HC Deb 01 December 1986 vol 106 c512W
Mr. Latham

asked the Secretary of State for Transport what information he has as to the reasons for the traffic jam on the north-bound carriageway of the M1 between junctions 12 and 13 on 20 November between 23.15 hours and midnight; and what steps were taken to minimise the inconvenience to road users.

Mr. Peter Bottomley

Lane closures were in force to allow improvements to the motorway signalling. Although evening working was deliberately chosen to minimise disruption, the onset of heavy rain and several vehicle breakdowns unfortunately combined to cause the tailback.
