§ Mr. Dudley Smithasked the Minister of Transport if he will state the approximate date for the completion of the M.4 motorway as it affects the Borough of Brentford and Chiswick; and when he expects the full, completed motorway to be ready for public use.
§ Mr. MarplesWe expect to complete the viaduct section of the M.4 from Chiswick Flyover to Boston Manor Park in December, 1964, and the length from Boston Manor Park to Langley early in 1965.
The Slough and Maidenhead By-passes are already open to traffic. The Newport By-pass should be ready towards the end of 1965 and Severn Bridge in the following year.
We hope to start work on the Almondsbury-Hambrook section in Gloucestershire later this year. The Hambrook-Tormarton and Newport-Crick sections are still going through the statutory processes.
Between Maidenhead and the Gloucestershire boundary my consulting engineers are still carrying out surveys. As soon as possible after receiving and studying their report I will publish a draft Scheme under Section 11 of the Highways Act, 1959, setting out the proposed line of route. This is unlikely to be before the end of 1963. It is too early to say when the whole of the M.4 will be open to traffic.
