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.
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.
