The busy 13 km section of Great Northern Highway (GNH) from Muchea to Chittering Roadhouse will be upgraded. A dual carriageway will be provided for the first three kilometres north of the planned NorthLink interchange at Muchea. The balance of the project will be constructed as a single carriageway. Sufficient land has been acquired adjacent to the highway to allow for the future development of a dual carriageway to Chittering Roadhouse.
Scope of works
- Construction of three kilometres of dual carriageway (linking up with the proposed NorthLink WA project at Muchea) and 10 km of new wider single carriageway through to Chittering Roadhouse. The new highway will be built next to the existing GNH
- Realignment of intersections at Old Gingin Road, Reserve Road, Wandena Road, Maddern South Road and Sugar Gum Drive
- The existing highway will be used as local access roads to avoid future congestion and provide safer access points to the highway
