The Oder Bridge Frankfurt , a double-track railway bridge , is located near Frankfurt (Oder) or Świecko and spans the Oder at river kilometer 580.64. As part of the Frankfurt (Oder) –Posen railway line , it connects the Frankfurt (Oder) Oderbrücke and Kunowice stations . The state border between Germany and Poland runs in the middle of the Oder navigation channel , which corresponds to the DB route kilometer 4.135 on the structure. The bridge, originally built between 1868 and 1870, was rebuilt several times and replaced by a new one in 2008.
history
The railway bridge over the Oder was built by the Märkisch-Posener Eisenbahn-Gesellschaft from 1868 as part of the construction of the Frankfurt (Oder) –Posen railway line, and the line was put into operation on June 26, 1870. The 444 m long structure was a single-track iron truss bridge that was supported by ten pillars and two abutments . The substructures had already been laid out for a second track. The eleven superstructures had spans of 39.4 m. The bridge was equipped with an additional pillar on the upstream side and a truss arranged perpendicular to the bridge axis. This was equipped with lifting devices that enabled the sailing ships to put the mast or raise it.
In 1898, for strategic reasons , the bridge was supplemented by the superstructures for the track to Frankfurt for around 315,000 marks. Commissioning followed on April 13, 1899. Subsequently, the 30-year-old superstructures of the other track were reinforced due to increased train masses, which ended in early 1900.
Less than 30 years later, renovation measures were necessary again due to increased tensile loads. From 1926 on, the superstructures assembled in 1898 were reinforced and the older superstructures on the neighboring track were then replaced by new ones. Finally, in 1937 and 1938, the opening to shipping was widened. For this purpose, a river pillar in the waterway was removed, the neighboring pillars reinforced and a new 80 m wide superstructure was installed.
On February 19, 1945, German troops blew up the bridge for the first time, and on April 5, 1945 the remaining parts of the bridge, so that all the pillars were destroyed and the superstructures collapsed. As early as April 25th, Soviet military trains drove over a wooden makeshift bridge that had been built 30 m upstream by Red Army pioneers. The Soviet Union handled a large part of the transports with German reparations over the bridge, which was damaged by a flood in 1947.

The reconstruction of the Oder Bridge, now as a border bridge between Germany and Poland, began in 1946 on the old pillars and abutments. Most of the components of the old construction that had been preserved were used for the superstructures; the main opening was spanned with a temporary superstructure. In March 1947 the structure was put back into operation as a single track. Due to the extensive freight traffic, the complete repair of the structure followed by 1953 with the restoration of the superstructures of the second track and the installation of a new double-track, 80 m long superstructure over the Oderwasserstraße on November 1st and 2nd, 1952. In addition, in the west following the bridge was put into operation on May 23, 1954 for the freight traffic of the new border station Oderbrücke . In 1966, 45 freight trains with around 2000 wagons crossed the border bridge every day.
Electric train operation with 3000 volts direct current was started on the bridge by the Polish State Railways on May 28, 1988.
Due to the poor state of construction, the northern track was closed on December 9, 2005 and the maximum speed of the trains on the southern track was reduced to 50 km / h. In 2005, 24 pairs of trains ran over the bridge on working days. In 2008 the Oder Bridge was replaced by a new building as part of the Paris – Berlin – Warsaw line. For this purpose, the railway line was closed for two months from October 17 to December 13. The inauguration of the new bridge was on December 12, 2008. The investment costs of around 25 million euros were borne by the Federal Republic of Germany.

The bridge had six openings on the western and three on the eastern bank in the foreland area. The building system consisted of single-track single - span girders , parallel - chorded truss beams with an overhead track and spans of around 40 m. The Oderwasserstraße was spanned by an iron, parallel-belted stud truss with a carriageway below and a length of 80 m. The tracks were attached directly to the bridge structure without a ballast bed.

The new structure was moved 16 m in the direction of Poland. It has a continuous gravel bed. The approach bridges are prestressed concrete structures with the continuous beam as a structural system in the longitudinal direction. In cross-section, the superstructure consists of a single-cell prestressed reinforced concrete box girder with a construction height of 4 meters and inclined webs, prestressed in the longitudinal direction .
The western foreland bridge, with a total span of 206 m and a weight of 5220 tons, has four fields with spans of 44 m each, the field in front of the abutment spans 30 m. The eastern approach bridge, with a total span of 128 m and a weight of 3500 tons, has two openings with 44 m and one with 40 m length. Most of the approach bridges were completed in September 2008.
According to the original draft plan, the river bridge over the Oderwasserstraße was to be designed as a tied arch bridge with a weight of around 1600 t. Since their fatigue strength was not verifiable, planning was rescheduled from March 14, 2008 and a steel network arch bridge with 104 m span was manufactured, which was significantly lighter at 1100 t. In the first step, the old northern superstructures were dismantled. This was followed by the construction of new substructures and superstructures. There were difficulties and delays in the construction of the foundation for the pillars, which was up to eleven meters deep. Around 80 tons of scrap parts from the old bridge, which was blown up in 1945, had lodged in the construction or river bed and particularly hindered the ramming of the sheet piling . The foreign bodies had to be removed with the help of divers and heavy cranes. Finally, the southern superstructures were dismantled, the new prestressed concrete superstructures with masses of up to 6100 t, shifted sideways into the old route axis 9 m transversely and the steel river bridge with a mass of 1100 t, which was mounted in advance on the Polish bank with the help of pontoons and transport modules swam in.
