§ 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.
