Two lanes of a motorway are closed after a collision - causing long queues.
National Highways says that the two slowest lanes are shut on the southbound side of the M1 between Junction 9 for Harpenden and Junction 8 for Hemel Hempstead.
It because of what has been called a “multi-vehicle collision”.
At the moment there are delays of 30 minutes and about three miles of congestion.
