Osmarender does a pretty good job of those bridges:
http://www.openstreetmap.org/?lat=27.95907&lon=-82.53907&zoom=17&layers=0B00FTF
Notice how it combines the two ways heading south into one bridge even
without any additional information besides the fact that the two ways are
close together.

Mapnik, not as much:
http://www.openstreetmap.org/?lat=27.95873&lon=-82.53908&zoom=17&layers=B000FTF

I don't believe either renderer factors in width or lane information, but I
haven't added that (unfortunately, I apparently can't use the image from
mytbi as a source for the number of lanes, because it isn't public domain).
Add in lane information, and width information (which is already supported
by the current api), and we're getting close to what I see as ideal.
