HC Deb 12 July 1990 vol 176 c279W
Mrs. Margaret Ewing

To ask the Secretary of State for Transport what estimates he has of the increased volume of traffic flow resulting from the upgrading of the Al-M1 route to motorway standard.

Mr. Atkins

The existing A1 trunk road traffic is expected to use the upgraded road. We also estimate that there would be a small transfer of traffic from the M1 to the upgraded Al. General growth in traffic is estimated in the national road traffic forecast 1989.
