Norway: Bjønnås twin-tube tunnel completed

Congratulations on this latest milestone. Now it's time for the paving, roadworks and tunnel electromechanical systems installation teams.

As a reminder, this motorway project is one of the most important in Norway, linking two major urban centers, Oslo and Kristiansand. The section, which will link the towns of Langangen and Rugtvedt, is 17 kilometers long and includes the construction of several structures such as the Bjønnås twin-tube tunnel (2 x 2.5 km) and the Grenland tunnel (5.1 km).
