§ Mr. Ronald Atkins
asked the Secretary of State for the Environment what is the average cost of a mile of motorway.
§ Mr. Wigley
asked the Secretary of State for the Environment what is the average cost per mile of building motorways at current cost levels, based on average agricultural land values; and what proportion of this cost is in the first instance the cost of direct labour involved in this construction work.
§ Dr. Gilbert
The construction costs vary widely depending on the nature of the terrain through which the motorway passes. On rural motorway schemes, for which contracts were let between 1st January 1972 and 31st December 1974, costs at June 1976 prices were in the range of £0.93 million to £4.73 million per mile for dual three-lane motorways,516W
