HC Deb 03 May 1972 vol 836 c153W
Mr. Spearing

asked the Secretary of State for the Environment when he expects to publish the results of the investigations of the Road Research Laboratory into the effects of heavy vehicles on underground services and foundations of buildings.

Mr. Graham Page:

With regard to the effect of vehicles on underground services there is nothing I can add to my reply of 1st May to the hon. Member. A report by the Transport and Road Research Laboratory on a survey of traffic-induced vibrations (LR 418) was published in November, 1971.—[Vol. 835, c. 31.]
