HC Deb 19 December 1974 vol 883 c606W
Mr. Geoffrey Finsberg

asked the Secretary of State for the Environment what is the cost of constructing one mile of three-lane motorway in the urban areas.

Mr. Carmichael

Construction costs for motorways in urban areas differ widely, and are unique to each individual scheme, depending on the location and type of construction necessary—viaducts, underpasses, etc. I will write to the hon. Member when further information is obtained.
