§ Mr. Sillarsasked the Secretary of State for Scotland what is his estimate, at 1977 prices, of the cost of an average mile of motorway and dual carriageway construction, respectively.
§ Mr. McElhoneA meaningful average cannot be obtained. Construction costs vary widely, depending on the terrain and the nature of the scheme.
§ Mr. Sillarsasked the Secretary of State for Scotland what is his estimate at current prices of creating a motorway between Glasgow and Carlisle on the line of the present A74/M74.
§ Mr. McElhoneNo recent estimate is available. In 1976 it was considered that the conversion of the A74 to motorway standard would cost well over £100 million.
§ Mr. Sillarsasked the Secretary of State for Scotland (1) what is his estimate at current prices of making the A75 a full dual carriageway between Stranraer and Dumfries;
(2) what is his estimate at current prices of making the A77 from Ayr to Stranraer a full dual carriageway with bypasses round both Maybole and Girvan.
§ Mr. McElhoneNo estimate can be provided for these works as there are at present no plans for undertaking them.
§ Mr. Sillarsasked the Secretary of State for Scotland what is his estimate of the cost involved in constructing bypasses on the A77 serving Maybole and Girvan.
