Infrastructure in Delaware

Delaware Infrastructure Overview

While the nation’s infrastructure earned a “D+” in the 2017 Infrastructure Report Card, Delaware faces infrastructure challenges of its own. For example, driving on roads in need of repair in Delaware costs each driver $487 per year, and 4.4% of bridges are rated structurally deficient. Drinking water needs in Delaware are an estimated $1.74 billion, and wastewater needs total $206 million. 63 dams are considered to be high-hazard potential. The state’s schools have an estimated capital expenditure gap of $102 million. This deteriorating infrastructure impedes Delaware’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, Delaware, and families can no longer afford.
