HC Deb 21 June 1971 vol 819 c212W
Mr. Wiggin

asked the Secretary of State for the Environment what time limit was set by his Department on the construction of the barriers on the M4; and to what extent economies to the motoring public were considered before deciding not to work at night and weekends.

Mr. Michael Heseltine

The time limit for the construction of barriers on the M4 from London to Bray Interchange is mid October, 1971 and the contractor is ahead of schedule. From the Bray interchange to Holyport the time limit is 31st March, 1972. The programme for the installation of barriers on the remainder of the M4 is set out in the detailed Safety Barrier programme announced by my hon. Friend on 16th December, 1970 (Vol. 808 c.353-4), as amended.

The installation of the barriers from Airport Spur to Bray is a part of the contract for the widening of the M4 from two to three lanes between Langley and Holyport which necessarily had to inconvenience daytime traffic.
