§ Mr. Skeetasked the Secretary of State for Transport, on the basis that the cost of renewing one mile of single track railway costs £92,500 at July 1977 prices, what are the comparative figures for one mile of roadway with a tarmacadam surface and of a dual carriageway similarly surfaced.
§ Mr. William RodgersThe estimated cost of renewing a mile of single carriageway road varies between £65,000 and £140,000 at 1977 prices, depending on the strength provided, and is approximately twice the latter figure for dual carriageways.
