§ Mr. Fryasked the Minister of Transport, following his Department's decision to modify the declared design standards set out in technical memorandum H6/74 for the proposed M4-M40 section of the M25, whether he will issue an amended version of the memorandum or state in exactly what circumstances roads schemes need not comply with the established standards.
§ Mr. Kenneth ClarkeTechnical memorandum H6/74 is kept under routine review but, as my right hon. Friend explained in his policy statement on 27 July, when design proposals are determined in a situation of uncertain traffic forecasts, account is taken of the risks of making a wrong decision. Each case is considered on its merits and the best design standards are in the end a matter of judgment on all the available data for each project.
