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.
