Viaduct of Moresnet

The Viaduct of Moresnet is a railway bridge spanning the Geul Valley in Belgium, rising up to 52 meters above the landscape below. It consists of 22 bridge sections supported by solid stone bases and concrete foundations that carry trains across this deep valley.

The bridge was built starting in 1915 by German forces during World War I to move military supplies between Aachen and Antwerp. After the war, Belgium took control of the structure, and it became an essential link in the region's railway network.

The structure represents early 20th-century Belgian engineering methods with its 22 bridge sections supported by five stone pillars and sixteen concrete foundations.

The structure underwent major renovation between 2002 and 2004, which improved its condition and allowed faster train speeds. Visitors can best view this bridge from walking paths in the valley below, which offer views from underneath.

The bridge features a transition point between the Belgian 3 kV DC power system and the German 15 kV AC system, making it a unique intersection of two different rail networks. Specialized locomotives can handle this switch, allowing trains to cross the border without interruption.
