Noise barriers

As part of the Gateway Upgrade North project, a detailed road traffic noise assessment has been completed to ensure noise is managed appropriately into the future. The assessment was carried out in accordance with the Department of Transport and Main Roads’ Transport Noise Management: Code of Practice – November 2013. The Code of Practice establishes a standard process for dealing with the effects of road traffic noise.

The noise assessment involved noise monitoring at various properties across the project alignment to develop a noise model. This model predicts future noise levels and the need for treatments, such as noise barriers.

The model considers and incorporates existing and future traffic volumes and speed, road gradient and road surface, height and location of residential dwellings and other buildings, and the noise reducing effects of natural and constructed noise attenuation.
