Helping Increase the Road Network in Australia

Recognised as a project of national importance by the Australian Government, the Hunter Expressway project represents an investment of $1.7 billion.


The project includes the construction of a new 40 km dual carriageway connecting the F3 Freeway to the New England Highway west of Branxton.


Comprising NSW Roads and Maritime Services, Thiess, WSP and Hyder Consulting, the Hunter Expressway Alliance was formed to design and build the 13 km eastern section of the Hunter Expressway from the Newcastle interchange on the F3 Freeway.


Our section of the four-lane expressway included interchanges located at the F3 Freeway and Buchanan, 840 m of viaduct including three bridges, bridges at many other locations and the treatment of extensive disused underground mine workings.
