NorthLink WA
Project Details
The Australian Government has committed $894.34 million to the NorthLink WA project, which
comprises the Swan Valley Bypass and the Tonkin Highway grade separations projects.

interchanges on the highway at Morley Drive and Collier Road, and a flyover at Benara Road. The
Australian Government is providing $224.96 million to this project, comprising $140.6 million through
the Infrastructure Investment Programme and $84.36 million as part of the $499 million additional

Benefits
The Great Northern Highway forms a key freight route connecting Perth to the north of Western Australia,
and is an important link for the transport of equipment and supplies to mining operations in the Pilbara
region. The existing section of the Great Northern Highway through the Swan Valley is experiencing strong
traffic growth, and the mix of heavy vehicles with light residential and tourist traffic is leading to traffic
congestion and reduced safety and amenity.

The NorthLink WA project is expected to improve freight efficiency and freight network capacity, reduce
vehicle operating costs and provide travel time savings. It will also relieve traffic congestion and improve
the safety of the existing highway through the Swan Valley.
Together, the two components of NorthLink WA will provide a continuous connection from the Perth Airport
area to Muchea and, together with the Gateway WA and Perth Freight Link projects, will form part of a high
standard freight connection through the Perth urban area to Fremantle Port.
