E-mail tobias.kednert@mk.stockholm.se or ake.stiberg@carlbro.se 28/06.Details are available about the construction of the Skanstull-Solberga cable tunnel in Stockholm. The main tunnel includes sections of 18.3 sq m for a 5,560 m distance (height 5 m) and 20.3 sq m for a 780 m distance (height 5.5 m). For both tunnels the width is 4 m. There are also three work tunnels of 27.4 sq m with a total distance of 780 m and five vertical shafts for cables, ventilation and stairs. They are deep tunnels in rock (mainly gneiss) below the groundwater level. The new tunnel is not allowed to cause sinking of the groundwater level due to existing buildings at the surface and crossing tunnels above the new tunnel. The tunnel is planned to be built by conventional driving by jumbo and explosives in full section, but alternative solutions may be accepted. To stop groundwater, mainly drilling and concrete injection is planned. To support the rock, mainly bolts and shotcrete with and without fibres will be used. Concrete formwork at the tunnel ends. Steel construction in the five shafts. Small rooms for technical equipment are required underground. An invitation to tender is under way, for contact award in December 2006. Construction to start immediately after for end on 31st March, 2010.

Svenska Kraftnaet the Swedish National Grid a joint venture between Implenia (50%)/Hochtief (50%) (for 4 years) secured the  Eur90 million contract to build the Anneberg-Skanstull tunnel in Stockholm.

As the second of four phases in the City Link project, the Anneberg-Skanstull tunnel will help improve electricity supply in the Greater Stockholm region. With a length of around 14 km and a diameter of 5 m, the tunnel is being built around 50 - 100 m below the Swedish capital using a tunnel boring machine. The project also includes six ventilation shafts, elevator systems and the construction of technical buildings for electrical equipment near Anneberg and around the shafts. Completion is scheduled for 2024. The aim of the City Link project is to connect the north (Upplands Väsby) and the south (Huddinge) of Stockholm with a new electricity supply.
