Project Description

The $175 million NorthLink Western Australia (WA) Stage 3 project involves the design and construction of approximately 26 kilometres of new dual carriageway highway between Ellenbrook and Muchea, in the North East of Perth.

This project is the third stage of the overall $1.12 billion NorthLink WA project, which also included upgrades to the Tonkin Highway to complete a free flowing state-of-the-art transport link connecting Great Northern Highway and regional areas, with Malaga, Kewdale and Perth Airport.

Construction work on Stage Three started in 2017 and finished in 2019.
