The M20 has been closed in both directions after a serious crash near Wrotham, where a lorry cab fell from a bridge onto the motorway below.

Emergency services, including the air ambulance, are at the scene after the driver of a cab/tractor unit towing a trailer reportedly lost control on the A20 bridge. The cab crashed through the barriers and fell onto the London-bound M20 carriageway.

National Highways confirmed:

• The London-bound carriageway is closed between Junction 3 (M26 interchange) and Junction 1 (Swanley).

• The coastbound carriageway is closed between Junction 2 (A20 Wrotham/Brands Hatch) and Junction 3.

Traffic is being diverted via local roads, with major delays across the A20, A25 and M25 approaches.

A National Highways spokesperson said:

“The M20 remains closed in both directions following a serious collision involving a lorry which has left the carriageway. Emergency services, including the air ambulance, are on scene.”

It is not yet confirmed whether there are any injuries, but the motorway is expected to remain shut for several hours while specialist recovery work and investigations take place.

Drivers are being urged to avoid the area and allow extra time for their journeys.
