text: interestingly enough, as you were resolving this, i was investigating on osm.org proper, to see if the layers (cycle, transport) known to lag behind the standard rendering, were still lacking.
  
  it looks like transport does not render this, only the route relations, or i don't remember how an autobahn would be rendered.
  
  some render styles will show updates quickly; osm.de is independent of osm.org and the maintainers of that site would need to make whatever adjustments are needed for more frequent updates without negatively affecting performance.
