This one comes out of a conversation I had with a colleague about the proliferation of traffic lights in Inverness in recent decades. Maybe SP, Jock Watt, CMIB or Canuck can do better than I can, but I certainly remember when there were just THREE sets of traffic lights in the town at Kenneth Street, the Town Hall/ steeple (where they no longer are!) and "Boots Corner".
At this point I am going back to the 60s, possibly the fairly early 60s, and I am also trying to remember where the fourth set went.... was it possibly the junction of Drummond Road and Culduthel Road?
But it's remarkable, isn't it, that traffic density in our ancient Royal Burgh used to be such that, within the living memory of quite a few, it could be controlled by just three sets of lights. On the other hand we are talking about days when the said traffic included horse drawn Stratton milk floats!
