§ 53. Sir Clive Bossomasked the Secretary of State for the Environment what is the mileage of new motorways on which it is not intended to install crash barriers before the motorways are opened, the additional cost which would have to be incurred to provide the barriers before the motorways are opened, and the estimated 358W cost of providing the barriers at later dates.
§ Mr. Graham PageWithin the programme of 1,000 miles of motorway barrier by 1975, about 100 miles of new motorway will not be provided with barriers before opening. The cost of installing barriers prior to opening would have been approximately £13,000 per mile. The estimated cost of providing barriers at later dates is expected to be about £11,000 per mile.
