§ Dr. Marekasked the Secretary of State for Transport what are the projected night-time traffic loads on the various sections of the M25 yet to be opened.
§ Mrs. ChalkerThe estimated figures are as follows:
Section No. of vehicles between 10pm and 6 am Swanley-Sevenoaks, Kent 3,000–4,000 Swanley Links, Kent Leatherhead-Reigate, Surrey 2,500–3,500 Leatherhead Interchange, Surrey Wisley-Leatherhead, Surrey Airport Spur to M4, Surrey/Buckinghamshire 4,500.5,500 M4–M40, Buckinghamshire 4,000–5,000 M40 Interchange, Buckinghamshire M40-Maple Cross, Buckinghamshire/Hertfordshire Micklefield Green-South Mimms (A405–M1), Hertfordshire 3,000–4,000 Micklefield Green-South Mimms (M1–A1(M)), Hertfordshire 2,000–3,500 A19–M11, Hertfordshire/Essex 3,000–4,000 The above figures assume that all sections of M25 are in full use and represent average daily flows for a "neutral" month in 1987. Flows will be somewhat higher during the summer months and lower during winter; similarly vehicle usage tends to be greater at weekends than during the week —Monday to Friday.
