What term refers to a raised road built across water or low ground?

The term "causeway" refers specifically to a raised road or track built across water or low-lying land. It often serves as a means to connect two points that would otherwise be separated by a body of water or marshy ground. Causeways are typically constructed with materials that allow them to withstand the pressures of water and sediment, making them a vital infrastructure solution in areas where traditional roads would be impractical. This distinguishes them from other terms like "bridge," which primarily refers to structures designed to span a physical obstacle without covering it, or "dam," which serves a different purpose of holding back water. A "pathway" is more general and does not imply the raised or constructed aspect necessary for crossing water or low ground.
