[OSM-talk] Culvert and average contributor

[John F. Eldredge]

The term "culvert" is also standard usage in American English.  "Tunnel" is generally used to mean an underground passageway large enough for a person to walk through, if not larger.  Also, the default assumption is that a tunnel is not intended for drainage, unless there is a longer phrase such as "sewer tunnel".  A "culvert" refers to a tube or pipe under a roadway or other raised area, meant to carry surface-water runoff.  Some are large enough to walk through, but most aren't.  Usually they extend only for a short distance, such as the width of a roadway.  "Covered" does not indicate the size of a passageway, nor does it indicate the intended purpose of the passageway.

It's in very frequent use among boaters on the British canals, largely
because the ruddy things keep collapsing and taking the canal with them.
