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.
This highway camera is on the northwest side of Highway 4 south of Sydney, looking northeast. It is at or near the little community of East Bay. In view on the left is St. Mary's Parish Church, a large wooden church, built in 1841. The camera is about 250 metres southwest of it.
