I realise the traffic flow out of a Town match nowadays will be minimal, but does anyone out there know why three lanes of the M1 southbound near Tibshelf were closed last night? There seemed to be no accident and I only saw three works vans, doing not much. Northbound seemed rammed by something, too. So frustrating to be backed up for ages, finally reach the roadworks and see that nobody is there doing anything on the three closed lanes......
