Changes to Transport Noise Corridor (TNC) effective 29 January 2020

Changes to the Transport Noise Corridor (TNC) occurred on January 29th 2020 for all State-controlled roads and rail networks.

The updated changes consist of the following:

• State-controlled road corridors
– now take buildings and other barriers into consideration, which may have reduced the noise category within some built up areas;

• State-controlled rail corridors
– in addition to taking buildings and other barriers into consideration, some rail TNC’s have been extended from 100m to 250m either side of the rail line.

Note that the updated mapping now supersedes all previous mapping.
