Stránovský viadukt, Railway arch bridge in Krnsko, Czech Republic.
The Stránovský viaduct is a railway arch bridge spanning 152 meters across the Strenická valley at a height of 27 meters. The structure uses reinforced concrete with three arches that each cover roughly 28 meters.
An earlier iron bridge from 1864 was completely rebuilt in 1924 when engineer Stanislav Bechyně designed the current reinforced concrete structure. The new design took roughly six months to complete and served as a modern crossing for rail traffic.
The structure marks an important development in Czech engineering methods and earned recognition as a cultural monument. Its curved concrete arches shape how the Strenická valley landscape appears to travelers passing through the region.
The viaduct carries daily train traffic on the Prague-Turnov railway line and is easily visible from the valley below. The best viewing angle comes from the valley path, where the arch structure shows most clearly.
This structure introduced parabolic concrete vaults in Czech bridge building and set new standards for railway infrastructure. The innovative techniques used here became a model for later construction projects across the region.
