One lane is closed on the M1 this evening because of a crash.

Emergency services are at the scene of the incident which has taken place between j4 and j5 for Watford.

There are very long queues between the two junctions with the crash just as you approach j5.

Meanwhile, in Watford itself, traffic is busier than usual along Vicarage Road all the way round to the junction of Wiggenhall Road and Eastbury Road.

There are also queues in both directions approaching the Dome roundabout on the A41 and on the A4008 out of town towards the M1 roundabout.
