The $247 million Holbrook bypass opened to traffic on Wednesday 7 August 2013.

Project background

The project was funded by the Australian and NSW governments.

The 9km bypass was built to the west of Holbrook to improve safety and transport efficiency. It runs from 4km north of Holbrook where deviates west from the existing dual carriageways to cross Wagga Wagga Road.

The bypass crosses the former Town Common area, passing to the west of the cemetery, sewerage treatment works and industrial area and then across Culcairn Road.

From Culcairn Road the bypass crosses Ten Mile Creek and rejoins the existing dual carriageway two kilometres south of Holbrook.

The Holbrook bypass was designed by Roads and Maritime Services and constructed by Abigroup.
