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.
You may use tunnel=flooded to map larger and longer tunnels used to channelise any fluid.
How to Map
Apply to the section of covered waterway. Use the tag layer=* as usual for tunnels.
See Key:tunnel for a description of the preferred way of connecting culvert waterways to adjoining waterway sections.
Possible tagging mistakes
- culvert=yes ‒ The culvert=yes syntax is deprecated (since 2010) due to ambiguity.[1] Please use tunnel=culvert instead. (While technically sound there is no use of culvert=no as of April, 2015, so avoid it altogether.)
Automated edits are strongly discouraged unless you really know what you are doing!
