If we're doing the math correctly, this means there are actually eight states with roads that are worse than ours. That's hard to believe, isn't it?

What States in the US Have the Worst Roads?

Michigan's freeze-thaw cycle certainly contributes to the number of potholes we have in our state but the state with the worst roads in the United States rarely if ever sees snow. California's roads are said to be worse than any other state's.

Here are the 10 states with the worst roads:

  1. California
  2. Rhode Island
  3. Nebraska
  4. Wisconsin
  5. New York
  6. Hawaii
  7. Massachusetts
  8. Louisiana
  9. Michigan
  10. New Jersey

How Are the Worst Roads in the US Determined?

The website MoneyGeek pored through the data and crunched the numbers based on road roughness. According to the website, "the road roughness index is the weighted average value of the observed measurements of the international roughness index (IRI) for the state."

According to the Federal Highway Administration, the higher the IRI number, the rougher the road is.

  • If a road gets an IRI number of 95 or less, the road is considered to be in good shape.
  • An IRI score of 170 or more indicates that a road is in rough shape.

According to the study, 44% of California's roads are considered to be in poor condition, while only 24% of Michigan's roads get a failing grade.

On the other hand, 38% of Michigan's roads are considered good, while only 22% of California's roads get the 'good' designation.
