a rivier / canal "runs over" an aqueduct.
Sufficiently large aqueducts may also be usable by ships.
They are a kind of viaduct, carrying water instead of a road etc. While a road
bridge often carries the road at a more elevated level than the rest of the
road, such a variation of height is not possible for an aqueduct, of course.
In the Netherlands there are several (modern) aqueducts, i.e.:
* Aqueduct under the Vliet/Leidschendam-Voorburg
* Aqueduct Veluwemeer/Harderwijk
* Aqueduct Ringvaart Haarlemmermeer.
