What is the name of the federal controlled-access highway system in Germany that is part of the Cologne Beltway?
Cologne Beltway The Cologne Beltway (German:"Kölner Autobahnring") is the collective term for the Autobahns encircling Cologne. It consists of the Bundesautobahn 1, the Bundesautobahn 3 and the Bundesautobahn 4. The beltway handles one of the highest traffic volumes in Germany.
Bundesstraße 186 The Bundesstraße 186 is a German federal highway. Originally, this road ran from Köthen to Bitterfeld. During East German rule, the number 186 was reassigned to a loop running around the city of Leipzig. Due to brown coal mining, two strips of road in the north (between Schkeuditz and Taucha) and the south (between Zwenkau and Markkleeberg) had to be demolished, splitting up the road into two segments.
