Woomargama Bypass

The 9km bypass to the west of Woomargama, joining the existing Hume Highway divided carriageways to the north and south of the village, opened in 2011.


About the project

The $265 million Woomargama bypass was opened on Monday 7 November 2011.

The Hume Highway Woomargama Alliance designed and constructed the Woomargama bypass. The alliance team comprised Roads and Maritime Services (replacing Roads and Traffic Authority), Abigroup and Sinclair Knight Merz.

The project was funded by the Australian Government.

The Woomargama bypass runs from 8km south of Holbrook where it deviates from the existing dual carriageways before crossing Sandy Creek and passing to the west of Mount McKenzie.

The bypass crosses Mountain Creek and rejoins the recently completed Hume Highway duplication south of Fairburn Road.
