At 1,860 feet long, or about one third of a mile, the Goltzsch Valley Bridge in the eastern German state of Saxony may seem like a minor player in the bridge world. But the length isn't what sets it apart; it's the material. At a time when most bridges were built with stone or metal, this one was built with bricks—20 million of them. It would be an odd (and costly) choice of material in most places, but in this area of Saxony, where there were several large clay deposits, it was an economical one. In fact, it's thanks to those same clay deposits that the second-largest brick bridge in the world, the Elster Valley Bridge, is also in Saxony; it's a quaint counterpart, made with only 12 million bricks.
