HC Deb 07 February 1969 vol 777 cc189-90W
Mrs. Ewing

asked the Secretary of State for Scotland what is the extent of under-road heating in Scotland.

Mr. Ross

Because of its high cost under-road heating is employed only at a few specially selected locations where icy conditions would cause exceptional hazards.

Mrs. Ewing

asked the Secretary of State for Scotland what estimate he has made of the present capital costs for under-road heating in Scotland.

Mr. Ross

Where electric power supplies are at hand the cost of installing road heating is estimated to average about £3 10s. per square yard of carriageway.
