Questions & Answers

Q: What is the goal of Norway's coastal highway project?

The goal is to improve accessibility to services and labor markets in Norway's western regions by eliminating the need for ferry services through the construction of bridges and tunnels.

Q: What is the Rugfast project?

The Rugfast project involves the construction of a 27-kilometer undersea tunnel, making it the world's deepest and longest undersea road tunnel. It aims to link the E39 highway between Stavanger and Halkerson.

Q: How is Norway planning to cross the challenging Burner Fjord?

Two proposals have been put forward, including a floating bridge anchored to the shore at both ends and a submerged floating tunnel consisting of interconnected tubes tethered to the seabed.

Q: What challenges does the Songnifield crossing face?

The Songnifield crossing, considered the most complex and ambitious, must account for the wide and deep fjord, as well as the regular shipping traffic. Various options, including a suspension bridge, floating bridge, and submerged floating tunnel, are under consideration.

Summary & Key Takeaways

• Norway's E39 highway, stretching from Christensen to Trondheim, faces challenges due to the fjord network and reliance on ferry crossings. The new coastal highway project aims to eliminate ferry services by constructing bridges and tunnels.

• The Rugfast project involves the construction of a 27-kilometer undersea tunnel, reaching depths of up to 390 meters below sea level, making it the world's deepest and longest undersea road tunnel.

• Other innovative solutions, such as a floating bridge and a submerged floating tunnel, are being considered to overcome engineering challenges and cross challenging fjords.
