On 15 May the Danish Government reached an agreement with the Copenhagen City Council to construct two extensions of the city’s automated metro network. The extensions will reach Sydhavn and Nordhavn and will form branches of the city circle line (Cityringen), which is currently under construction.
The Cityringen will actually consist of two new lines, M3 and M4, and is due to open in 2018. The two extensions will be part of the M4 Line.
The extensions are to provide the Sydhavn and Nordhavn with a better transport connection with the city centre while relieving congestion of the metro.
The extension to Sydhavn is to have five stations, four of which underground, with a short section of surface line approaching the terminus Ny Ellebjerg, which is to provide a connection with the S-Bane suburban network. Through this extension, Copenhagen´s daily metro ridership is expected to increase by 43,000 passengers in 2023.
The second extension is to run on viaduct, running north to Nordhavn from the Cityring near Østerport.
Both extensions are planned to be fully operational in 2023.
