Mr. Peter Walsh:

I think it is fair to say there is not one. We are conscious of noise being a matter of concern. We receive quite a bit of correspondence from a number of parts of the country, not least the M50 and M11. Noise mapping is something we have undertaken. The information has been made available to the local authorities, which are required to draft plans around how to deal with it. I am not aware of having received any output from those plans. We do not have a programme for retrofitting. I cannot, therefore, really offer any kind of comfort in terms of the manner in which we as a country are engaging with the implications of noise or how to mitigate it. We do have noise barriers as part of projects.
