The tour from Tuebingen to Mechelen.

The tour was exhausting, because there were a lot of road work with speed limits. And a lot of them caused traffic jams. My plan was to arrive Mechelen in six hours, but I needed eight and a half from Tübingen to Mechelen. The route ran over Stuttgart, Karlsruhe, Aachen, Brüssel. Two things confused me. First, the main classification for the highways in Belgium is not A-and-a-number, but E-and-a-number. Maybe it is only a small difference, but it might be time consuming, because the larger signs use all an E instead of an A. Second, there exists also a small town Machelen on the same route. Do not use that gateway, that is simply not correct.
