actually the comment above is refering to bridge=no >> aqueduct >> 1?084 0.06% prefer historic=aqueduct for historic aqueducts (also >> fragments) and would rather introduce a tag similar to "power" for >> water if I wanted to map modern aqueducts.

An aqueduct can be on the ground, on a wall, below ground, and also span over something with a bridge. bridge=aqueduct is therefor not a suitable tag for aqueducts, but it could be OK in some cases. In the end if you already use a different tag to say it is an aqueduct you just as well use bridge=yes for these parts. cheers, Martin _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
