HC Deb 10 April 1967 vol 744 c147W
Mr. Alan Williams

asked the Minister of Transport what has been the average acreage of land required per mile of motorway constructed.

Mr. John Morris

For a mile of six-lane motorway about 24 acres, inclusive of junctions. The figure has been greater where long or high embankments or cuttings were needed. This will be reduced to about 22½ acres per mile under the revised design standard recently announced.
