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.
