NHI Bridge Safety Inspection Exam 2025 – Complete Midterm Practice for In-Service Bridges

Assessing the performance of an in-service bridge focuses on identifying conditions that could impact its safety, functionality, and longevity. Major defects stand out as significant concerns because they often indicate critical issues that could compromise structural integrity. These defects may involve severe cracks, corrosion of critical load-bearing components, or significant misalignments, which could lead to catastrophic failure if not addressed promptly.

Furthermore, while minor wear and tear is normal for any structure and can typically be managed with regular maintenance, it is the major defects that pose the greatest risk. Routine maintenance and temporary repairs may help the bridge function in the short term, but they do not address the underlying structural problems. Thus, identifying and rectifying major defects is crucial to ensuring the bridge remains safe for public use and can withstand the loads it is designed to carry.
