Tunnels are long underground passageways that carry highways, railroads, and pipelines under mountains, seas, and rivers.The tunnel was drilled right through the mountains so cars and trucks could pass through. Tunnels can be built underground to carry people. Tunnels are also built to carry waste water away from the city.
The Tyne River Tunnel is indeed built partly under water. The lowest spot in the tunnel is 85 feet below the high water mark of the river.

A water way built to carry water for navigation or irrigation is a canal.
Jerusalem quite famously has no water. It sits on a hill overlooking no rivers or streams or seas or lakes of any kind. The only water which Jerusalem has access to is a fresh-water spring. This water was brought into the Old City by digging and underground passageway called "Hezekiah's Tunnel".

The oldest tunnel in the world is the Tunnel of Eupalinos, located on the Greek island of Samos. It was built in the 6th century BC to supply water to the ancient city of Pythagoreion.

The Holland Tunnel was built using the "cut-and-cover" method, where a trench was excavated on land, and then covered with a roof to create the tunnel. Construction began in 1920, and the underwater section was created by boring through the riverbed using a combination of compressed air and a circular tunnel boring machine. After the tunnel was completed, the trench was filled in with soil, and roadways were constructed on top. This innovative engineering allowed the tunnel to safely navigate under the Hudson River, linking New York City and New Jersey.
