South Dakota DOT Cameras — Live Road Cameras & Map

In South Dakota, the camera and the weather come together. Like neighboring Montana and North Dakota, most of the SDDOT camera network is built on top of the state's Road Weather Information System (RWIS): roughly 132 roadside weather sites carry a co-located camera, and another 43 traffic cameras watch the interstates, for about 175 views in all. That means when you open the map, most images arrive with real on-the-road weather beside them — air temperature, pavement (surface) temperature where the sensor reports it, surface condition, and wind — not a reading from a distant airport.

That on-road data is exactly what you want for a South Dakota winter. A road can look merely wet on camera and still be glazed with ice if the pavement is sitting below freezing, and the open-prairie ground blizzards the state is known for can drop visibility to zero on a day with little new snow. The RWIS surface and wind readings, paired with the live image, give you a far better read on ice and blowing snow than any forecast can. SDDOT publishes it all on sd511.org through the Iteris system.

Coverage follows the traffic. The cameras are densest along the cross-state spine of I-90 — Sioux Falls, Mitchell, Chamberlain at the Missouri River, Murdo, Wall, and Rapid City out to the Wyoming line — and the I-29 eastern tier from Sioux Falls up through Brookings and Watertown toward North Dakota, with more clustered around Pierre, Aberdeen, and the Black Hills. Use the area presets below to jump straight to your corridor, then read the on-road weather next to each image before you commit to a drive.
