South Dakota DOT Cameras — Live Road Cameras & Map
All South Dakota DOT cameras — interactive statewide map
About this 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.

Statewide
The full SDDOT network on one map: about 175 cameras spanning I-90, I-29, I-229, US-83, US-14, US-212, US-281, and the Black Hills routes. Most are RWIS sites, so most images come with on-road air and pavement temperature, surface condition, and wind. Start here for a whole-state picture in winter, when ground blizzards can close interstates hundreds of miles apart at once, then zoom to your corridor.
Sioux Falls
South Dakota's largest city and the only place its two interstates meet. I-90 and I-29 cross here, and the I-229 loop wraps the south and east sides of town. Cameras cover those interchanges plus the approaches toward Brandon, Tea, and Harrisburg. It's the eastern gateway to the whole state — check it before heading west on I-90 toward Mitchell or north on I-29 toward Brookings.
Black Hills & Rapid City
Rapid City is the gateway to the Black Hills, and the cameras here cover both the I-90 corridor (Sturgis, Spearfish, Box Elder) and the mountain routes climbing south and west — US-16 toward Mount Rushmore and Keystone, US-385 and US-85 into Custer, Deadwood, and Lead. The Black Hills see heavier mountain snow than the plains, so this preset matters in shoulder season; check it before any Rushmore, Custer State Park, or Spearfish Canyon run.
I-90 Central
The exposed middle of the cross-state spine: Mitchell and the Corn Palace, Chamberlain and the Missouri River crossing, Murdo, and Wall, gateway to the Badlands and Wall Drug. This is wide-open, wind-raked prairie where ground blizzards close the interstate even with little new snow. The RWIS surface and wind readings out here are your best early warning before committing to the long rural gaps between towns.
I-29 Corridor
The eastern tier north-south: I-29 from Sioux Falls through Brookings and Watertown to the North Dakota line near New Effington. The flat, wind-exposed terrain of the eastern prairie can close this route border-to-border in a blizzard, the same way it does across the line in North Dakota. Use this preset to scan the rural stretches between cities, where blowing and drifting snow strikes first.
Pierre & Missouri River
The capital region along the Missouri. US-83 runs north-south through Pierre, the state capital, linking US-14 across the central plains near Lake Oahe. This is open central South Dakota, far from the interstates, so cameras are sparser but valuable — they show whether the two-lane US routes are drivable when winter wind picks up loose snow off the surrounding prairie and lake country.
Aberdeen & Northeast
The northeastern corner: Aberdeen at the hub of US-12, US-281, and US-281, plus the US-12 link from I-29 at Summit toward Aberdeen and Milbank. This is glacial-lakes prairie that gets the same open-country ground blizzards as the I-29 corridor. Check it before driving the northeastern two-lane routes in winter, when blowing snow and extreme cold can make a clear-sky day deceptively dangerous.
Tips for using South Dakota road cameras
- Trust the pavement temperature over the look of the road. On a South Dakota RWIS camera, a surface that looks merely wet can be black ice if the pavement reading is below freezing — treat any ice or trace-moisture surface reading as a real warning.
- Watch the wind, not just the snow. The ground blizzards that close I-90 and I-29 are driven by wind lifting loose snow off the prairie. A high wind reading next to a clear image is a sign visibility can vanish in seconds out on the open stretches.
- Scan the rural gaps first. The dangerous whiteouts happen between towns — the long open runs of I-90 west of Mitchell or I-29 between Brookings and Watertown — so check those cameras before the in-town ones.
- Respect the gates. When SDDOT posts No Travel Advised or physically closes I-90 or I-29, there is rarely a safe detour, because the parallel US routes are just as exposed. Driving a closed road is prohibited; wait it out and keep checking the cameras.
- Give the Black Hills extra margin. Rapid City and the Hills get heavier mountain snow than the plains, and routes like US-16 to Mount Rushmore or US-385 toward Deadwood can be snowpacked when the interstate is dry. Check the Black Hills preset separately, not just the I-90 cameras.
- Always confirm closures and conditions at the source. The cameras are a great gut check, but South Dakota closes roads fast — verify current closures, gate status, and No Travel advisories at sd511.org or by dialing 511 before you go.
