Aqueduct (bridge)
Bridges for conveying water, called aqueducts or water bridges are constructed to convey  watercourses across gaps such as valleys or ravines. The term aqueduct may also be used to refer to the entire watercourse, as well as the bridge. Large navigable aqueducts are used as transport links for boats or ships. Aqueducts must span a crossing at the same level as the watercourses on each end. The word is derived from the Latin  ("water") and ("to lead"). A modern version of an aqueduct is a pipeline bridge.
