What percentage of bridges is estimated to be functionally obsolete according to the Bureau of Transportation statistics?

The statistic indicating that approximately 13% of bridges are deemed functionally obsolete is derived from assessments conducted by the Bureau of Transportation Statistics. A bridge is classified as functionally obsolete when it does not meet current design standards and is inadequate for modern traffic demands, even if it remains structurally sound. This classification highlights issues such as inadequate lane widths, low vertical clearances, or insufficient load capacity that fail to meet contemporary usage standards.

Understanding this figure is crucial for identifying infrastructure needs and prioritizing funding for repairs and upgrades. It emphasizes the importance of regularly updating and maintaining infrastructure to ensure safety and efficiency in transportation networks.

While other percentages may relate to different contexts or criteria, the estimate of 13% accurately reflects a specific assessment of bridges that are functionally obsolete, underscoring the need for ongoing infrastructure improvements in the transportation sector.
