I am grateful for what my hon. Friend said at the beginning of his remarks. With regard to his specific question about four lanes for the M1 and the M25, I shall shortly place a contract for the addition of a fourth lane between junctions 11 and 13 of the M25. I am considering a similar study of another heavily used section between junctions 15 and 16. Just before Christmas I announced a review of the pattern of traffic on the M25 to see whether the capacity of other sections needs to be increased.
On the M1 we are adding some short stretches of climbing lane. I do not think that at this stage it is necessary to have additional lanes because, as the House knows, before long the M40 will be completed between London and Birmingham, and I expect it to carry a substantial part of the traffic.
