This year’s Better Roads Bridge Inventory shows that while the total number of bridges has risen since 2023, the number of bridges rated in “good” condition went down.

Data from the Federal Highway Administration shows that, as of June 15, 2024, the U.S. has 620,762 bridges, up 0.3% from 619,175 at the same time last year. Data shows 44.20% of those bridges or 274,407 are rated in good condition, down slightly from 44.36% and 274,675 in 2023.

The percentage of those bridges in “fair” condition rose by 2,217 to 304,620 bridges, which went from 48.84% of all bridges in 2023 to now 49.07%. This category has grown over the last five years, while the number of good condition bridges has fallen.

Welcome to Equipment World’s 2024 Better Roads Bridge Inventory. What follows are some snapshots from data compiled from FHWA Bridge Condition reports, submitted by departments of transportation for all 50 states and the District of Columbia as of June 15, 2024. We rank the top and bottom states in various categories using that data. At the end of the article, we also provide a detailed look at overall conditions of the bridges in each state, so you can see how your state stacks up.

Note the data shown in this article includes federal bridges and excludes data from Guam, Puerto Rico and the Virgin Islands.

Understanding bridge condition ratings

The Federal Highway Administration asks states to rate bridges that are 20 feet or longer as “Good,” “Fair” or “Poor.”

GOOD – Bridges in this category range from excellent to some minor problems.

FAIR – Ranging from bridges with structural elements showing some minor deterioration, to bridges in which all primary structural elements are sound but may have minor section loss, cracking, spalling or scour; and may include minor erosion on bridge piers.

POOR – There are five categories of poor bridges:

  • Poor – Advanced corrosion, deterioration, cracking or chipping. Also significant erosion of concrete bridge condition piers.
  • Serious – Loss of section, deterioration, spalling or scour have seriously affected primary structural components. Local failures are possible. Fatigue cracks in steel or shear cracks in concrete may be present.
  • Critical – Advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present or scour may have removed substructure support. Unless closely monitored, it may be necessary to close the bridge until corrective action is taken.
  • Imminent Failure – Major deterioration or section loss present in critical structural components, or obvious loss present in critical structural components, or obvious vertical or horizontal movement affecting structural stability. Bridge is closed to traffic, but corrective action may be sufficient to put the bridge back in light service.
  • Failed condition – Bridge is out of service and beyond corrective action.

Ranking the States

All data come from the Federal Highway Administration’s online National Bridge Inventory as reported by June 15, 2024. It was compared with data reported as of June 15, 2023.

States with the lowest percentage of bridges rated poor

  1. Nevada – At 1.14% with only 24 bridges out of 2,099 rated in poor condition, Nevada came in first in this category, displacing Arizona from its lead position in last year’s report. In 2023, 1.20% of Nevada’s 2,090 bridges were in poor condition.
  2. Arizona – With 8,573 bridges within its borders, just 1.15% in Arizona are rated in poor condition. However, this is slightly higher than the 1.11% Arizona reported in 2023.
