Nambucca Heads to Urunga - Pacific Highway upgrade

Roads and Maritime Services has completed the 22 kilometre highway upgrade from Nambucca Heads to Urunga. The project included building two new interchanges at Nambucca Heads and Ballards Road and upgraded the existing Waterfall Way interchange at Raleigh. The $780 million project was jointly funded by the Australian and NSW governments. The project opened to traffic on 22 July 2016.

Updates and announcements

Pacific Highway Pavement Grinding Trial at Valla

Roads and Maritime Services will begin a pavement grinding trial on sections of the Pacific Highway in the Valla area in June 2018. The trial is a detailed investigation of pavement grinding, which has been shown to reduce road surface noise under certain conditions.

The trial will be done on two separate sections of the Pacific Highway near Valla Beach, totalling about six kilometres, and will take about 12 weeks.

Road side noise measurements and a community survey will form part of the trial. A report will be prepared at the conclusion of the trial. Further information can be found in the June 2018 project notification (PDF, 40Kb).

Further information about the trial can be found in our Frequently Asked Questions

Post-construction Operational Noise Report

The Post-construction Operational Noise Report for Nambucca Heads to Urunga Pacific Highway upgrade is now available.

The assessment found the noise levels on the project are generally lower than what was predicted in the noise model. The report shows that the project has met its noise goals as required by the Minister’s Conditions of Approval for the upgrade. Consequently, no further noise mitigation measures are required. Please see the frequently asked questions (PDF, 194Kb) and notification (PDF, 77Kb) for further information about operational noise.

Project background

Roads and Maritime Services engaged Lend Lease to design and build the Nambucca Heads to Urunga upgrade. Major work began on 15 January 2014 and was completed in July 2016.

Operational noise monitoring and reporting

Roads and Maritime Services engaged AECOM to carry out the post-construction operational noise assessment. The purpose of this assessment is to compare actual noise levels against the predicted noise levels used in the project design, and examine the mitigation measures currently in place to determine if further mitigation measures are required.

The noise report has now been reviewed by NSW Environment Protection Authority (EPA) and Department of Planning and Environment (DP&E) to ensure regulatory requirements have been met and is now available to the public.

Noise monitoring was carried out during November and December 2016 at various locations throughout the project.

Noise goals for individual properties are determined through the NSW Environment Protection Authority’s Environmental Criteria for Road Traffic Noise (ECTRN) and take into account whether the upgrade is on a completely new alignment or is the redevelopment of the existing highway. The Environmental Noise Management Manual (ENMM) sets the criteria for noise mitigation measures, such as architectural treatments in houses, when the noise goal is exceeded.

The measured results of the noise report are within a close correlation with the predicted noise levels across all locations on the project and meet the Environmental Criteria for Road Traffic Noise (ECRTN) for assessing operational traffic noise levels for new freeways.  No further mitigation measures are proposed on the project.

Our frequently asked questions and notification provide further information about operational noise. The fact sheet about managing traffic noise for new and upgraded roads is also available.
