|Route outline (key)|
The Berliner Ring also known as the A10 is Berlin's version of the M25. At 195 km (121.2 miles) it is slightly longer than the M25. The eastern and southern section of the ring road which comprises a length of 129 km were built within 5 years in the 1930s. Yet, it took another 50 years to complete the ring road. In 1979 the western section from Potsdam-Nord to Abzweig Rostock opened for traffic. The latter junction is now known as Dreieck Havelland.
After the German reunification the A10 was part of improvement scheme which implied the widening of the southern and eastern section of the ring as well as improvements of major junctions. The ring road is therefore now of a D3M standard throughout its south-eastern half from Kreuz Barnim to Dreieck Werder.
The widening of the northern part to D3M is proposed and partly under construction.
