HC Deb 08 February 1967 vol 740 c324W
107. Sir Clive Bossom

asked the Minister of Transport why it was decided to install steel lighting standards on the central reservation of the Chiswick end of the M4 contrary to the findings of the Road Research Laboratory that such standards so situated constitute an accident hazard; and whether it is proposed to erect crash barriers along the edges of the central reservation.

Mr. Swingler

At present the most efficient and economical lighting of a motorway of this width and layout is achieved by columns on the central reservation. Steel crash barriers will shortly be erected to protect the columns and to safeguard vehicles.
