London Council create a hazard

I thought you might like to see these pictures taken at Garratt Lane in Wandsworth. South London.

What you can see is a sheet of metal 4ft x 2ft and raised 2 inches above the tarmac. I have no idea what its covering, because the road was fine a week ago. God knows what would happen in the wet because it’s even on a bend!! It’s a disgrace to think that can be just put in the middle of the road and no one seems to care!
