I would map them as three ways (warning, ASCII art below):

   *  |
   *  |
|  *  |
|  *  |
|  *  |
|  *  |

The "|" are the two sidewalks, the "*" is the main road.

Way marked with *:

  highway=residential (or whatever)

Ways marked with |:


In the example above I've also put a crossing, the "--x--" line. This would be
tagged as:

  crossing=* (depending whether it has traffic lights, is/isn't marked, [..])

For compatibility reasons with the current approach, I'd also tag the "x" node


The relation is optional, but if you wanted to, you can put the road marked with
"*" into an associatedStreet/street relation (with no role/"street" role), and
the sidewalks ("|") with role "sidewalk".
