HC Deb 05 November 1969 vol 790 c152W
Mr. John Page

asked the Minister of Transport what steps he is taking to clear loose chippings from the M4 motorway and its verges particularly between the Slough Central and Feltham junctions which have resulted in many smashed windscreens with dangerous consequences during the last few weeks.

Mr. Bob Brown

The hard shoulders are swept every 3 or 4 days. The speed and density of traffic is such that loose chippings quickly reach the shoulders and, consequently, sweeping the traffic lanes is rarely necessary. The agent authorities responsible for maintenance of the road keep a close and continuing watch on conditions and can be relied upon to take any action which may be required.
