Tailbacks on the Dartford Crossing are reportedly stretching back for 10 miles. 

Long delays on the M25 road are said to be affecting the A282 Dartford River Crossing toll booths travelling anticlockwise. 

Congestion is said to be filtering down as far as Orpington, apparently causing travel time of around an hour and 10 minutes. 

People are, unsurprisingly, upset.

There is also slow traffic on the A2 London-bound and the Darenth Interchange for the Bluewater shopping centre.
