They've been digging on the island of the A77 at the Dutch House Roundabout for a couple of weeks now with no sign of what they were doing. This morning, two new poles with cameras have appeared. The poles are blue [1] fancy victorian style that stretch over both carriageways. The cameras are small and square, like you see on the motorway, and yellow. They also have two smaller yellow boxes either side. Are these some kind of sensor? Any idea what these cameras are? I don't know if they are just the traffic monitoring type. They seem awfully prominiently placed for that. [1]The colour of the pole is probably not relevant.
