The bridge (or should it be called tunnel) goes under water to allow movement of ships.
In order for ships to pass, this bridge is half under the water.
You drive down in the water and then come out on the other side.
Truly a marvelous piece of engineering!
This bridge is between Sweden and Denmark.
The picture was taken from the Sweden side.
I hope that you could learn in your country with these project,
