Mr. Alan Williamsasked the Secretary of State for Wales on what evidence it was decided that a Cardiff by-pass is not necessary; if he will publish this information in the Official Report; on what date, and by whom, this evidence was collected; what were the precise locations of the points of inquiry, and over what period the inquiry took place; whether information was collected of traffic travelling through Cardiff to the North as well as to the West, and what evidence was sought of traffic taking detours around Cardiff in order to reach destinations in the North and West.
§ Mr. Cledwyn HughesI have not decided that an outer by-pass is unnecessary. I am still considering its traffic and economic justification, including the possible effect of extensive development in the Llantrisant area. A traffic survey was undertaken by the Cardiff City Council in 1963 and reassessed in connection with the Buchanan study. It showed that, of the traffic which would 89W be likely to use Eastern Avenue, only about 10 per cent. might be expected to transfer to an outer by-pass. The survey covered external zones, including zones to the north of Cardiff, as well as the central area of the city.
