Inundation bridge over the Lužnice in Stará Hlína, Technical monument in Stará Hlína, Czech Republic.

The Inundation Bridge over the Lužnice in Stará Hlína is a 119 m long stone bridge with twelve semicircular arches of 7.20 m span, built of quarry stone with parapet walls. The river flows under the third arch from the north. A granite plaque on the inner side of the eastern parapet bears the Latin inscription MDCCLXXXI DADIFICATUM SUB REGNANTE PRINCIPE JOSEPHO FR. SCHWARZENBERGI.

Jakub Krčín z Jelčan had a 902 m wooden bridge built in 1594 after the Rožmberk pond flooded the Moravian Road; a shorter second bridge followed in 1604. Floods repeatedly damaged them, and in 1741 a French garrison in Třeboň destroyed them to slow the Habsburg army. Prince Jan Schwarzenberg commissioned the present stone bridge in 1799, built by Josef Rosenauer, who later designed the Schwarzenberg and Vchynicko-Tetov canals. It carried long-distance traffic until 1988, when road I/34 was rerouted.

A granite plaque on the inner face of the eastern parapet carries the Latin inscription MDCCLXXXI DADIFICATUM SUB REGNANTE PRINCIPE JOSEPHO FR. SCHWARZENBERGI, recording construction in 1781 under Prince Joseph Franz Schwarzenberg. The bridge later appeared in the films Pan Vok odchází and Líbánky.

The bridge is 7 m wide and carries a local road with an asphalt surface, so it can be crossed on foot or by car. The Lužnice flows under the third arch from the north; the other eleven arches span the floodplain. A granite plaque with a Latin inscription is set into the inner face of the eastern parapet wall.

The bridge's twelve arches were designed so floodwater of the Lužnice passes beneath the spans instead of striking the structure. Its predecessor, a 902 m wooden bridge built by Jakub Krčín z Jelčan in 1594, was repeatedly damaged by floods and destroyed in 1741 by a French garrison from Třeboň. The stone bridge replaced that vulnerable crossing.
