What percent of highway bridges are in poor condition?

In 2022, 5% of highway bridges were in poor condition. About 52% were fair, and roughly 43.1% were good.

The shares of bridges in poor condition decreased, and overall bridge conditions have improved over time. Look at 2000 as an example: That year, 9.8% of highway bridges were poor, 43.1% were fair, and 46.8% were good.

Highway bridges in poor condition decreased by 4.8% between 2000–2022, and bridges in fair condition increased by nearly 9%.
