HC Deb 16 March 1960 vol 619 c97W
37. Mr. Grimond

asked the Minister of Transport if he has given further consideration to the provision of extra road space either by using abandoned railway lines or covering over existing lines.

Mr. Marples

There are at present six road schemes which involve the use of abandoned railway lines and one where it is proposed to build on viaduct over a railway line in operation. I shall continue to approve such schemes where they are justified on economic and engineering grounds.
