HC Deb 20 February 1990 vol 167 c607W
Mr. Steinberg

To ask the Secretary of State for Transport what is the current cost per mile of motorway construction.

Mr. Atkins

Costs vary so much—because of differences in factors such as the location of the road, the number and design of junctions and structures, and ground conditions—that it is impractical to give an average cost per mile. Recent examples of works costs per mile of motorway schemes are, in outturn prices:

£ million
New motorway
M40 Warwick North 4.2
M40 Warwick South 4.8
M63/M66 Portwood-Denton 10.0
M25 Junctions 11–13 4.5
M63 Stages 1 and 2 (with Barton Bridge) 12.0
