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 camera is mounted on the east side of Highway 125, AKA Peacekeepers Way, at Pottle Lake, slightly north of Regent Street in North Sydney. It looks south down Highway 125, with Pottle Lake in view to the right.
