§ Mr. Gwynfor Evansasked the Secretary of State for Wales what mileage of class one or principal roads in Wales is below the minimum width recommended by his Department; and what percentage this is of their total mileage.
§ Mr. Cledwyn HughesThere is no minimum width for principal roads. For new or improved roads there are standards related to the volumes of traffic expected to be carried. The extent to which existing principal roads are below these standards depends also on traffic volumes82W and is a matter for the local highway authorities.
§ Mr. Gwynfor Evansasked the Secretary of State for Wales what proportion of trunk roads in Wales is over-loaded according to the standards of his Department.
§ Mr. Cledwyn HughesOut of 1,003 miles of trunk road in Wales, 295 miles or about 29 per cent. are overloaded. Taking the more critical factors into account this does not necessarily mean that there is serious congestion on the lengths concerned.
§ Mr. Gwynfor Evansasked the Secretary of State for Wales if he will state the average width of trunk roads in Wales in 1962 and 1967 respectively.
§ Mr. Cledwyn HughesA sample survey conducted by the Road Research Laboratory in 1958 indicated that the average carriageway width of trunk roads in Wales was then 22 feet. No figure is available for 1962 but a further sample survey is now being conducted and the results will be made known in due course.
