Photo of the Day, Half Bridge Half Tunnel

This picture of the day is not directly related to chemical engineering stuff, but I admire and appreciate the engineering behind it. The bridge (or should it be called tunnel) goes under the water to allow movement of ships. In order to pass, this bridge is half under the water. You drive down in the water and then come out on the other side. Truly marvelous piece of engineering. This bridge is between Sweden and Denmark. This picture was taken from the Sweden side.
