Raststatte Langen-Bergheim on A45 towards Siegen/Dortmund. Not the most frequented highway, so it might take longer. Most is long distance traffic though.

Good place to go to the south. Try to find a car wich go in direction Siegen (A1-A45) to pass Dortmund.

I write this for the other side of the road. Easy for hitching south Frankfurt, Darmstadt, Karlsruhe. Harder to hitch to the West - Koblenz Trier and Average for hitching to Siegen or Cologne (North West)
