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.

Typical culvert is a pipe buried under the road. Very large culverts may be hard to distinguish from bridges. Culverts commonly carry waterway=stream, waterway=drain, and waterway=ditch, but there are also large culverts carrying waterway=river.

tunnel=flooded may be used to map larger and longer tunnels used to channelise any fluid.

How to map

Tag the section of covered waterway, including layer=* as usual for tunnels.

culvert=inverted_siphon may be added for sections of a waterway diving under another waterway.

See tunnel=* for a description of the preferred way of connecting culvert waterways to adjoining waterway sections.
