Bridge across the Hostovsky Creek Valley

Completed in 2011

The bridge has 17 spans of lengths 33 + 42 + 45 + 48 + 9 x 69 + 48 + 45 + 42 + 33 m. The deck consists of a single box girder with transverse overhangs which are supported by precast struts. The launched deck was erected progressively; at first the spine girder was cast in a formwork suspended on a special overhead gantry with ‘organic’ prestressing system (OPS) that eliminates deflection of the gantry; after that the struts were erected and the deck slab was cast.
