Which of the following is a primary reason for performing routine bridge inspections?

Performing routine bridge inspections is crucial primarily to identify any potential safety hazards. This is because the primary goal of inspections is to ensure the safety of the traveling public and to maintain the structural integrity of the bridge. Inspections help in detecting issues such as cracks, corrosion, or structural weaknesses that could lead to failure or unsafe conditions if not addressed promptly. By identifying these hazards early, inspectors can recommend repairs or maintenance actions that can prevent accidents, ensuring the bridge remains safe for use.

While assessing user satisfaction, ensuring compliance with design standards, and tracking environmental changes are important considerations in bridge management, they do not directly focus on the immediate safety implications that routine inspections aim to address. Ensuring that bridges are free of safety hazards is paramount, making it the most critical reason for conducting these inspections.
