[OSM-newbies] ways, bridges, and divided highways

[Jeffrey Martin]

I have a highway with two lanes in each direction. I made two parallel
paths of line segments with arrows going in opposite directions. I
combined the two parallel lines into a single way. Is this correct?

A road interrupted by a bridge is supposed to have a way on each side
of the bridge and a way for the bridge for a total of three. Why
shouldn't I have the road on either side of the bridge belong to the
same way? JOSM seems to let me do this.
