Civil engineers are giving Kansas’ infrastructure a grade of C minus.

The regional chapters of the American Society of Civil Engineers released the letter grade Wednesday. It’s part of a report card that evaluated the state’s aviation, bridges, dams, drinking water, energy, levees, railroads, roads and schools. Besides the state’s overall grade, each sub-category also received a grade.

The engineers found the most faults with the state’s bridges and dams, rating them a D-minus. The report said Kansas has nearly 3,000 structurally deficient bridges.

The highest grades awarded were for the state’s roads and schools, with both receiving a C-plus. The engineers noted that decreased funding is affecting road quality. They also said many of the state’s schools were built in the 1950s and are now 60 years old.
