Motorists could face delays due to overnight roadworks on the M1.
Two lanes will be closed southbound between junctions 40 and 42 from 8pm until 6am until Sunday.
And two lanes will be closed northbound on the same stretch until Monday.
The junction 41 entry slip road will be closed tonight and on Thursday night.
But the Highways Agency said roadworks schedules often changed at very short notice.
