  • Role: subject
  • In the video: The video explains how the Fehmarn Belt between Germany and Denmark forces a 500 km detour on the Scan-Med corridor. A bridge was ruled out by wind and depth and a bored tunnel by cost, so a 18 km immersed tunnel is being built, due to open in 2029.
  • Why it matters: The strait and its planned tunnel are the whole subject of the video.
