Cable-stayed Bridge over the Odra River in Wroclaw, Poland

Abstract

<p>The largest bridge along the motorway ring road of Wroclaw is a cable-stayed structure over the Odra River near Redzin water stage of fall. The river flows there in its main bed, while inland navigation uses additional water channels. An island, where the pylon of the new bridge is situated, is located between the river and the channels. The bridge is 1742 m long and consists of a 610 m long southern flyover, a 612 m long cable-stayed main bridge with separate decks suspended to one 122 m high pylon and a 520 m long northern flyover. The superstructure of the main bridge consists of two box girders made of prestressed concrete, one for each carriageway of the highway. The height of the girder is 2.50 m, which is about 1/100th of the main span length. The decks are supported by 80 pairs of stay cables connected to the pylon made of reinforced concrete. The bridge with a deck area of approximately 65 000 m2 was constructed within 36 months.</p>
