Infrastructure in South Dakota

South Dakota Infrastructure Overview

While the nation’s infrastructure earned a C- in the 2021 Infrastructure Report Card, South Dakota faces infrastructure challenges of its own. For example, driving on roads in need of repair in South Dakota costs each driver $562 per year, and 17% of bridges are rated structurally deficient. Drinking water needs in South Dakota are an estimated $730 million. 90 dams are considered to be high-hazard potential. The state’s schools have an estimated capital expenditure gap of $125 million. This deteriorating infrastructure impedes South Dakota’s ability to compete in an increasingly global marketplace. Success in a 21st-century economy requires serious, sustained leadership on infrastructure investment at all levels of government. Delaying these investments only escalates the cost and risks of an aging infrastructure system, an option that the country, South Dakota, and families can no longer afford.
