In a town which does not have underground storm water management, the
gutters at the side of the roads have to cross one of the roads at an
intersection so you have a half-elliptical shaped culvert which traffic
crosses, making a little ford. The wikipedia definition of culvert is
simply "A culvert is a device used to channel water." and these fit into
that definition.
Nice selective quoting. The full description is:
"A *culvert* is a device used to channel water. It may be used to allow
water to pass underneath a road <http://en.wikipedia.org/wiki/Road>,
railway <http://en.wikipedia.org/wiki/Railway>, or embankment
<http://en.wikipedia.org/wiki/Embankment_%28transportation%29> for
example. Culverts can be made of many different materials; steel
<http://en.wikipedia.org/wiki/Steel>, polyvinyl chloride
<http://en.wikipedia.org/wiki/Polyvinyl_chloride> (PVC) and concrete
<http://en.wikipedia.org/wiki/Concrete> are the most common. Formerly,
construction of stone culverts was common."
from http://en.wikipedia.org/wiki/Culvert
If the vehicle travels through the water, it's a ford, not a culvert --
the water is passing *over* the road, not under it.
