HC Deb 01 August 1951 vol 491 c210W
Mr. Vane

asked the Minister of Transport what is the approximate cost per mile of constructing a roadway built over existing railway lines wide enough to carry two and three lines of traffic. respectively.

Mr. Barnes

The cost would depend upon the circumstances of each particular case and there is no reliable basis upon which I could give a general estimate of the kind the hon. Member has in mind.
