I think the best would be to use  more than one way for diffrent thinks:

Example:

A -> B -> C -> D -> E

Way one:
A->E
name=Kings Road
highway=primary

Way two:
C->D
bridge=yes

Way three:
A->D
route=bus
name=bus route 24
timetable=http://www.bus-okay.example/route24

Way four:
D->E
oneway=yes


This is currently not supported by the tools, so at the monent I also use 
tagging like this:

A->C
name=Kings Road
highway=primary
route=bus
route_name=bus route 24
timetable=http://www.bus-okay.example/route24

C->D
name=Kings Road
highway=primary
route=bus
route_name=bus route 24
timetable=http://www.bus-okay.example/route24
bridge=yes

D->E
name=Kings Road
highway=primary
oneway=yes

I realy dont know if we should need a superway. Example:a bus don't alway goes 
along the whole street, but only a part of it.
