Nova Scotia highway webcams are operated by the Nova Scotia Department of Transportation and Infrastructure Renewal (TIR). Most are mounted on tall steel towers, most of which have weather sensors included on the tower. The sensors measure temperature, humidity, barometric pressure and wind direction and speed.
The webcam pic below is more or less real time and will update every 30 to 40 minutes, depending on conditions.
The Pictou Causeway highway camera is mounted on the east side of Highway 106, the Trans Canada Highway, near the north end of the causeway, looking south down the causeway. The Trans Canada crosses Pictou Harbour on the causeway just west and south of the town on its way north to the Caribou, Nova Scotia - Wood Islands, Prince Edward Island ferry.
