Is it accurate that 12.4% of bridges are considered structurally obsolete?

Answer: A — True

The statement that 12.4% of bridges are considered structurally obsolete is considered accurate based on reports and assessments from various transportation agencies. When a bridge is classified as structurally obsolete, it means that it no longer meets the current standards for design or safety, though it may still be safe for use. This statistic is significant because it highlights ongoing challenges in infrastructure maintenance and funding. Understanding this percentage is important for public safety and transportation policy, as it emphasizes the need for investment in repairs and upgrades to ensure that infrastructure can support modern traffic loads and safety requirements. Since the number is derived from comprehensive evaluations of bridges across an entire network, it is a relevant figure in discussions about infrastructure and transportation planning.
