Mecklenburg-Vorpommern The Bundesstraße 191 or B 191 is a German federal road.

It begins in Celle at the B 3 and ends north of Plau am See, connecting to the B 103[1] at the new bypass.

One year later roadworks were completed as far as Lübz and, in 1936, the first road bridge over the Elbe was opened in Dömitz .

During the division of Germany it was interrupted at the Inner German Border where the Elbe bridge had been partly destroyed in an airstrike in April 1945.

The eastern section between Dömitz and Plau am See belonged to East Germany and was known as Fernverkehrsstraße 191 (abbr: F 191).
