Brusio spiral viaduct

Nestled in the picturesque mountains of the Swiss Alps, the Brusio spiral viaduct is an architectural marvel that seamlessly blends engineering prowess with the natural beauty of its surroundings. This remarkable bridge, constructed in the early 20th century, is a testament to human ingenuity and the quest for efficient railway design.

The viaduct, located in the canton of Graubünden, is an essential component of the Bernina Railway, a UNESCO World Heritage site. It was specifically built to minimize the elevation difference for trains traveling between the towns of Tirano and St. Moritz, ensuring a smoother and safer transit through the steep terrain. The spiral design allows trains to ascend or descend without the need for steep gradients or additional mechanical assistance.

Standing as a circular monument of stone and steel, the Brusio spiral viaduct spans a length of 110 meters and rises to a height that allows a train to pass over itself, gaining the necessary altitude in a relatively short distance. The elegance of its construction is not just functional but also visually stunning, offering a unique spectacle for both rail passengers and onlookers. The viaduct's curvature and the panoramic views of the Swiss countryside it provides make it a popular spot for photographers and train enthusiasts alike.
