text: these two are definite bridges; the culvert (tunnel) looks different and there is one upstream not far from the fork.  i'd open a note to point it out, but that i can't do from within my chosen editor.

  and no, i won't make changes - i am an armhair mapper and rather i prefer to offer advice to local mappers based on my observations and so-called ``experience''.
  
  i will however point out errors, such as your assumption that there must be a tunnel, rather than the correct bridge here.  (this is a worry that has been expressed in mailing lists, is that incorrect info will be added to quiet the warnings now spewed by iD, by inexperienced but well-meaning mappers.)
  
  again, thanks for not doing so, but opening the notes to get feedback.
