Railway bridge Hrob-Mlýny, Railway bridge in Mlýny, Czech Republic

The Hrob-Mlýny railway bridge is a steel structure spanning 130 meters across a valley in northern Bohemia. The bridge connects the village of Mlýny with surrounding areas and continues to carry train traffic across the regional rail line.

The bridge was designed by chief railway engineer Jan Bydžovský and built by the firm Schön & Wessely during construction of the Hrob–Dubí line in 1875–1876. Its original iron truss was dismantled and replaced in 1945. It was listed as a Czech cultural monument in 1964 under number 42327/5-2607.

The viaduct carries the Moldavian Mountain Railway over the Bouřlivec stream valley at Mlýny, a district of Hrob. It was listed as a cultural monument of the Czech Republic in 1964 under number 42327/5-2607. The line between Hrob and Dubí climbs more than 400 metres, which is why several bridges stand on this stretch.

The bridge remains in active use with regular train traffic passing through it several times daily on the regional line. Visitors can view the structure from both sides of the valley, with walking paths nearby offering different viewing angles.

The original iron truss was dismantled and replaced in 1945, so the steel spans seen today are not the 1870s work. The granite piers, 32 metres high, are original, and the bridge deck runs 33.9 metres above the Bouřlivec stream and 27.14 metres above the Hrob–Mikulov–Moldava road.
