A culvert is a device used to channel water. It may be used to allow water to pass underneath a road, railway, or embankment for example. Culverts can be made of many different materials; steel, polyvinyl chloride (PVC) and concrete are the most common. Formerly, construction of stone culverts was common.
In some countries, the culvert structure is directly reused as a bridge in which case prefer the tag bridge=culvert. This tag does not apply for open-top culverts.
How to Map
Apply to the section of covered waterway. If the culvert is tall enough for pedestrians, add foot=yes. Use the tag layer=* as usual for tunnels.
Tagging controversy
tunnel=culvert is how some people want you to tag culverts. Before this wiki page was created the tagging of culverts was converging towards culvert=yes. Which was documented a few days before the creation of this page because that tag was actually in use.
Tagging statistics of the 19th of jan 2012:
- man_made=culvert: 1 uses (at least one).
- waterway=culvert: 107 uses.
- tunnel=culvert: 18611 uses.
- culvert=yes: 2239 uses.
- and many tunnel=yes for culverts before this proposal
