Which bridge is designed solely for pedestrians?

• A. Railway Bridge
• B. Pedestrian Bridge
• C. Airport Runway Bridge
• D. Aqueduct Bridge

Answer: (B)

The main idea here is that bridges are built for the specific users they must carry. A pedestrian bridge is designed specifically for people on foot, with a deck and safety features sized for pedestrians and no requirement to support vehicles or trains. That’s why this option is the best choice—the structure’s sole purpose is to enable people to cross safely on foot.

The other options serve different roles: a railway bridge must handle heavy, dynamic train loads; an aqueduct bridge is built to carry water across a gap (its primary function is conveying water, not pedestrian traffic); an airport-related bridge would be part of airport infrastructure and designed for specific aircraft-related or service operations, not for pedestrians alone.
