I went past it about 6:45, looked like it had not lomg happened. Was right on J3 as you exit for APH/asda/woodchurch etc. Looked like a range rover with half its front end all over the road, a small red car (maybe a new shape micra?) Which i couldnt see the damage on And a dark small grey/dark car (old style punto maybe?) That again i didnt see the damage of. There were about 4 police cars, 2 ambulances, 1 fire engine at the scene... lane 1 shut and 30mph restrictions in place but traffic seemed ok. On the way back however about 15 mins later it was gridlock and tailed right back to the tunnel.
Hope everyones ok, it looked bad though.
