According to transportation statistics, what percentage of all bridges are considered functionally obsolete?

The correct answer is that approximately 13% of all bridges are classified as functionally obsolete. This classification means that while the bridges are still standing and safe to use, they do not meet current design standards or may be inadequate for the volume and type of traffic they now support. These bridges can experience increased wear and tear, leading to potential concerns regarding capacity and safety.

Understanding the percentage of functionally obsolete bridges is crucial for transportation planning and infrastructure investment decisions. It highlights the need for regular assessments and potential upgrades or replacements to ensure safe and efficient transport networks. This statistic reflects ongoing challenges in addressing the aging infrastructure within the transportation system.
