text: I assume that in all parts of Austria many people refer to the nearest Bundesstrasse as only "Bundesstrasse". Only "Bundesstrasse" is very generic, I wouldn't add it. (We also don't add alt_name="Autobahn" to every motorway.)
  
  But note that in some villages (for example in Roethis), the part of the L190 that goes through is called "Bundesstrasse", which is then used as the value for the name-tag.
