§ 21. Captain McEWEN(for Mr. LESLIE BOYCE) asked the Minister of Transport the estimated life of the great trunk roads from the date of the completion of their construction?
§ Mr. PYBUSExcavation, foundation and surfacing material obviously have varying lives, but my hon. Friend may be interested to know that for loan repayment purposes the three are generally equated to 20 years. There is, however, no special period for trunk as opposed to other roads.
