B7) is a German federal highway (Bundesstraße) that stretches from the Dutch border at Venlo in the West to Rochlitz near Chemnitz in the East.

Because of its western origin some stretches of the B 7 are designated as "Holländische Straße" (Dutch Road), e.g., in Kassel and Calden.

The segment between Wuppertal and Hagen was constructed in 1788 (237 years ago) (1788), making it one of the oldest roads in western Germany.

The original plan marked Dresden as he eastern terminus, however this portion was completed during the Third Reich and called the Bundesstraße 173.

Environmental concerns have been raised about the project, as the autobahn is proposed to run through the national park Meißner-Kaufunger Wald.
