The section between Pforzheim and Nagold is known as Nagoldtalstraße and from 1901 between Pforzheim and the Baden - Württemberg state border at Unterreichenbach was led as Baden state road 158 . Today's Bundesstraße 463 had different numbers before the introduction of the Reichsstraße network :

The plan is to relocate the B 463 in the city of Pforzheim and, as Pforzheim's west bypass, will in future lead traffic from the Nagold valley around the city center. The junction to the B 10 and A 8 was already completed in June 2012. On November 20, 2015, the ground-breaking ceremony took place for the extension to Landesstrasse 562 (Dietlinger Strasse).
