HC Deb 06 April 1971 vol 815 c120W
Sir Clive Bossom

asked the Secretary of State for Wales how many miles of dual two-lane motorways are in use in Wales, and how many miles thereof were constructed in a way which provided for widening to three-lane carriageways at a later date.

Mr. Peter Thomas

Twenty-three miles are in use. No provision has been incorporated for future widening. The present motorway programme provides for the building of three-lane carriageways wherever it is appropriate.
