Bridge across the Przemsza River

We initially proposed the concept of an arch bridge in skew with a directionally divided roadway to be replaced by a structure featuring two arch planes at the outer edges with no skew. However, this solution was rejected based on unfavourable opinions from authorities, despite its numerous advantages. As a result, the structural system of the deck was modified to include a central spine girder with cantilevered beams. The spine girder is suspended from a reinforced concrete arch, forming the Langer beam together. The spine beam is longitudinally prestressed, similar to the transverse beams carrying the directionally divided roadway and the deck slab between them. Each side of the bridge rests on a set of three bearings.
