Great Northern Highway - Muchea to Wubin Stage 2 Upgrade



We are upgrading the 218 km section of Great Northern Highway between Muchea and Wubin, which forms part of the National Land Transport Network linking Perth metropolitan area and Fremantle Port with the north-west of Australia.

We have already replaced 11 km of highway through the Bindi Bindi bends at a cost of $35m and completed a 21 km section of new highway from Batty Bog to Walebing at a cost of approximately $65m.

In conjunction with industry partners Jacobs and Arup, we have also completed a comprehensive planning review of this link and prioritised a series of additional construction packages to be delivered between 2016 and 2019. To be managed by this Integrated Project Team, these works will significantly improve safety and amenity, and facilitate the future movement of road trains along this section of highway.

Among the improvements to be made include town bypasses, wider roads, more passing lanes, flattening crests and easing curves, safer roadsides, more rest stops and additional facilities for heavy vehicles.

This project is funded by the Australian and West Australian Governments. It will ensure that the highway is able to meet the requirements of all road users, including 53.5m road trains in the future.

Planning for Bindoon Bypass

During the planning review we identified that operating 53.5m road trains on the highway through Bindoon and on the steep grades of Bindoon Hill presented a significant challenge.  To resolve these issues, we considered several realignment and upgrade options in the vicinity of Bindoon Hill along with a number of alternative options between Muchea and Calingiri West Road.

As a result of these investigations, three bypass corridors were presented to the community and stakeholders for feedback. These options are outlined in our Bindoon Project Overview.

The consultation period closed on 3 July 2016 and we are now considering all feedback relating to a range of social, economic, heritage, environmental, traffic and transport constraints. We expect to make a recommendation for a preferred corridor to the Minister for Transport in August.

Once a preferred corridor has been endorsed by the State Government, the alignment will be refined in consultation with affected landowners and other stakeholders to minimise land impacts. Construction is subject to further funding.
