Which term describes a road feature that bridges a gap and carries traffic over an obstacle?

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

Answer: (A)

A bridge is the term that describes a road feature built to span a gap or obstacle and carry traffic over it. Its purpose is to connect the two sides so vehicles can pass without descending into the gap, whether that gap is a river, valley, or roadway cut. The other options describe different ways to get from one side to the other: an underpass or tunnel goes beneath the obstacle rather than over it, which is why they don’t fit the idea of crossing over the gap. A drawbridge is a specific type of bridge that can be lifted to allow ships to pass; while it is still a bridge, the question points to the general crossing structure, for which the broad term is simply bridge.
