While our roads and bridges are improving, Michigan’s “mediocre” infrastructure still needs major improvements, according to the American Society of Civil Engineers’ (ASCE) latest report card.

Driving the news: Michigan’s C- is the same as the nation’s overall grade and is an upgrade from the D+ the state received in 2018.

Grades for drinking water, stormwater, rail, roads and schools improved while grades for bridges and energy infrastructure got worse.

Details: The energy grade dropped from a C- in 2018 to a D as leaders from DTE and Consumers Energy have said they are working to improve reliability amid severe weather conditions and blackouts last winter.

Of Michigan’s 11,314 bridges, approximately 1,269 (11%) are in poor condition. That’s stable from 11% in 2018 but higher than the 7.5% national average.

What they’re saying: “A C- means our infrastructure is in mediocre condition and requires attention,” Brad Ewart, president of the ASCE’s Michigan section, said in a statement.

The ASCE wrote it would take a near $4 billion investment to get Michigan’s infrastructure report card to an A.

The big picture: The state must implement sustainable and long-term funding solutions, address workforce challenges and prioritize resilience and reliability, engineers wrote.
