§ 60. Mr. Cooper
asked the Minister of Transport what steps he proposes to take both to reduce the size and numbers of traffic roundabouts and to substitute these wherever practical with flyovers.
§ Mr. Marples
It is not in general desirable to reduce the size of roundabouts because the traffic capacity of a roundabout is usually proportionate to its size As regards the numbers, it is my intention to provide flyovers in substitution for roundabouts at major traffic108W intersections where this is practicable and the volume of traffic is such as to justify the additional cost. Some roundabouts will, however, continue to be built where they offer the most suitable form of junction. In appropriate cases new roundabouts are so designed as to permit the conversion to a grade separated junction should this become necessary later.
