When Nienburg was disbanded on 1 January 2010, it was incorporated into Bernburg, along with the communities of Baalberge, Biendorf, Gröna, Peißen, Poley, and Preußlitz.

Much of the surrounding area is gently rolling farmland, broken up only by about 114 square kilometres (44 sq mi) of woods dividing Crüchern from Wohlsdorf.

The river Ziethe forms a border between the Wohlsdorf subdistrict and the village of Mölz, a sub-district of Kleinpaschleben.

It bends again southeasterly and around the western edge of Biendorf, another village-sub-district of Bradenburg on the southern border of Wohlsdorf.

West of L149, B185 continues for 14 kilometres (8.7 mi) towards Bernburg, passing the Latdorf/Dröbel landfill between Latdorf and Dröbel until it meets international European route E49 and becomes B6.
