The busy section of Great Northern Highway (GNH) from Muchea to Chittering Roadhouse will be upgraded. A dual carriageway will be provided for the first 3.5 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.
The contract to deliver this work has been awarded to WBHO Infrastructure Pty Ltd. Early works have commenced and road users are reminded to take care when driving through the project site. Traffic management including speed restrictions and lane closures will be in place when required.
Scope of works
- Construction of 3.5 kilometres of dual carriageway (linking up with the NorthLink WA project at Muchea) and 8.5 kilometres 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
