I have lobbied in writing, by attending the consultation with officials, and by talking to Ministers and officials to get better abatement of M4 noise as we move to a smart motorway.
I am pleased to report that following further conversations the Highway Agency says it is now planning to provide noise reducing surface materials for all lanes of the motorway. I am still in discussion with them over their current plans for additional barriers, as I wish to see residential areas offered additional protection from these where possible and helpful.
