HC Deb 23 December 1981 vol 15 c459W
24. Mr. Cyril D. Townsend

asked the Secretary of State for Transport if he will estimate the likely cost of one year's delay in completing the M25.

Mr. Kenneth Clarke

If the sections not already under construction were each delayed by a year the extra costs of travel and accidents would be some £20 million or more, and many thousands of people in outer London would face a further year's noise, disturbance and danger. For that reason, we are doing all we can to maintain progress.
