The BundesstraÃÂe 185 (abbreviation: B 185) is a German federal road or BundesstraÃÂe in the state of Saxony-Anhalt. It runs from east to west connecting the town of Dessau-RoÃÂlau with the Harz mountain region. Between Kleinpaschleben and Dessau-RoÃÂlau the B 185 is part of the German Avenue Road.
The present BundesstraÃÂe 185 links the most important Residenz towns of the former Principality of Anhalt. Only the section between Aschersleben and Ermsleben lay on Prussian territory. This section was known as Prussian State Road No. 90a (preuÃÂische Staatschaussee Nr. 90a) which was completed in 1842.
The 64.7 km long ReichsstraÃÂe 185 between Dessau and Aschersleben was built around 1937. In the 1960s the road was extended as far as Alexisbad in the Harz mountains.
