   Similarly, I have been combining sidewalks with roads where there is 
no separation.   But when there is a small grass separation from the 
roadway, they are drawn separately.  For those cases, it is usually 
allowed to cross the grassy separation and the road to get to the 
opposite sidewalk.

   Throwing out the R word here - what about a relation that defines 
which disconnected ways could be walked to or across from any point on a 
current way?   That would also include the road since there would be no 
barrier.
