To be the first capital city to be CO2-neutral by 2025 and at the same time to meet the mobility needs of its residents and visitors: these are the goals Copenhagen has set itself, which is why it has decided to systematically expand the Copenhagen Metro.
The idea is that every Copenhagen resident should live no more than 600 meters from the nearest metro station. The connection to the newly developed urban areas of Nordhavn and Sydhavn has been in operation in the north of the city since 2020, and the southern extension will soon follow.
When the Copenhagen Metro's five stations on the new Sydhavn line open in 2024, residents and tourists will benefit from a big boost in public transport mobility. To achieve this, quite a bit of earth is being moved underneath the Danish capital: two tunnel boring machines are digging the two parallel tubes, each almost 4.5 kilometers long. A whopping 5,700 rings line the tunnel tubes, with the rings in turn consisting of more than 34,000 concrete segments known as tubbings. In addition to the five new stations, which are being built at depths of 17 and 24 meters, two crossing structures, where trains change tracks, complete the underground connections.
Passengers can also look forward to underground artworks specially commissioned for each station and fully integrated into the architecture of the stations. A major challenge-even for absolute construction professionals like HOCHTIEF's employees. Admittedly, the creations do not change the way tunnels and stations are built or their functionality. But as HOCHTIEF coordinator Dieter Schmitt tells us, there is a lot to consider (see portrait on Map 2).
