Severe delays at Blackwall tunnel, Woolwich ferry and Dartford
There are severe delays at all crossings of the Thames between east and south east London and beyond this afternoon after a collision on the Dartford crossing.
Miles of queues are in place at the approach to the Blackwall crossing with traffic backed up for the entire length of the A2 and A102 between the M25 and Greenwich then back into east London.
Extremely long waits for the Woolwich ferry are also seen, with numerous bus routes delayed.
Earlier today at around 11 am a collision between a lorry and car on the Dartford crossing resulted in a fuel spill and damaged barriers.
The road surface and barriers were damaged in the crash and repairs are ongoing, with closure expected to continue into the evening.

I don’t understand. Was not the Silvertown tunnel meant to be a “relief” route?
