We have reviewed our existing noise maps and decided which ones need to be revised in 2017.

The Environmental Noise Directive requires strategic noise maps to be reviewed, and revised if necessary, at least every five years after the date of their preparation. In 2017 we produced new noise maps for major roads across Wales, and for industry in our largest towns and cities.

You can see the noise maps on our Wales Noise Mapping website (external link).
