HC Deb 06 May 1969 vol 783 c76W
Mr. Crawshaw

asked the Minister of Transport what are his conclusions as to the relative skid resistance between the blacktop and concrete sections of motorways as a result of the recent report, LR 245, made to his Department.

Mr. Marsh

It would be inappropriate for me to draw general conclusions on the relative skid resistance of motorways of different forms of construction from a report on the condition of M4 West of London, the most densely trafficked motorway in Europe.
