Traffic chaos has erupted on the M25 QEII Bridge at the Dartford Crossing, with drivers facing delays of up to 75 minutes and five miles of congestion due to a broken down vehicle. National Highways has confirmed that one lane remains closed while recovery vehicles are en route. The situation has been exacerbated by an earlier stalled lorry, leading to significant backups as drivers approach the crossing. The AA has reported severe delays affecting traffic from as far as J29 A127 (Romford) and A13 queues from Grays. Although all lanes have now reopened, delays persist, currently estimated at 60 minutes. Motorway cameras show traffic at a standstill, highlighting the ongoing congestion. National Highways continues to monitor the situation and advises drivers to expect delays as recovery operations conclude.
