Bridge across the Stefanovsky Creek Valley, Motorway D1, Slovakia

Completed in 2015  

The bridge of the total length of 182.0 m has 4 spans of lengths from 37.3 m to 45.0 m. The deck of the width of 29.5 m 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 is cast in a formwork suspended on a special overhead gantry with ‘organic’ prestressing system (OPS) that eliminate deflection of the gantry; after that the struts are erected and the deck slab is cast.
