Bridge across the Dolianský Creek Valley, Motorway D1, Slovakia

Completed 2015

The bridge of the total length 414 m has 7 spans of lengths from 42.3 m to 65.0 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 is erected progressively; at first the spine girder is 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 are erected and the deck slab is cast.
