Yes, it's just south of the Catford gyratory on the A21. I think I was too far to the left really, I should have negotiated out after the WVM so I was riding to the right of the manhole covers. That would have been good for the blue car waiting on the left at the first t-junction, it probably would have stopped the muppet in the Audi from left hooking me, and would have been better on the two cars waiting at the junction just past.
