§ Mrs. Dunwoody
To ask the Secretary of State for Transport if he will list the average construction cost per mile of the electrification of railways together with rate of construction per mile of new roads built since 1980. 
§ Mr. Watts
The information is not available in the form requested. However, the cost of upgrading the east coast main line, including electrification, was around £360 million at current prices, equal to around £1 million per mile.
Information on the construction cost per mile of new roads is available only since 1989–90. For the period 1989–90 to 1995–96, the average construction cost per mile of all-purpose dual carriageway trunk roads was around £6 million and the average construction cost per mile of motorways was around £14 million, both at current prices. These figures exclude design fees, VAT, land and other compensation costs, site supervision and contractual claims.
