The Ocean Tunnel is an underwater passage designed to facilitate transportation across bodies of water. It allows vehicles and trains to travel beneath the ocean, connecting different land masses while minimizing travel time. These tunnels are engineered to withstand high water pressure and are often constructed using advanced technology and materials. One of the most famous examples of an ocean tunnel is the Channel Tunnel, which links England and France beneath the English Channel. Ocean tunnels can also serve as vital infrastructure for submarine cables that carry internet and communication signals across oceans, enhancing global connectivity.
