• A. True
• B. False
• C. Not defined
• D. Only used for new bridges

Answer: (A)

Special inspection is a type of inspection used when a bridge is undergoing unusual or critical work, materials, or conditions that require closer oversight than routine checks. In many agencies, this is described as interim inspection because it is temporary and tied to a specific construction or modification stage, ensuring safety while work is in progress and before returning to normal inspection cycles. This approach covers activities like rehabilitation, retrofitting, or installing new components, where temporary conditions or risks exist.

So, the statement is correct: special inspection is also known as interim inspection. It isn’t restricted to new bridges; it also applies during rehabilitation or major alterations.
