HC Deb 23 January 1975 vol 884 c491W
Mr. Gow

asked the Secretary of State for the Environment what is the total length of motorway at present in use; how many miles of those motorways have a central crash barrier; and what is the policy of the Government in regard to the installation of central crash barriers on motorways where they do not exist at present.

Mr. Carmichael

There are 1,065 miles of trunk road motorway in England; about 930 now have a central barrier.

Central barriers are now being provided on all busy motorways; provision on less busy motorways will be kept under review.
