Blue Reflectors
Monday, October 22nd, 2007Has anyone noticed the blue reflectors which have been appearing in the middle of the roads around Adelaide recently ? I have noticed that they always correspond to a nearby manhole cover, usually with a yellow dot on it. Not all manhole covers seem to have a corresponding nearby blue reflector though. I assume that the reflectors make it easy for maintenance people to find these particular manhole covers. Does anyone know what they are for ?
