithara East Road.

Modifications are planned for the road layout in the Pithara townsite including new bus bays for intrastate bus services. The existing intersections of Roach Street and Bonney Street with Great Northern Highway will also be transformed into cul-de-sacs to improve road safety in town for local and highway traffic.

Bindoon Bypass

Current status - Planning

Progress continues on preliminary planning for the 66 km bypass of Bindoon up to New Norcia. One of the key constructions approvals, the Public Environmental Review document for the southern section, was submitted in August 2018 and will be available for public comment early this year. Remaining statutory environmental approval applications for the 18 km northern section from Calingiri Road to New Norcia are expected to be submitted in January 2019. This section is expected to require a referral under the EPBC Act 1999 at a Federal level, and a clearing permit under the EP Act 1986 at a State level.

A strategic review of road connections to the Bindoon Bypass was completed in September 2018, allowing the land requirements for the road reserve to be progressed. Land acquisition processes continue on four significantly impacted properties along the proposed Bindoon Bypass.

With Federal funding of $220 million announced towards the $275 million Bindoon Bypass, 53.5 metre road trains may soon be able to travel south to Muchea. We will commence formal land acquisition processes for all properties and provide an indicative construction schedule once State funding is confirmed.


Miling Straight

Finishing works will continue over the coming months to complete side roads, drainage and landscaping.
