and conducting basic research into natural and social conditions, and in 1998, in the "Hoyo Kaikyo Bridge Survey Report" it was concluded that the bridge would be technically feasible. The bridge proposed in the report uses a four-span suspension bridge with a central tower height of 376 m, central span length of 3,000 m, and bridge length of about 8,400 m as the main bridge, connecting the Toyo Strait with two bridges, the extension would be about 12.7 km. The total project cost is currently estimated to be about 1.3 trillion yen (US$12.1 billion).
The Hoyo Kaikyo Route Promotion Council conducted a survey comparing various crossing technologies (bridges, tunnels) and modes of transportation (automobiles, railways) in 1997, and "Transportation method comparison study report" was published. According to the report, in the case of bridges, road bridges are technically possible, but due to the long span, it is difficult to use them as railway bridges and combined bridges.[豊予海峡ルート輸送方式比較検討調査](_blank)

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.
Advantages compared to air travel would be increased speed and use of electricity instead of oil-based fuel.
The main barriers to constructing such a tunnel are cost, with estimates of between $88 billion and $175 billion, as well as the limits of current materials science.
