That's a shame Paul, was a really good evening!
Would have thought you'd been ok, as you would of turned off just before the Medway bridge. The crash was just up from Jn 4 (my home turn off). I left home at 7pm & jn's 3> 4 were closed, but the Q was not too bad, ie it lead from my side of the bridge up to jn 3 (Blue Bell hill). Of course you never know!
