The B 214 then continues, crossing the Damme Hills and runs north of the Dümmer lake through numerous boggy (moor) areas.

The metalled, man-made road (Chaussee) between Brunswick and Celle was built from 1804 to 1815 and called Celler Straße.

The B 214 used to run within Brunswick past its present end at Amalienplatz down Celler Straße and the western arm of the Oker and the Radeklint to the city centre.

Since the Reichsstraße times many of the B 214's former routes through villages and towns have been replaced by ring road section, the last (in 2008) being the bypass around Diepholz.

The route from Nienburg as far as the crossing with the B 3 near Celle was originally to have been upgraded to form part of the scrapped A 32 autobahn project.
