M3 (Copenhagen)

The City Circle Line (Danish: Cityringen) or M3 is a future expansion of the Copenhagen Metro. Plans for its construction were approved by the Danish Parliament on 1 June 2007. Preferred bidders were announced in November 2010. The total cost was estimated at 15 billion kroner but had risen to 21.3 billion kroner when the contractors were announced.

The 15.5 km City Circle Line will serve 17 stations. It will intersect the M1 and M2 lines at Kongens Nytorv and Frederiksberg stations, and suburban train services at København H, Østerport and Nørrebro. It will extend the Metro network to the Nørrebro and Østerbro areas and København H (the Copenhagen central station).

Initially, two possible routes were considered, after an even bigger screening of ideas. In December 2005, the Copenhagen and Frederiksberg municipalities selected the Frederiksberg route. The purpose is to cover areas not yet served by S-trains or the Metro.

The finished line will influence much of Copenhagen's current transport network. The transit agency Movia projects up to 34 million passengers will switch from buses to the Metro annually.

The excavation earth is being used to fill the Nordhavn reclamation project in Øresund.

Stations are listed counterclockwise, beginning in the southeast.

These new stations will have a similar design and structure to those of the current Metro, but with more varied materials and colors, making the individual station more recognisable.
