Changes

From the center walk to the ''Adenauerallee'' which leads into the ''Friedrich-Ebert-Allee'', you are already on the B9, you can hitch from every possible spot here, where a car is able to stop. You won't get very long rides, but if you want to go to Koblenz or Mainz, it is the better choice to hitch this [[national road]]. Aware, the road is mostly two-laned, so make sure you will get dropped in a [[Where to hitchhike|save spot]] (Remagen, or Bad Breisig) where the road is interrupted by traffic lights and where are bus stops where you can hitch on further.

In this direction you also need to get on the A3 (see South towards Frankfurt above). You can use both options - the A3 petrol station has stations on both sides which are connected via a pedestrian bridge, and from the station at Augustinerstrasse you can get north and south.

Mind that Koln (Cologne) is part of the same metropole area as Bonn and is connected via public transportation. Once on A3, ask for lifts to Oberhausen, because getting to Koln itself is of no use.
