What is the term for a construction made for carrying the road traffic or other moving loads in order to pass through an obstacle or other constructions?

• A. Bridge
• B. Viaduct
• C. Fly-over/Over-Bridge
• D. Substructure

Answer: (A)

The essential idea is that this structure is the crossing built to carry traffic over an obstacle. The broad term for any such crossing is a bridge, which covers all forms that carry loads across gaps like rivers, valleys, or other barriers. A viaduct is typically a long sequence of spans over a wide area and may cross multiple obstacles, so it’s a subtype of bridge rather than the generic term. A flyover or over-bridge refers to a specific elevated bridge designed to let one road pass over another. Substructure describes the foundations and supporting parts, not the whole crossing. So the general term that fits any crossing over an obstacle is bridge.
