Kent Police are advising drivers to avoid the M20 between junctions 3 and 1 on the London-bound carriageway after a serious accident.
Police were called at 5.10am to a report that a lorry had jack-knifed and collided with the near-side barrier before falling down an embankment.
M20 London bound closed, very slow traffic due to recovery work and earlier accident, a lorry down the embankment involved between J3 M26 and M25 / A20 (Swanley Interchange), congestion on M20 to J4 A228 (Leybourne / Snodland).
The main problem is for traffic heading from Kent to Essex as there is no direct access to anticlockwise M25 from the M26. Police say the road will be closed until at least lunchtime.
Diversion - for traffic wanting to use the anticlockwise M25- travel to J6 at Godstone and turn around.
We're now getting reports that queues on the M20 in Kent are causing delays through Maidstone.

We're getting reports of major delays on the M20 in Kent after a lorry went down an embankment at J3 with tailbacks to J7.
Severe delays due to earlier accident on M25 anticlockwise between Clacket Lane Services and J5 M26 / A21, congestion on M25 to J9 A243 / A244 / B2430 (Leatherhead).
Lanes one and two (of three) were closed from about 2.30pm until 7.30pm following an accident within the roadworks. Long queues are still being reported with delays of well over two hours.
Road users are advised that two lanes are still closed on the anti-clockwise M25 between junctions 6 and 5 in Kent due to an incident.
The incident, which happened just before 2.30pm, involved a lorry and a car. Delays are severe with queues past junction 8.
The Highways Agency and its contractors are working hard to reopen the lanes as soon as it is safe to do so, but it is expected that recovery will take some time as the lorry is stuck on the verge.
There are concrete bollards on the carriageway which need to be cleared. Once this is done an assessment will be made of the carriageway and it is hoped to re-open a second lane.
Detectives investigating three reports of pellets being fired at moving vehicles on the M20 have arrested five people.
