World Record in the Solbakk Tunnel (Norway)

Never before has a road tunnel reached this depth below sea level. Nearly two and a half years after the beginning of the excavation, have 4.4 kilometers of the total of 7.9 kilometers of the tunnel tubes been blasted out.​

The interior finishing and road construction, which are executed parallel to the excavation work, are on schedule. Until now, also 2 kilometers of the asphalted road have been completed.

The first 500m of the inner shell and sealing (membrane) have been installed, and the first block of 200 m is final-shotcreted.
