Outside 153 Sydenham Lane, BS6. There's obviously been some roadworks here in the past running diagonally across the road. One part of this is sinking and at its deepest is 80-100mm below the level of the surrounding road surface. Circled in the attached photos. They don't really show the severity of it but it causes quite a jolt to vehicles driving over it and their occupants. It seems to have got worse in the last couple of months.
