The Dartford Crossing is completely blocked southbound after a crash between several lorries closed all four lanes.

Traffic is being diverted via slip roads, but the roads are not expected to be fully cleared for another two hours.

The site of the crash, which involved two HGV lorries and a car transporter, has been attended by emergency services.

Commuters have been sharing images of the congestion on Twitter. One user said: “absolute gridlock on the Dartford crossing!”

Another said: “When will @HighwaysEngland @KentHighways do something about this dangerous junction.”

With traffic queueing back over the QE2 Bridge, drivers are being advised to take alternative routes while the gridlock is being cleared.
