The A21 Sevenoaks Bypass is blocked south-bound, with traffic stationary due to a crash.

It happened on the A25 near the Westerham/Sevenoaks turn-off.

It's thought a van has gone through the barriers on the elevated section of the A21 above the M25 exit slip road.

Debris from the collision is believed to have fallen into the carriageway.

The exit slip road has been closed due to the accident on the elevated section of the A21.

All traffic is being forced to stay on the M25 anticlockwise carriageway. M26 westbound traffic can still access the M25 clockwise carriageway.

Meanwhile the M26 east-bound is closed from the M25 interchange to the M20 interchange, with congestion to Clacket Lane Services on the M25 anticlockwise.
