HC Deb 30 January 1967 vol 740 c34W
Mr. Peter Walker

asked the Minister of Transport what is the cost per mile of erecting a crash barrier in the middle strip of motorways; and what she estimates to be the cost of erecting a crash barrier that also prevented dazzle from headlights.

Mr. Swingler

The cost of a mile of double steel rail crash barrier is about £7,500, though other types now being developed should be somewhat cheaper. Expanded metal mesh anti-dazzle fence costs about £5,500 per mile. We are not aware of the existence of any practical crash barrier for use in this country which also acts as an anti-dazzle screen.
