Mrs. Chalker

The information requested is as follows:

  1. (a) £3 million.
  2. (b) £5 million.
  3. (c) £7 million.
  4. (d) £10 million.
  5. (e) £3 million.
  6. (f) No figures available.
  7. (g) £1 million.

All figures are at current prices and cover works only. Costs of land, rehousing, preparation and supervision and so on add between 20 and 25 per cent. to total costs. The figures given are averages. Construction costs of motorways and trunk roads vary widely depending in particular on the nature of the terrain through which the road passes.
