Implenia have secured a EUR98.50 million (SEK1 billion) Stockholm Region contract for construction of the new underground station Sofia on the metro Blue line in Stockholm. The contract includes elevator shafts, two single-track tunnels for the subway and a parallel service tunnel. This requires the construction of 4.6 km of drill and blast tunnels. Stockholm’s blue subway line is being extended from the centrally located Kungstradgarden to Nacka in the southeast of the Swedish capital as well as to Hammarby Sjöstad in the south. The new Sofia metro station, located close to Stigbergsparken, will become an important hub for travellers. Located approximately 100 m below ground, it will be one of the deepest underground stations in the world. Eight large high-speed elevators will take commuters to and from the platforms in about 30 seconds. Visit https://implenia.com/en/ . 18/21.
