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 mounted on the north side of Highway 104, on the Canso Causeway. It is less than 50 metres west of the green truss bridge over the Canso Canal. About half a kilometre west of Port Hastings, the camera looks southwest down the causeway.
