The Bundesstraße 8 (abbr. B8) is a German federal highway in southwestern Germany of great historical importance. It has existed since the 9th century, known then as Via Publica, and until recent times was a key trade route linking the towns of Brussels, Duisburg, Cologne, Frankfurt, Würzburg, Nuremberg, Regensburg and Passau. Today it has been replaced as a main route by the A3 motorway which runs parallel to it. From Wikipedia
