Traffic has cleared following an earlier crash.

Hertfordshire Highways reported a collision in Hempstead Road at the junction of Courtlands Drive in Watford at around 11am.

The authority says travel time was 20 minutes longer heading into Watford - and warned that roadworks a little further down the road is adding to the traffic problems.

It was also busy heading out of Watford for some time too.

Traffic flow has now returned to normal.
