Longest underwater tunnels around the world
Have you ever wondered how people get from one place to another when there’s water in the way? Well, it’s all thanks to underwater tunnels! These incredible man-made structures help us travel conveniently beneath lakes, rivers, and even oceans. Here, we’ve curated a list of the five longest underwater tunnels ever created around the world, while also exploring the significant role they play in connecting us from one place to another, based on the data presented by several online media sources.
Great Belt Bridge Tunnel, Denmark
With a length of 8 kilometers (5 miles), the Great Belt Bridge is one of the longest underwater tunnels. It is a part of a large bridge and tunnel system in Denmark that connects the islands of Funen and Zealand. The tunnel goes under the Great Belt Strait, so cars can travel between the two islands without driving around the coast.

Eysturoyartunnilin, Faroe Islands
Eysturoyartunnilin, in the Faroe Islands, is another long underwater tunnel around the world, with a length of 11.2 kilometers (7 miles). This massive tunnel connects the islands of Eysturoy and Streymoy in the Faroe Islands, which are located in the North Atlantic Ocean. Before the tunnel, the only way to get between these two islands was by boat.

Tokyo Bay Aqua-Line, Japan
With a length of 15.1 kilometers (9.4 miles), the Tokyo Bay Aqua-Line is one of the longest tunnel and bridge systems that crosses Tokyo Bay. It connects the city of Kawasaki, which is near Tokyo, with Kisarazu in Chiba. The system includes a tunnel under the bay and a bridge over the water, making it a mix of both.

Qingdao Jiaozhou Bay Tunnel, China
The Qingdao Jiaozhou Bay Tunnel is a 9.47-kilometer (5.9 miles) tunnel under the water in China. It connects Qingdao City with the Huangdao district, making the drive much faster than going around the bay. This tunnel significantly helps in reducing traffic and travel time for drivers, and is known to be a major part of improving transportation in the Qingdao area.
