Wisconsin Ranks 4th Worst for Road Quality. One in Three Roads Are in Poor Condition.

TL;DR

• Wisconsin ranks 4th worst for road quality with 29% of roads in poor condition and a roughness index of 136.0, per MoneyGeek/FHWA data.
• The state spends $23,657 per lane mile, slightly below the national average, ranking 38th for spending intensity.
• Extended freeze-thaw seasons (October through April) create more pavement damage cycles than most states.

Key Numbers at a Glance

Last verified: April 2026

Wisconsin's road quality ranking surprises a lot of people. The state is not usually in conversations about crumbling infrastructure. But the data is clear: 29% of roads in poor condition and the 4th worst roughness index in the country.

Why Wisconsin Roads Are So Rough

Extended freeze-thaw season. Wisconsin's winter starts earlier and ends later than most states. From October through April, the state experiences freeze-thaw cycles that crack and degrade pavement. That is 7 months of active road destruction.

Road salt dependency. Wisconsin uses heavy road salt application to manage ice. Salt accelerates pavement degradation by seeping into cracks and weakening the road base.

Moderate spending for a harsh climate. At $23,657 per lane mile (38th nationally), Wisconsin's spending is below average. For a state with one of the harshest climates for roads, this creates a maintenance gap.

Heavy agricultural and freight traffic. Wisconsin's economy depends on agriculture and manufacturing, both of which generate heavy truck traffic on state highways.

The Comparison That Matters

Minnesota, Wisconsin's neighbor, has nearly identical winter conditions. But Minnesota ranks 6th best for road quality with only 4% of roads in poor condition. Minnesota spends $22,004 per lane mile, actually less than Wisconsin. The difference is maintenance strategy, not budget.

Same climate. Similar spending. Dramatically different results. Minnesota's investment in preventive maintenance and data-driven repair scheduling outperforms Wisconsin's reactive approach.

What You Should Do

1. Budget $50 to $70 per month for road-related vehicle maintenance.
2. Get spring and fall alignment checks. The long freeze-thaw season means damage accumulates over 7 months.
3. Use winter tires from November through March. They handle rough surfaces better and reduce pothole impact damage.
4. Report road damage through WisDOT or your county highway department.
5. Shop for tires early. The 25% tariff on imported tires is pushing prices up.
