This is how I understand "culvert", from New Zealand. Although I've rarely heard "sewer tunnel", it's just "sewer".<br><br>Tim.<br><br><div class="gmail_quote">On 27 August 2010 06:29, John F. Eldredge <span dir="ltr"><<a href="mailto:john@jfeldredge.com">john@jfeldredge.com</a>></span> wrote:<br>

"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.<br>

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