Infrastructure in South Carolina

South Carolina Infrastructure Overview

While the nation’s infrastructure earned a “D+” in the 2017 Infrastructure Report Card, South Carolina faces infrastructure challenges of its own. For example, driving on roads in need of repair in South Carolina costs each driver $502 per year, and 10.3% of bridges are rated structurally deficient. Drinking water needs in South Carolina are an estimated $1.8 billion. 178 dams are considered to be high-hazard potential. The state’s schools have an estimated capital expenditure gap of $90 million. This deteriorating infrastructure impedes South Carolina’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 Carolina, and families can no longer afford.
