```C M,

I think that one of the things that defines a culvert is whether it has an
invert that is integral with the structure and that the superstructure is
also integral with the vertical supports.  Typically, earth fill is on top of
a culvert, whereas a bridge usually has its top surface as the riding surface.

The structure that you describe would be called (here in Arizona) a 10-barrel
box culvert.
