As I was driving up the bridge I saw around 10 -12 damaged cars scattered on the opposite side of the carriageway so at that stage it had only just started.
It seems that people didn't slow down or use their lights so they just kept crashing into each other when the distance closed.
At the last count it was 130 vehicles involved, 8 badly injured and 200 people affected.
By the time I got back over the 2nd bridge ( which we all rode over) the big one was full of emergency vehicles, wreckers, news crews and all kinds of debris.
It re opened around 5pm.
I also spent 1 1/2 hours parked on the M20 when a motorcyclist had a bad one after J9.
When I eventually came back the opposite way there was a Kawasaki GPZ750 totalled in the fast lane with no sign of a clean up or the rider.
The rider may have been a lady.
