Project studies on tunnels

Tunnel construction projects for which official studies are available or which are in the preliminary planning phase, but whose construction decision is still pending or appears questionable.

Surname	Length in m	Country	location	function	comment
Cross-strait tunnel	150,000	CN TW	Formosa Street	railroad	Politically motivated by the People's Republic of China to tie up what it sees as a breakaway Taiwan , the economic viability, technical feasibility and, as a result, the serious will to implement this project must therefore be questioned.
Japan-Korea tunnel	128,000	JP KR	Korea Street	railroad	Realization only likely when goods traffic through North Korea is possible, appears in part to compete with the much shorter Sakhalin-Hokkaidō tunnel and Sakhalin tunnel as a permanent link between Japan and the Asian mainland.
Bohai tunnel	123,000	CN	Bohai Bay	railroad	Between Dalian and Yantai
Bering Strait Tunnel	104,000	RU US	Bering Strait	Railroad / pipelines	Continent connection between Asia and America, creates a land connection between all populated continents of the world without Australia / Oceania.
Talsinki tunnel	100,000	Fi it	Gulf of Finland	Railroad / pipelines	Connection of the two capitals Tallinn and Helsinki. This would form the metropolitan region of Talsinki.
Baltic Sea rail tunnel	97,000	SE DE	Baltic Sea	railroad	Rail tunnel between Malmö (Sweden) and Stralsund (Germany) to connect Oslo to Berlin. Economic viability due to the length of the tunnel and the future parallel connection through the Fehmarnbelt tunnel via Denmark is questionable.
Sakhalin Hokkaidō Tunnel	40,000	JP RU	La Pérouse Street	railroad	Fixed connection between Japan and the island of Sakhalin and thus to the Asian mainland via the Sakhalin tunnel.
Gibraltar tunnel	39,000	MA IT	Strait of Gibraltar	railroad	Continent connection between Europe and Africa.
Erzgebirge Tunnel	26,530	DE	Dresden - Prague	railroad	Study presented in January 2016
Barrandov tunnel	24,700	CZ	Prague - Beroun	railroad	deferred
Grimsel tunnel	22,000	CH	Innertkirchen - Oberwald	Railway + power supply
Pacheco pass tunnel	21,000	US	Diablo Range	railroad
Sachalin tunnel	12,400	RU	Tatar Sound	railroad	first planning: 1930s; first attempt: 1950–1953; last planning: 2000 possible start of construction: after 2020; creates conditions for a possible connection between the Asian mainland and Japan with the Sakhalin-Hokkaidō tunnel.
