In 2007 South Dakota had 134,773 km (83,744 mi) of highways, of which 1,093 km (679 mi) were part of the federal interstate highway system. Principal routes were Interstate 90, which travels east-west through the heart of the state, and Interstate 29, oriented north-south along the state’s eastern border. South Dakota has 7 airports, most of which are private. None of the state’s commercial airports are considered busy by national standards. Sioux Falls has the busiest airport.
Farm products make up 70 percent of the rail tonnage originating in South Dakota. Trains are also heavily used to haul nonmetallic minerals in the state.
The state is served by 2,956 km (1,837 mi) of railroad track. Beginning in 1980 the state government bought abandoned private rail lines. This action enabled these lines to continue to provide rail access. Today, Burlington Northern Santa Fe, Union Pacific, and the Dakota Minnesota & Eastern are the principal railroads in the state.
Hydroelectric power plants generate 47 percent of the state’s electricity. The largest hydropower dams in terms of capacity are those at Gavins Point, Fort Randall, Oahe, and Big Bend on the Missouri River. The remainder of the state’s electricity is generated in thermal plants, mostly fueled by coal. Power is also brought in from utility plants in neighboring states.
