ST PAUL, Minn. — Minnesota's infrastructure maintained a "C" grade in the latest report card from the American Society of Civil Engineers (ASCE).
The state's highest grades (B-) were in aviation and public parks, while it received a D+ in roads.
The report card grades 11 categories of infrastructure, including aviation, public barks, bridges, energy, dams, ports, stormwater, transit, wastewater, drinking water and roads. According to the ASCE, Minnesota improved in four categories (bridges, energy, ports, transit) and decreased in one (aviation). Its overall "C" grade matches the national average from the ASCE's 2025 report card.
“Minnesotans should be proud of the progress made to improve infrastructure systems that keep businesses and communities thriving and help maintain a high quality of life for all Minnesotans,” said Hannah Albertus-Benham, PE, chair of the 2026 Report Card for Minnesota’s Infrastructure, in a press release. “However, we are at risk of losing these gains as temporary infrastructure funding measures expire. Minnesota’s infrastructure systems need dependable, consistent, and sustainable funding sources to ensure communities can keep systems thriving and plan for the future.”
Here's the full report card:
Aviation: B-
Bridges: C+
Dams: C
Drinking water: C-
Energy: C+
Ports: C
Public parks: B-
Roads: D+
Stormwater: C
Transit: C
Wastewater: C
While roads were graded the worst, the state's busiest roads rated the best, with 93% of interstate highway miles in Minnesota rated in "good condition," according to the report. The ASCE also warns that there's a $20 billion road funding shortfall over the next 20 years, which could lead to declining performance in future report cards.
"Recent increases in state and federal funding, including $5.2 billion from a 2023 bill, have helped but remain short-term solutions and do not close the long-term gap," the report reads. "Without major new investment, a significant share of Minnesota’s roads could fall into poor condition by 2034.
