HC Deb 04 March 1982 vol 19 c232W
Mr. Anthony Grant

asked the Secretary of State for Transport if he will estimate the reduction in traffic on principal through roads in the London borough of Harrow as a result of completion of the M25; and when he now expects the M25 to be completed.

Mr. Kenneth Clarke

I expect that the reduction in traffic could be of the order of 10 per cent. 1986 is the expected year for completion.
