§ Mr. Sillarsasked the Secretary of State for the Environment what is the current cost of lighting 20 miles of motorway.
§ Mr. CarmichaelThe cost of lighting motorways varies considerably. It depends on many factors—for example, whether it is on a motorway under construction or one open to traffic; the widths of the carriageways; the frequency and complexity of interchanges; the mode and type of lighting used; accessibility to electricity supplies and whether there is a need to provide or modify safety fences.
The cost per mile for conventional column central reserve mounted lighting could range from about £20,000 to £60,000.
