An earlier crash is causing heavy traffic on the M25 and roads in and around Rickmansworth.

There was a collision earlier this afternoon on the clockwise carriageway at junction 20 for Kings Langley.

Highways England is reporting that all lanes have reopened - however there are tailbacks.

Many drivers have left the M25 and headed through Rickmansworth and Chorleywood.

As a result, the A412 Uxbridge Road is slow all the way into Rickmansworth town centre from Maple Cross.

Chorleywood Road is slow in both directions between the A412 and the M25 at junction 18.

And Langleybury Lane towards Hunton Bridge is also queuing.

The delays on the M25 have cleared clockwise between junctions 18 and 20, but there are queues between junctions 16 and 18.

Meanwhile, there has been lots of slow traffic in Watford today.

Temporary traffic lights at the junction of Wiggenhall Road and Thomas Sawyer Way have caused problems while Pinner Road and Eastbury Road have both been very slow into Bushey Arches.
