Viaduct across the Hrabynka Creek Valley

Completed in 2015

The viaduct of a total length of 330.0 m, which bridges the wide valley of the Hrabynka Creek, is formed by a continuous deck of six spans. The deck, 25.70 m wide and 3.35 m deep, consists of a single‑cell box girder with large overhangs supported by tubular struts. The girder is assembled from a steel beam of a trough cross-section and a composite concrete deck slab. The deck slab is made up of prefabricated elements (filigrees) and an additionally cast slab. The steel structure, together with the filigrees, was incrementally assembled behind the end abutment and launched into the projected position.
