Muchea North

​We are planning to upgrade the busy 14 km section of Great Northern Highway from Muchea to Chittering Roadhouse. A dual carriageway will be provided for three kilometres north of the planned interchange at Muchea. We will also acquire the land to allow for the future development of a dual carriageway to Chittering Roadhouse.

Pending environmental approvals, construction work is currently expected to start in October and take about 18 months to complete.

Project scope and benefits

This project includes:

  • New highway built next to the existing Great Northern Highway, linking up with the proposed NorthLink WA project at Muchea;
  • New local access roads to provide safer access points to the highway; and
  • Improved road geometry and grades.

Once the upgrade works are complete, the existing portion of Great Northern Highway will become a local access road, providing greater separation for local and regional traffic.
