Cologne Beltway - "Second Beltway"

"Second Beltway"

In the 1970s, a second beltway around Cologne was considered, incorporating existing Autobahns, instead of expanding the first one to more lanes. An expansion of the old beltway was considered as too expensive because of the large number of bridges. It was planned to incorporate some of Cologne's other Autobahns into this second Autobahnring. These plans were however never implemented.
