A new cross country cycle route in Germany

Planning cycle routes in and around Heidelberg, Ludwigshafen and Mannheim is complicated, because the area is at the junction of three German provinces: Baden-Württemberg, Hessen and Rheinlandpfalz. I was therefore pleased to read that the Verband Region Rhein Neckar (VRRN - Regional planning organisation) had set up a new cycle route from Lamprecht west of Neustadt an der Weinstraße to Osterburken in the Odenwald through Ludwigshafen, Mannheim and Heidelberg. Its symbol is a yellow square. The route runs for 171km across the region. It is not a new route, but older routes have had additional signposting and have been incorporated in the route.
I was less than pleased to read that although the section east of Mannheim is finished, the western 55km will be finished next year in 2014. It would appear that road signposting is very tightly controlled in Rheinlandpfalz. It does not give one much hope of utilising the Dutch Knooppunt system in Germany. This is a real pity.
