HC Deb 22 July 1974 vol 877 cc382-4W
Mr. Jessel

asked the Secretary of State for the Environment (1) what is his estimate of the daily vehicular traffic (a) prior to the opening of the M3 on 11th July, (b) currently since the M3 opening but before the opening of the GLC link road from the M3 to the A316 at Hanworth), and (c) forecast figures after the completion of the GLC link road, on the following roads in the Twickenham constituency: 1, Great Chertsey Road (A316) at Hospital Bridge Road roundabout; 2, Great Chertsey Road (A316) at St. Margaret's roundabout; 3, Hanworth Road; 4, Hospital Bridge Road; 5, Uxbridge Road, Hampton Hill; 6, Park Road, Hampton Hill; 7, Upper Sunbury Road; 8, Hampton Court Road; and 9, Staines Road;

(2) what percentages of traffic emerging from the M3 at Sunbury he expects to head for (1) Twickenham Bridge, (2) Kingston Bridge, (3) Hampton Court Bridge, (4) destinations within the Twickenham constituency, and (5) other destinations to the west and north of Twickenham; (a) currently, pending completion of the GLC link road from M3 to A316; and (b) after completion of the GLC link road respectively;

(3) how many vehicles per day, and per hour at peak hours, he expects to enter and leave the M3 motorway at Sunbury on an average day in the second week after the opening on 11th July and what he expects the corresponding figures to be in the second week after the completion of the GLC's link road between the M3 at Sunbury and the Hope and Anchor roundabout Hanworth.

Mr. Carmichael

The information is not available in the form asked for.

I would refer the hon. Member to my answer to the hon. Member for Brentford and Isleworth (Mr. Hayhoe) on 28th June 1974—[Vol. 875, c. 557–8.]—for estimated traffic flows on the M3 at Sunbury and on the Great Chertsey Road (A316). It is impossible to predict with accuracy the routes which drivers select, but the best estimates available about the roads in question other than the A316 suggest that there is unlikely to be any significant increase in traffic as a result of opening the M3. There is no detailed information available about drivers' destinations on leaving the M3. It is estimated, however, that about 85 per cent. of the traffic will continue along the A305 while the balance will be equally split between Staines Road East and Staines Road West (A308). On completion of the Greater London Council's works on the A305 the volume of traffic using the M3 and A305 may increase slightly in peak hours.
