My walk beneath the River Elbe, Hamburg.

In these pictures, you can see one of the dual tunnels that go 12 meters under the Elbe River in Hamburg. The tunnel is used during weekdays for workers. There are car lifts on each end of the tunnel, and in one of the pictures here, you can see the entrance to one of them.

There are two tunnels, and lots of pedestrians use the tunnel too, but the pedestrians can use the tunnels anytime. Being Sunday, the tunnel was closed to cars, so I walked the tunnel with my friends Julie and Thorsten.

The walls of the tunnel are lined with beautiful ceramic tiles and it has such a turn of the century feeling, being built in only 4 years in 1904. I bet that people would be hard pressed to meet that sort of schedule now!
