text: OK, this looks new, last time I was there (sheesh.. is it more than a year already) there was no connection of this track to the Okrifteler Straße. I remember that I had to go towards the parking lot to reach the street (bike path) because there was (and it looks like there still is but now with an opening for this track towards the street) a fence between the track and the street/bike path, to be able to get to the other side of the airport to ride my bike to Kelsterbach.
  
  Btw, this bike path was for travelling in both directions when I was there. But looking at it in this picture it seems to have been changed from a separate path to a lane so it could be oneway now.
