Norway's Rogfast Tunnel: The World's Longest Underwater Road!

Dive into the incredible engineering feat that is Norway's Rogfast tunnel! This video explores the 17-mile long underwater tunnel, complete with an undersea roundabout. Discover the challenges of building at a depth of nearly a quarter mile beneath the North Sea, and see how Norway is setting a new standard for underwater construction. Learn about the two-lane tunnels, the innovative roundabout design, and the impressive pressure resistance. Forget the Holland Tunnel, this is next-level engineering! Key points: - Rogfast tunnel length: 17 miles - Features an undersea roundabout - Depth: nearly a quarter mile - Construction challenges and pressure - Comparison to other tunnels
