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

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.

Community drop-in sessions

You are invited to attend a community drop-in session to discuss the Post-construction Operational Noise Report. There is no formal presentation, however the sessions will provide an opportunity to meet with the project team and ask questions about the report.

Details for the sessions are:

  • When: Tuesday 1 August 2017, from 4-7pm
  • Where: Senior Citizens Hall, Bowra Street, Urunga.

  • When: Wednesday 2 August 2017, from 4-7pm
  • Where: Nambucca Community and Arts Centre, Ridge Street, Nambucca Heads.

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.
