HC Deb 28 February 1980 vol 979 c739W
Mr. Neil Thorne

asked the Minister of Transport what contribution is being given to increasing the capacity and improving the safety of the M4 between Chiswick and Heathrow airport where there is at present provision for only two lanes of traffic, and no emergency hard shoulder.

Mr. Kenneth Clarke

I have no plans to increase the capacity. A contract has been let to strengthen the parapets adjacent to the two-lane section.
