Connected at the Core of the Country

South Dakota is at the heart of the United States in the most literal sense. Home to the geographical center of the country, South Dakota companies have swift access to all major U.S. regions thanks to a robust network of highways and railroads. Apart from being just a short distance from several major metros, seven commercial airports make it easy to stay globally connected while remaining locally invested. And with 77,116 square miles to our name, a reliable system of telecommunications support ensures that companies are always connected wherever they operate.


Hit the road in South Dakota and you’ve got your pick of destinations. With two major interstates, there’s no place you can’t go from the geographical core of the United States. I-90 runs east and west, while I-29 flanks the eastern part of the state from the north to the south. Three high-priority corridors play a role in our extensive network of roads which helps keep consumers connected to South Dakota goods and products:

  • Corridor 23, begins in Laredo, Texas and runs north through the eastern part of the state up to the Canadian border. I-29 which runs through Sioux Falls is part of this highway system.
  • The Heartland Expressway connects Rapid City in the western part of the state to Denver. When construction on this corridor is complete, this four-lane highway will directly connect western South Dakota and Texas.
  • The Theodore Roosevelt Expressway starts in Rapid City and takes drivers north to North Dakota, Montana and the international border with Canada.

South Dakota ranks fourth best in urban pavement conditions, eighth best in rural pavement conditions, and fifth best (lowest) in urbanized area congestion.

Rail holds a prominent place in South Dakota’s history and economic development with the completion of the Southern Dakota Railroad in 1872. Today, shipping goods to and from South Dakota is possible thanks to ten freight railroads operating nearly 2,000 miles of track. Our rail network consists of Class I, Regional, Local and Switching lines with BNSF playing the most prominent role in South Dakota freight.


Sioux Falls Regional Airport and Rapid City Regional Airport account for South Dakota’s largest airports in terms of passenger traffic. Rapid City Regional Airport offers direct flights to nine major U.S. cities including Chicago, Dallas-Fort Worth, Denver, and Minneapolis. Sioux Falls Regional Airport has direct flights to sixteen destinations with direct service to major U.S. airport hubs such as Atlanta, Chicago, Dallas-Fort Worth, Denver, Minneapolis, and Orlando.

The cities of Aberdeen, Pierre, and Watertown also operate commercial air service and charters, which means that you’re always just a short flight away from some of the largest airports in the country.


South Dakota has a vast network of telecom providers that ensures that our residents and companies are globally connected 24/7 with reliable service, regardless of their location. In the past decade, the state prioritized bringing high-speed broadband capability to South Dakota statewide. Today, we boast more than 44,000 miles of fiber optic cable.
