Nambucca Heads to Urunga Pacific Highway Upgrade
Project Overview
Client: Roads & Maritime Services
Length: 22 km
Duration: February 2013 to July 2016
Value: $780 million

Works undertaken
The Nambucca to Urunga highway project involved the construction of approximately 22 kilometres of four-lane divided road, built to Class-M (motorway) standards. This stretch extends from south of the North Coast rail overbridge at Nambucca Heads to the existing interchange with Waterfall Way at Raleigh. The upgrade enhances connectivity and traffic flow with the introduction of new grade-separated interchanges and significant infrastructure improvements.
