Postcard from Germany!

Today I got a nice postcard from Germany! The postcard shows multiple views of the interesting  Hindenburgdamm, a causeway that joins the island of Sylt and mainland Germany. It is 11 kilometres long and and was opened in 1927. About 100 trains pass it everyday in order to get to the island. Half of them carry cars and other vehicles since there is no road joining the island and the mainland. The card is an official Postcrossing card, DE-2975332. Thanks Thomek!
