Feasibility of Taiwan Province Strait Cross-Harbour Tunnel?

I hope that in the near future, the Taiwan Province Strait Railway Tunnel and Qiongzhou Strait Railway Tunnel will be completed, which will make the "natural barrier become a thoroughfare" and make daydreaming a reality.

Throughout the world, the English Channel railway tunnel connecting Britain and France is 50 kilometers long and 38 kilometers underwater. It was completed and opened to traffic in May 1994. The Qinghai-Han railway tunnel connecting Honshu and Hokkaido in Japan is 54 kilometers long and 23 kilometers underwater. Completed and opened to traffic in March 1988.

China Taiwan Province Strait Railway Tunnel connects the mainland and Taiwan Province Province, with a total length of125-150km. It is the longest and most difficult undersea tunnel in the world, and it will cost 400-500 billion RMB. What will it be like if it is built? It goes without saying that it is of great significance! Perhaps the most difficult thing is not technology and capital, but political reasons, and it depends on the convenient attitude of Taiwan Province Province. I think it is possible to reach an agreement through negotiation, and we should actively prepare technically and financially. As for where to build the channel, we can discuss it.

If the Qiongzhou Strait railway tunnel or bridge connecting Leizhou Peninsula and Hainan Island in China is built from the narrowest point, it is only 18km, with an average of 29.5km. Has it been included in the national plan? With the strengthening of national strength, today's daydream will become a reality. Isn't it? The South-to-North Water Transfer Project and the Three Gorges Dam are dreams come true!
