The Nied railway bridge in Frankfurt am Main is the second oldest railway bridge still in operation in Germany . The arch bridge was built in 1838 and went into operation in 1839. The Taunus Railway crosses the Nidda on it . The bridge is located between Frankfurt Central Station and Frankfurt-Höchst Station in the Nied district .
construction
The 40 m long vaulted bridge consists of three arches, each 10 m wide . The curve radii of the reveals are each 8.40 m. Vaults, both river pillars and abutments are made of red sandstone blocks. Since the Nidda was not regulated until the 20th century and previously flooded regularly, the foundation of the bridge was particularly important: the pillars and abutments were anchored in the deeper soil layers with driven piles in order to transfer the load of the structure there.
history
Construction and opening
The bridge is based on a design by the engineer Paul Camille von Denis , under whose direction the Taunus Railway was built from 1837 to 1840. The bridge was opened on September 26, 1839 together with the first section of the route between the Free City of Frankfurt and Höchst , which at that time was still an independent city in the Duchy of Nassau . Initially, the line was only operated as a single track , but only expanded to double tracks in 1869, for which the width of the bridge was already designed when it was built.
Later construction work
In the course of the Nidda regulation between 1928 and 1932, the railway bridge was also secured and renovated. In 1931 and 1932 it was stabilized by additional anchors and cracks in the vault were filled with shotcrete. The foundations of the two pillars were reinforced with concrete jackets and the ice deflectors were raised up to the beginning of the reveal. The bridge was also given pedestrian walkways on the sides. This renovation work cost the Deutsche Reichsbahn 4,842.80 RM .
Adjacent to the Niddabrücke there was originally another bridge on the route, which served as a flood bridge. It was canceled in 1932 after the regulatory work was completed and the gap in the railway embankment closed.
The Niddabrücke was not damaged in either of the two world wars.
From November 27, 1978 to February 28, 1979 the bridge was renovated again. Additional anchors were set and cracks and joints were filled with spray mortar. For these construction projects invested by German Federal Railways more 30,728.80 DM .
present
The Taunus Railway still runs over the bridge. Today it is mainly used by regional traffic from three lines in the west of Frankfurt, including the Main-Lahn-Bahn to Limburg an der Lahn . Trains of the Königsteiner Bahn also operate there . The S-Bahn traffic is carried over the parallel line of the Main-Lahn-Bahn and its newer Niddabrücke, only a few meters away.
The high reliability of the stone vault construction is evident in the long service life of more than 170 years. To date, no changes have been made to the structure of the structure. The railway bridge is a cultural monument of the State of Hesse due to the Hessian Monument Protection Act . In addition, the structure is part of the Rhine-Main Industrial Culture Route .
Redevelopment
The long service life made a thorough renovation of the bridge necessary, which was completed in 2018.
Historical evaluation

In the history of local technology, the bridge was considered to be the oldest still-used railway bridge in Germany.
According to the latest study, which takes older literature into account, the railway bridge at Wurzen over today's B 6 on the Leipzig – Dresden railway line went into scheduled operation in September 1838 - one year before the Taunus Railway - and is still the oldest used railway bridge in Germany.
