Verkehrsmenge
Traffic volume on the Cologne Beltway has been increasing continuously since the 1950s. Almost all sections, with the exception of a short stretch on the A1 between "Kreuz Köln-West" and 1km north of "Köln-Lövenich" (Expansion in progress there, estimated completion December 2013), have since been expanded to three lanes in each direction, but since more than 180,000 cars use at least part of the Autobahnring every day, traffic jams are a frequent occurrence.
