States Where Road Conditions Are Deteriorating Fastest

The United States boasts an impressive interstate network of 4.2 million miles of roads—but underlying that reputation is a backlog of $786 billion in needed repairs, according to the American Society of Civil Engineers. On average, the society estimates, American motorists spend a collective $130 billion on extra vehicle repairs and fuel costs as a result of driving on poor-quality roads and bridges.

‍

In 2000, 82.6% of U.S. roads were considered acceptable to drive on, according to federal standards, which look at how rough or smooth a road surface is based on how much vibration a car's suspension has to absorb while driving on it. By 2020, a smaller share—81%—of U.S. roads were rated acceptable.

‍

TruckInfo.net used Bureau of Transportation Statistics data to map and rank U.S. states by the change in the share of roads that were in acceptable condition over the past two decades. Road condition is determined by the International Roughness Index, which measures deviations from pavement surfaces significant enough to affect driving. Roads with IRI values below 170 are considered to be in acceptable condition, while anything above 170 is considered poor condition. Data represents the percentage point change from 2000 to 2020.

Fewer roads are in acceptable condition in 2020

At first glance, the change in the share of roads in acceptable condition over the past two decades does not appear to be a significant downgrade. However, the nationwide change can be misleading because while some states have improved their road infrastructure, some states have seen a massive decrease in road quality.

‍

States like Rhode Island and Washington have seen over 20% of their roads degrade into poor condition. Other states, including Arkansas and Oklahoma, have conversely seen significant improvements in the quality of their roadways, and are planning to invest more by implementing state-initiated projects and tax hikes. California, which has seen road conditions improve, depends on higher-than-average gas taxes to fund road repair and construction.

States where roads have been deteriorating the fastest

#51. Arkansas

- Share of roads in acceptable condition, 2020: 92.0%
- Change from 2000: +26.8 percentage points

Road conditions have improved the most in Arkansas from 2000 to 2020. Exactly 92% of roads are in acceptable condition, a huge increase from 65.21% in 2000. In 2020, Arkansas voters passed an amendment to the state constitution that mandated a half-cent sales tax to go toward road construction projects, an initiative designed to produce approximately $290 million in revenue each year.

‍

#50. Oklahoma

- Share of roads in acceptable condition, 2020: 93.7%
- Change from 2000: +25.5 percentage points

Oklahoma has had the second-greatest improvement in road conditions of all states. In 2000, 68.2% of roads were in acceptable condition. That percentage has since surged to 93.65% in 2020. The Oklahoma Department of Transportation is currently one year into an eight-year effort to spend $8 billion on highways.

‍

#49. Hawaii

- Share of roads in acceptable condition, 2020: 60.0%

While only 60% of the roads in Hawaii were in acceptable condition in 2020, the state actually saw a 10 percentage point improvement from 2000. Despite the conditions of roads in the state, Hawaii has the fourth lowest car crash fatality rate in the nation due in part to having the lowest speed limits and less miles of roadway (9,972) compared to other states.

‍

#48. California

- Share of roads in acceptable condition, 2020: 67.0%
- Change from 2000: +9.7 percentage points

California roadways have undergone significant improvement in recent decades. In 2000, just 57.35% of roads were in acceptable condition; in 2020, 67% were considered acceptable. This may come as no surprise given the fact that California has the highest gas tax at 77.9 cents per gallon, which goes exclusively toward highway repair and maintenance.
