HC Deb 08 April 1987 vol 114 c249W
Mr. Greg Knight

asked the Secretary of State for Transport if he will list the dates, times and places during which stretches of the M1 motorway between Derby (junction 25) and London have been reduced to single file traffic since January 1986.

Mr. Peter Bottomley

The information requested is not available. Where work involving single file running is planned, it is where possible carried out overnight or at other times when traffic volumes are at a minimum. We try to keep traffic disruption and delays to a minimum. Single lane running is only employed where there is no reasonable alternative.
