 :Hi. I've been busy, but haven't forgotten. Let me start by saying your effort is appreciated. 
 :The primary issue is that what streets a road crosses (except for in some cases perhaps one or two particularly notable ones) might not be encyclopedic information. Having said that, it might be notable in this case as they're the historical roads linking Brussels to the rest of Belgium. In the R21's case, the cross-streets probably aren't notable enough. 
 :In this case, at least, I would be in favour of moving the infobox down to the portion of the article where the roads are discussed. That way the labels are more clear. What do you think? 
 :And yes, I was sloppy, the info I deleted was not already in the article. My bad. ''''''  "
