Which term describes a bridge that can be opened for water traffic?

• A. Bridge
• B. Overpass
• C. Drawbridge
• D. Tunnel

Answer: (C)

Movable bridges that open to let ships pass have a section that can be raised or swung out of the way. Drawbridge is the term for that type of bridge, usually using counterweights or motors to lift the span so water traffic can go through. A general bridge isn’t necessarily movable; an overpass is just a bridge over another road and isn’t designed to open for ships; a tunnel goes underground or underwater and doesn’t open to water traffic. So the term that describes a bridge opened for water traffic is drawbridge.
