§ Mr. Jessel
asked the Secretary of State for the Environment what effect he expects the completion of the Greater London Council's new road to replace the A305 to have upon the number of vehicles using nearby stretches of the A316 and the M3; and when he now expects the new GLC road to be open to traffic.
§ Mr. Carmichael
Two-way daily traffic flows on the M3 motorway west of the Sunbury interchange were recently recorded as 18,600 vehicles per 16-hour day. I understand that two lanes of the western part of the elevated section of the GLC's A305 improvement have been opened to-602W day and that the whole scheme is scheduled for completion by the end of 1975. After today's opening an additional 900 vehicles per day are expected to use the M3. On completion of the GLC works there may be a further increase of about 1,500 vehicles per day.
A forecast of the effect of the completion of the A305 on traffic flows on the western section of the A316 is not available. Much will depend on the driver's choice of route on leaving the motorway and the effects of management measures and road works carried out by the GLC on the remainder of the A316 through Richmond and Chiswick.
