A culvert and a bridge are both structures used in civil engineering to facilitate the passage of water or traffic over obstacles such as rivers, streams, or roads. However, they differ in their design, function, and usage.

Culvert:

A culvert is a structure primarily designed to allow the passage of water underneath roads, railways, or embankments.

Typically, culverts are constructed with pipes, boxes, or arches and are buried underground or embedded within embankments.

Culverts are commonly used to manage the flow of water, prevent flooding, and maintain the integrity of roadways and railways by directing water away from the surface.

Bridge:

A bridge is a structure built to support the passage of traffic or pedestrians over water bodies, valleys, roads, or railways.

Bridges are typically constructed with beams, trusses, or arches and are elevated above the ground or water surface.

Bridges are used to provide a continuous pathway for vehicles, pedestrians, or trains across obstacles, allowing them to bypass natural or man-made barriers.

Objective Question:

Which of the following statements best describes the difference between a culvert and a bridge in civil engineering?

A) Culverts are used for pedestrian crossings, while bridges are used for vehicle traffic. B) Culverts are buried underground, while bridges are elevated above the ground or water surface. C) Culverts are only used for managing water flow, while bridges are used for transporting traffic or pedestrians. D) Culverts are made of steel, while bridges are made of concrete.
