Information

The entire bridge consists of three parts: approach structures on the left and right hand side of the river, made up of continuous prestressed concrete girders with the span of 45 to 75.5 m and reinforced concrete with the span of 35 to 38.5 m and a central steel structure with oblique tie-rods of 557.94 m length with the river span of 213.70 m.

§ The cross structure is formed by two main girders of the box cross-section with constan width and height, and they are inter-connected by orthotropic plate. The bridge deck of the orthotropic plate is sunk by 90 cm from the train girder upper belt, so that the channel is formed for the ballast in which the double railway track is laid. Service footways are situated outside the main girders. Under the footway- floor (which can be lifted) there are electric cable ducts. Heating pipes are positioned under the orthotropic plate and they are served by one pathway along the entire bridge. The pathways for the inspection cart with telescopic pulling of the lateral parts are positioned near the lower belt, on the interior side of the main girders.

§ The pylons are placed in the main girder centres above the columns and they exceed the main girders for 52.49 m. They are inter cross connected between the anchored places of the upper anti lower cluster of the steel ropes. The pylon column founding gyms on the reinlen-ced concrete caissons and of all other columns on the piles type HW", dia. 1,500 mm, length about 17 m.
