The Hunter Expressway

The Hunter Expressway project overview

The 40 kilometre, four-lane Hunter Expressway is being constructed under two contracts. 

Eastern Section: F3 to Kurri Kurri

The Hunter Expressway Alliance (Roads and Maritime Services, Thiess Pty Ltd, Parsons Brinckerhoff and Hyder Consulting) started construction on this 13 kilometre section of the project in August 2010.

The eastern section includes two grade-separated interchanges - at the F3 Freeway and at Buchanan, as well as overbridges at Seahampton Road and Averys Lane. Rest areas for light and heavy vehicles will be built on both sides of the expressway at Buchanan.

Three high bridges (or viaducts) will span the steep gullies through the Sugarloaf Range and are located 1.4 to 2.7 kilometres west of the F3 Freeway. The viaducts have a total length of 787 metres and are up to 47 metres in height above the gully floors. This website has a video that explains how the high bridges are being built and it is available on the video library page.

Western section

Abigroup Contractors Pty Ltd started construction on the 27 kilometre western section of the project in April 2011 (design and construct contract).

In the western section of the project, construction is progressing well and significant work is visible to passing motorists.

The western section includes four grade-separated interchanges – at Kurri Kurri, Loxford, Allandale and Branxton. It also includes road bridge crossings at McLeod Road at Loxford, Old Maitland Road at Sawyers Gully, Camp Road at Allandale and Tuckers Lane at Greta.

Bridge construction is continuing at various locations between Kurri Kurri and Branxton. Major earthworks are progressing well, and by January 2012 more than 1.6 million cubic metres of soil had been moved. Abigroup has approximately 3 million cubic metres of earthworks as part of its construction.


The Australian Government is funding $1.5 billion and the NSW Government up to $200 million to complete the project.


The Hunter Expressway opened to traffic on 22 March 2014.
