The New Belgrade Railway Bridge ( Serbian Нови железнички мост, Novi železnički most ) is a railway bridge over the Save in Belgrade . It is part of the Belgrade railway junction and connects the Novi Beograd station with the new Belgrade Center station , commonly known as Prokop .
In the course of the 1928 m long double-track viaduct there is the Strombrücke, a steel, 558 m long cable-stayed bridge that crosses the Save with a span of 254 m. It was the first cable-stayed bridge for pure railway traffic in Yugoslavia .
Its six openings have pillar spacing of 54 + 85 + 50 + 254 + 50 + 65 m.
Its stiffening beam consists of two continuous single-cell hollow boxes with a constant construction height of 4.45 m and a width of 3.20 m. They are connected by an 8.10 m wide orthotropic plate , which is 70 cm lower than the cover plate of the box girders in order to have space for the ballast bed , which serves to reduce noise. Due to the weight of the ballast, a better ratio between the dead weight of the bridge and the high traffic loads is achieved, which contributes to the rigidity of the bridge.
The bridge is 16.5 m wide, including the two 1.0 m wide service routes attached to the outside.
The two steel pylons consist of vertical stems that are only connected and stiffened in the upper area by a traverse. They are 55 m high, measured from the upper edge of the box girders. They have single-cell rectangular cross-sections with a constant width of 1.90 m and a length that decreases from 3.10 m at the hollow boxes to 2.50 m at the tips.
The bridge was designed by Nikola Hajdin and Ljubomir Jeftović and built between 1975 and 1979. The steel construction was supplied by three Yugoslav companies, the ropes came from Switzerland and the assembly led Mostogradnja from Belgrade, which is also the other bridge section of a prestressed concrete - plate beam construction ran.
