New Grafton bridge : post-construction operational noise report

The Clarence River Bridge Crossing project in Grafton involved the construction of a new bridge crossing over the Clarence River in Grafton to improve traffic flow for the areas to the south and north of the river, with the existing bridge being retained to provide a crossing for local traffic. Key features of the new Clarence River Crossing (new Grafton bridge) project include a new 525-metre long bridge, 70 metres downstream from the existing road and rail bridge, to provide a second crossing of the Clarence River. The new bridge connects to the existing road network in Grafton and South Grafton. Construction of the project started in November 2016, and it was opened to traffic in December 2019. During the pre-construction phase of the project, predictive noise modelling was carried out to determine the likely road traffic noise levels expected from the project. The results of the noise modelling for the project were presented in the detailed noise modelling and assessment report (ref. TJ502-01F07 (r7) Noise Modelling & Assessment, dated 29 March 2018).
