Copenhagen Metro

Copenhagen, Denmark

In 2018 work began on Copenhagen’s metro line M4 Sydhavn. Since the opening of the subway line in mid-2024 the southern part of Copenhagen has been connected to the metro network. And this will make mobility with public transport even more convenient in the Danish capital.

The underground line has five new underground stations: Havneholmen, Enghave Brygge, Sluseholmen, Mozarts Plads and København Syd. The 4.5 kilometer long route in the South of the city extends the M4 line, whose northern end, the Nordhavn line, was also realized by HOCHTIEF (in a joint venture). In 2019 this section was handed over to the public. This means that in future it will be possible to travel with the underground from København Syd via a few stations of the urban ring to Orientkaj in Nordhavn.

The design-and-build project included construction of two 4.4 kilometer long tunnels using two earth-pressure-assisted tunnel boring machines (TBM) as well as construction of the five metro stations and two intersection structures. The project also included implementation of the operating technology, the interior work and the tunnel ventilation systems.

A special feature: each station was decorated by artists. Art is integrated into the architecture of the railway stations and is designed to transform them into special places. This certainly made the construction of the underground stations a special task.
