On Tuesday the 29th of August Ulrikke will see daylight on the Bergen side of the new railway tunnel between Arna and Bergen.
When we were visiting Wednesday morning, there were only 110 meter rock left before breaking through on the Bergen side of the tunnel. It is an impressive machinery that has drilled through Ulriken. The TBM is 152 meter long and has devices for bolting, grouting and spraying concrete. The TBM’s diameter is 9.3 meter.
Thanks to Guro Isachsen and Kåre Bjørn Solhaug for good guiding!
