§ Mr. Edwin Wainwrightasked the Secretary of State for the Environment how many miles of the M1 motorway between London and the M6 take-off now have lighting installed; and how many accidents have occurred in the miles of motorway which are lighted and not lighted, respectively, over each of the past six years.
§ Mr. MarksTo date, about 36 miles of road lighting has been installed on this length of the M1, between Junction 2 (Fiveways) and Junction 19 (Catthorpe). The following table gives the lengths of motorway lit and unlit on MI between those two junctions for the years 1970–1975, together with the requested accident data:
with a mean of £2.10 million per mile, and in the range of £1.06 million to £2.04 million per mile for dual two-lane motorways with a mean of £1.44 million per mile.
Costs of land acquisition and rehousing are excluded from these figures. These costs also vary widely and can account for 10 per cent. of the overall costs of rural schemes. Land acquisition costs and construction costs will, of course, be considerably higher for urban schemes than for rural schemes. Figures for the mean cost per mile of urban motorways would not be very informative because of the wide variation in costs.
Labour costs are generally approximately 25 per cent. of the construction cost.
