Highways and Maps

Navigating your way around scenic state highways, back roads and Interstates through SoDak.

Wide-open prairies and winding roads. Uninterrupted sky views and towering, iconic monuments. Soft, green hills and one-of-a-kind rock formations. These are only some of the sights that can be experienced from the roads of South Dakota. The state's variety of landscapes show why South Dakota prides itself as the home of "Great Faces, Great Places." Whether you're in the driver's seat or pedaling your bicycle, scenic routes like the Peter Norbeck National Scenic Byway and the Native American State and National Scenic Byway are but two ways to absorb the magnificent beauty of South Dakota. Check out the adventures of other travelers and keep reading for the best ways to make the most of your visit.

Begin planning your road trip with the basics. Two interstate highways cut across South Dakota. Interstate 90 runs east-west through the state with access to Sioux Falls, Mitchell, Rapid City and Spearfish. Interstate 29 runs north-south through the eastern part of the state from the North Dakota border through Watertown, Brookings, Sioux Falls and North Sioux City. These interstates can help you make good time, but you can expand upon your experience by exploring alternate routes and scenic byways whenever possible.
