HC Deb 31 January 1973 vol 849 c393W
Mr. Kinsey

asked the Secretary of State for the Environment when the second experimental sound barrier will he erected on the Perry Barr section of the M1-M6 linkway.

Mr. Speed

Work on the erection of an additional 1 kilometre length of experimental sound barrier along the south side of the motorway will start on 1st February and should be completed by mid-April. It is hoped that work on Phase III—erection of wooden barriers on the bridge parapets over Queslett Road—will proceed concurrently.
