HC Deb 09 July 1986 vol 101 c212W
Mr. Nicholas Winterton

asked the Secretary of State for Transport if he will estimate the total cost of increasing the size of the M25 motorway to four lanes in either direction.

Mr. Peter Bottomley

Widening the whole motorway would be costly and disruptive. No estimate has been made. There is no evidence at present that it is likely to be necessary.
