Submerged Floating Tunnel
A submerged floating tunnel (SFT), also known as submerged floating tube bridge (SFTB), suspended tunnel, or Archimedes bridge, is a proposed design for a tunnel that floats in water, supported by its buoyancy (specifically, by employing the hydrostatic thrust, or Archimedes' principle). The tube would be placed underwater, deep enough to avoid water traffic and weather, but not so deep that high water pressure needs to be dealt with; usually a depth of is sufficient. Cables either anchored to the seabed or to pontoons on the surface would prevent it from floating to the surface or submerging, respectively. Construction The concept of submerged floating tunnels is based on well-known technology applied to floating bridges and offshore structures, but the construction is mostly similar to that of immersed tunnels: After the tube is prefabricated in sections in a dry dock and the sections are moved to the site, one way is to first seal the sections; sink them into place, whi ...

Transatlantic Tunnel
A transatlantic tunnel is a theoretical tunnel that would span the Atlantic Ocean between North America and Europe possibly for such purposes as mass transit. Some proposals envision technologically advanced trains reaching speeds of . Most conceptions of the tunnel envision it between the United States and the United Kingdom ‒ or more specifically between New York City and London. The main barriers to constructing such a tunnel are cost first estimated $88–175 billion, now updated to $1–20 trillion, as well as limits of current materials science. Existing major tunnels, such as the Channel Tunnel, Seikan Tunnel and the Gotthard Base Tunnel, despite using less expensive technology than any yet proposed for the transatlantic tunnel, may struggle financially. Proposed tunnels Many variations of the concept exist, including a tube above the seabed, a tunnel beneath the ocean floor, or some combination of the two.

Vancouver Island Fixed Link
The Vancouver Island fixed link is any of various proposals to construct a fixed link by bridges, tunnels, and/or causeways across the Strait of Georgia, which connects Vancouver Island to the Lower Mainland of British Columbia. The strait has a minimum width of 19.4 km (12.05 mi) between Galiano Island and Tsawwassen Ferry Terminal. History The idea of constructing a fixed link has existed since the late 1800s. Public support for a fixed link resurfaced following a strike by employees of CP Steamships and the Black Ball Line in 1958 and the subsequent establishment of BC Ferries in 1960. Support again resurfaced after a controversial fare hikes in 1976. This led to a variety of studies to be published examining the feasibility of constructing a fixed link. A series of controversial fare hikes during the financial crisis of 2007–2008 again stoked calls for a fixed link. Feasibility Various studies were conducted throughout the 1980s and the 1990s to assess the feasibility of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
