HC Deb 13 February 1989 vol 147 c100W
63. Mr. Higgins

To ask the Secretary of State for Transport if he will install on the central reservation of the M25 motorway appropriate traffic lights and gates at suitable intervals which can be opened by the police to allow vehicles in major traffic jams on one carriageway to enter the carriageway going in the opposite direction in order to leave the motorway.

Mr. Peter Bottomley

Any benefit from such an arrangement would be outweighed by the practical difficulties of establishing and operating it, and by the adverse safety implications to which it would give rise.
