Which structure is designed to move water from one side of a road to the other, allowing the water to flow on the road surface?

Drainage under a road uses structures that carry water from one side to the other. A culvert is a pipe or tunnel placed beneath the roadway to convey water across the road, letting runoff pass beneath and preventing water from pooling on the surface. Cupola is simply a dome on top of a building, not part of road drainage. Crowning describes shaping the road so water runs off to the sides along the surface rather than under the road. Crown Class isn’t a drainage device and doesn’t move water across the road. So the culvert best fits the function described.
