Thanks for the link regarding the current construction site and for updating the conditional restriction (which has been disregarded, not only by routers *sigh*).
  The website says "zumindest bis Weihnachten", i.e. "at least ...".
  Anyway, I do not really see the need to close this note (is this what you meant?) until the road is really open again, as this is an open issue and changes may still happen.
