not so true everywhere: in mountain areas rivers are usually at the
bottom of valleys, and I've seen many small rivers covered and
practically brought underground in urban areas.

as a guideline, i usually mark the road +1 if it rises to become a
bridge, but 0 and the river -1 if the river is lower than the ground
where most of the road is
