HC Deb 18 April 1973 vol 855 c118W
Mr. Edwin Wainwright

asked the Secretary of State for the Environment how many miles of crash barriers on the central reservations have now been erected on the Ml motorway; what is the additional mileage to be built by the end of 1973; and what is the date when it is expected that the full length of this motorway will have crash barriers.

Mr. Peyton

Approximately 70 miles. A further 75 miles is anticipated by a year from now, so completing the London-Sheffield length.
