Bözberg Tunnel-TBM should start drive in May

Swiss Railways (SBB) plan to provide a 4 m corridor along the entire Gotthard axis by 2020 in order to be able to transport semi-trailer (articulated) trucks with a height of 4 m by rail. The new building of the Bözberg Tunnel in the canton Aargau is the largest individual project with an investment sum of about 350 million Swiss francs. In addition to the existing two-track Bözberg Tunnel, a new two-track tunnel almost 2.7 km long is being built parallel to the existing tunnel. Drill and blast tunnelling started in autumn 2016. Working three shifts, a distance of 168 m has been conventionally excavated in soft ground. Drill and blast tunnelling started in autumn 2016. Working three shifts, a distance of 168 m has been conventionally excavated in soft ground.

U5 Tunnel Berlin: Breakthrough to Brandenburg Gate Metro Station

The U5 project in Berlin is one of the most important ongoing infrastructural schemes in Europe for Implenia. On March 22, 2017 the final concrete wall separating the new U5 tunnel from the Brandenburg Gate Metro Station was penetrated. In this way, the gap between U55 (Central Station–Brandenburg Gate) and the traditional U5 (Alexanderplatz–Hönow) has been closed and the tunnel roughwork has been completed, which commenced with the start-up of the “Bärlinde” tunnel boring machine (TBM) back in 2013.

World Tunnel Congress 2017: Tunnelling in Norway

High mountains, long fjords and steep valleys. A demanding landscape and tough climate with abundant precipitation meaning infrastructure construction is a severe challenge in Norway, host of the World Tunnel Congress 2017 from June 9 to June 15 in Bergen. The especially demanding circumstances became all the more obvious as roads and railways started to replace the sea routes as the standard means of travel in Norway. The first Norwegian road tunnel was built in 1884. The great breakthrough for traffic tunnelling came with the construction of the Bergen Railway in 1909: 182 tunnels were constructed as part of this first rail connection between east and west of Norway. Today Norway has more than 1800 road and rail tunnels, whose total length is well over 1000 km.
