Which field focuses on the surveying, plan, design, analysis, construction, management, and maintenance of bridges that support or resist loads?

• A. Civil Engineering
• B. Bridge Engineering
• C. Structural Engineering
• D. Transportation Engineering

Answer: (B)

Focusing on the complete lifecycle of bridges—surveying, planning, design, analysis, construction, management, and maintenance—defines Bridge Engineering. This specialization is dedicated specifically to bridges and how they are conceived, built, and kept safe over time, ensuring they can carry and resist the loads they encounter.

Civil Engineering is the broad umbrella that covers many types of infrastructure, while Structural Engineering studies how individual structures respond to loads, not necessarily the full bridge project lifecycle. Transportation Engineering deals with planning and operates the movement of people and goods, rather than the detailed design and maintenance of bridges themselves.

So, the field that precisely matches the description is Bridge Engineering.
