LANSING, Mich. (WILX) – The 2018 Report Card for Michigan’s Infrastructure comes back with an overall grade point average of D+.

At a news conference on Tuesday, the Michigan Section of the American Society of Civil Engineers (ASCE) released the report.

The report included an evaluation of Michigan aviation, bridges, dams, drinking water, energy, navigation, rail, roads, schools, solid waste, storm water, transit and wastewater.

The grades on the report card ranged from the highest grade of C+ for Solid Waste to the lowest grade of a D- for roads and storm water. The report also found that much of the state’s infrastructure is toward the end of it’s useful life, which threatens Michigan’s lakes, rivers, drinking water, and public health.
