§ Mr. Dudley Smithasked the Secretary of State for Transport how many miles 181W of motorway in England and Wales remain unlighted; what percentage this is of the total motorway complex; and what it would cost to light the unlighted sections.
§ Mr. HoramAbout 1,050 miles or 80 per cent. of the total motorway mileage of about 1,316 miles in England and Wales remain unlighted.
It costs between £25,000 to £75,000 per mile to light motorways that are open to traffic, depending on the frequency and complexity of interchanges, the availability of electrical supplies and the safety fence alterations required. It is not possible to prepare an estimate of the cost of lighting the unlighted sections without making a detailed survey of each.
