Skanska and Strabag have completed tunnel boring on the Ulriken rail tunnel near Bergen in Norway after 21 months of tunnelling work.
Breakthrough of the tunnel boring machine – Ulrikke – was witnessed by almost 1,000 people and watched by many more live on local television networks.
The new 7.7km long rail tunnel will remove a major bottleneck on the rail network in Bergen. The new tunnel runs parallel to an existing single track tunnel, which currently holds the title of the busiest single track rail route in Europe.
Speaking about the success of the breakthrough, Skanska project manager Tobias Andersson said: “This is what we have been looking forward to the whole 21 months of tunneling. We have done what we set out to do.”
