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