Underwater bridges are built to cross over bodies of water too deep to allow passage beneath the water’s surface. These structures are typically constructed of reinforced concrete or steel, and they may be designed to support vehicular, pedestrian, or railway traffic. Underwater bridges can be found all over the world, crossing such waterways as rivers, lakes, and straits.
The first underwater bridge was the Brooklyn Bridge, which opened in 1883 and spans the East River between Manhattan and Brooklyn in New York City. At the time of its construction, the Brooklyn Bridge was the longest suspension bridge in the world, and it held that distinction for nearly 25 years. Today, the title of longest underwater bridge belongs to the Jiaozhou Bay Bridge in China, which is more than 26 miles (42 kilometers) long.

Is It Possible To Build A Bridge Across The Ocean?
Yes, it is possible to build a bridge across the ocean. However, there are many challenges that need to be considered when planning such a project.

How Do They Build A Tunnel Under Water?
There are thee primary ways to build an underwater tunnel: tunneling shields, tunnel boring machines, and immersed tubes.
Tunneling shields are large metal frames that are used to support the walls of the tunnel as it is being dug. The shield is moved forward a little bit at a time, and the workers dig out the earth behind it. This method was used to build the first underwater tunnel in 1825, beteen England and France.
Tunnel boring machines (TBMs) are massive machines that dig through the earth on their own. They have a rotating cutting head that grinds through the rock or soil, and they also have conveyor belts that carry the excavated material away. TBMs can dig through almost any type of terrain, and they were first used to build an underwater tunnel in Japan in 1965.
Immersed tubes are large sections of pipe that are floated into place and then sunk to the bottom of the river or ocean. They are usualy connected end-to-end to form a continuous tunnel. Immersed tubes are typically used for tunnels that carry vehicular traffic, such as cars or trains. The first immersed tube tunnel was built in England in 1843.
