M25 near Dartford crossing closed in both directions: Major delays

The M25 near Dartford crossing has been completely closed in each direction this afternoon after an accident.

The accident involves two vans and a car. Bridge damage is also reported according to Highways England, who state 75 minutes queues, though some have complained of being stuck for over two hours and counting:

Highways England state:

The M25 is closed in both directions between J1A – J2 for bridge assessments to take place after a collision.

A bridge inspector is en-route.

Road users travelling clockwise are advised to follow the hollow triangle diversion route:

  • From M25 Junction 1A exit slip to roundabout “Littlebrook Interchange”, take 2nd exit onto A206 towards Greenhithe.

  • At A206 / A226 roundabout take 2nd exit onto B255 towards Bean.

  • Follow B255 past Bluewater to the A2 North Junction roundabout, take 2nd exit and cross the A2 to the South Junction roundabout and take 1st exit onto A2 towards London.

  • Follow A2 to M25 Junction 2 “Darenth Interchange” and then take 1st exit to re-join M25 towards Gatwick.

The Blackwall tunnel is already slow going in Greenwich as traffic diverts.

Northbound queues extend back as far as Sun in the Sand roundabout.

Diversions are in place.

    • Initial thoughts are with those involved in accident but then…………
      Oh no, another afternoon of gridlock Greenwich!

    • I hope everyone involved in the accident are ok and go on to make a full recovery.

      However, Greenwich is gridlocked yet again this afternoon and that is even before the Silvertown Tunnel opens. Traffic congestion and air pollution is only set to get worse around the Borough of Greenwich and neighbouring Boroughs. Despite an increase in respiratory related illnesses.

    • Welcome to the future of travelling in and around Greenwich Borough this will become the norm when the Silvertown Tunnel opens. Traffic is already more gongested in the area due to cycle lanes which have been installed meaning buses now stop in the middle of the road so other traffic is unable to pass.

      Even worse is the fact is that this seriously delays emergency vehicles including ambulancess Fire Engines and police cars from getting through. A lot of people say that is not a problem until one of your on is affected by a delayed emergency vehicle that cannot get through the traffic then all hell wll break loose blaming the emergency services.
