Construction required 35,000 cubic meters of masonry and 24,000 cubic meters of stone fill.
The bridge was built to accommodate the steep terrain of the Erzgebirge mountains, keeping the rail gradient manageable.
It replaced an earlier temporary wooden structure plan to ensure long-term durability for heavy steam locomotives.
The viaduct was designed by the engineer Claus Köpcke, who is also known for the Bastei Bridge in Saxon Switzerland.
The foundation stones are set directly into the local gneiss bedrock of the river valley.
The Hetzdorfer Viadukt is a historic railway bridge spanning the valley of the Flöha river between Hetzdorf and Falkenau. Originally constructed between 1866 and 1868, it served as a key engineering component of the Chemnitz-Freiberg railway line. The structure features 16 stone arches reaching a total length of 328 meters and a maximum height of 42 meters. It remains a functional railway bridge today, continuing to support active regional traffic. The viaduct is a recognized technical monument, reflecting mid-19th-century infrastructure development in Saxony. Visitors can access the area via walking paths that allow for a full view of the stone masonry. The surrounding valley provides a natural setting that contrasts with the industrial scale of the bridge. It represents an significant example of early steel-truss and masonry design transitions in German railway history.

Wear waterproof hiking boots as the paths in the Flöha valley can become muddy after rain.
Bring binoculars if you wish to inspect the stone masonry and decorative elements from the valley floor.
Check local railway apps for train schedules if you want to capture photos of active trains crossing the bridge.
Do not attempt to climb the bridge pillars or walk onto the rail tracks, as the line remains active.
Stay on marked trails to protect the local flora and avoid trespassing on the railway tracks.
