HC Deb 15 November 1985 vol 86 cc329-30W
Mr. Rost

asked the Secretary of State for Transport what is the length of the A1(M) motorway which it is proposed to cut and cover at Hatfield; and what is the estimated additional cost.

Mrs. Chalker

The A1(M) Roestock to Stanborough scheme at Hatfield is in total 4 miles long, and the cut-and-cover tunnel section approximately three quarters of a mile. A scheme with a section in open cutting along the tunnel length would at spring 1984 prices have cost an estimated £14.5 million less.
