There are long delays on the M25 approach to the Dartford Crossing this afternoon (September 12).
A broken down horsebox which is towing a caravan has blocked the left hand tunnel.
It resulted in Northbound traffic being diverted via the East Tunnel (which is the taller of the two).
Long delays have built as a result with traffic queuing back to Swanley.
