Changes

U4 to Hütteldorf, exit Hadekgasse (left) and go left again, you are right on the main road leading out of vienna towards west (Linz, Salzburg, Munich...) There is a bus station which is quite a well known hitching spot. Change cars (if necessary) at the rest area in St. Pölten or Ansfelden. Alternativly, you can go over the motoway via the bridge. Turn right... you will find after ca. 1km the Autohof Wien.
