Very cool, In Norway they are considering creating a floating tunnel that is held up with giant floating bois tederet to the ground because some places the sea is just to deep and steep. Anyway here is a video, dunno about current status: https://youtu.be/Gt1MDQHLjF8?t=26 https://youtu.be/Gt1MDQHLjF8?t=26
- andrew_ 5y agoThis would almost certainly require some advanced sea traffic mitigation. See the Sunshine Skyway Bridge Tragedy [1]. Even with openings for vessels, there's a real threat by large vessels. [1] https://en.m.wikipedia.org/wiki/Sunshine_Skyway_Bridge https://en.m.wikipedia.org/wiki/Sunshine_Skyway_Bridge
- CRConrad 5y ago> there's a real threat by large vessels. Which is a bit weird: Why have those pontoons on the surface in the first place? They could provide just as much buoyancy if they were tethered just above the tunnel itself, at a depth of some tens of meters. Or below it, pushing upwards in stead of pulling. (This would also avoid any potential problems with ice dragging them sideways in the winter.)
