The Göltzschtalbrücke in Germany is the world's largest brick viaduct. Built between 1846 and 1851, it required over 26 million bricks and stands 78 meters tall, 574 meters long, and 23 meters wide at its base. It has 29 spans and was the first bridge to be calculated based on static data rather than previous architectural designs. Though an unusual building material, brick was chosen because of abundant local clay sources. Over 1,700 workers helped construct the bridge, with 31 deaths occurring during construction. It became the highest railway bridge in the world upon completion and remains the largest brick bridge ever built.
