"causeway"的定义和意义

What is a "causeway"?

A causeway is a raised road or path that is built across low or wet ground, often over water or marshy areas. It is designed to provide a stable route for vehicles or pedestrians, preventing them from sinking into soft or flooded terrain. Causeways are typically made with solid materials like stone or earth and are often found in areas where natural features make regular roads difficult to build.
