Mr. Cran
To ask the Secretary of State for Transport what is the estimated current daily traffic flow on the M1; and what were the comparable figures (a) 10 years ago, and (b) expected when the motorway was built.
Mr. Peter Bottomley
The table sets out estimated daily traffic flows, currently and 10 years ago, for those stretches of the M1 for which such information is available. Information on the traffic flows expected at the time of opening is not available except at disproportionate cost. The figures are annual average daily traffic flows unless otherwise stated.
