To ask the Secretary of State for Scotland if he will list the locations and duration of temporary traffic light controls on the Scottish section of the A1 trunk road during the last year, giving the reason for each case.

Temporary traffic light controls on the A1 in Scotland (approximately 90 m long) during 1990 were as follows:

To ask the Secretary of State for Scotland how many exceptionally large or heavy loads, requiring notification or escort by the police or local authority, were conveyed on the Scottish section of the A1 trunk road in each of the last 12 months.

Information on the differing types of exceptionally wide or heavy loads moving annually on the Scottish road network is not held on a centralised data base. Police and bridge authorities are notified in respect of their individual interest. There are many thousands of such notifications per annum on the road network and records for the A1 could be obtained only at disproportionate cost. The Lothian and Borders police however estimate that the number of exceptional loads on the A1 requiring accompaniment are in the region of 200 per annum.

To ask the Secretary of State for Scotland if he will list the road juctions with the A1 trunk road in Scotland which are being considered for safety improvement measures.

The first interim report of the A1 steering group has identified measures which could be taken at Coveyheugh junction, Greenwood junction, Knowes Farm Road junction, Huntington Road junction and at Gladsmuir.The Scottish Office Environment Department is discussing these measures with Borders and Lothian regional councils, my agents for maintaining the A1 trunk road in Scotland, with a view to the early implementation. The measures proposed involve the improvement of signing and road markings.
