§ 10. Mr. RobathanTo ask the Secretary of State for Transport what assessment he has made of the effectiveness of acoustic barriers on the M1 near Junction 21. [179619]
§ Mr. JamiesonA recent report into noise from this section of motorway confirmed that noise levels could be reduced by the installation of acoustic barriers. However, the carriageway here is nearing the time when it needs to be resurfaced and the Highways Agency considers that the use of lower noise surfacing would provide a sufficient reduction in noise levels in this location.
