Siebenbogenbrücke, Railway arch bridge in Fürth, Germany

The Siebenbogenbrücke is a 186.7 m long and 25.1 m wide railway bridge in Fürth, about 600 m west of the main station. Its seven arches each span 20.4 m and carry five railway tracks plus a footbridge roughly 10 m above the Rednitz valley; the river passes through the second arch from the right, seen from the south. A separate seven-arched concrete bridge for two S-Bahn tracks was added on the north side in 2010.

Construction began on 20 July 1862 under district engineer Reissinger, and the keystone was set on 11 September 1863. The bridge was widened in 1891/92 to carry four tracks, and in 1899/1900 a concrete bridge for a fifth track was added on the south side. German troops blew up one pier on 17 April 1945; the US Army built a temporary bridge that June and restored the Siebenbogenbrücke within two years. Between May 1969 and November 1970 it was widened by 2.4 metres and filled with concrete.

The name Siebenbogenbrücke simply counts the seven arches, each with a 20.4 m span. The bridge is still in rail use: five tracks and a footbridge, the Fronmüllersteg added in 1925, cross it about 10 m above the Rednitz valley. From the footpath the Rednitz can be seen passing through the second arch from the right, counting from the south.

The Siebenbogenbrücke lies about 600 metres west of Fürth Hauptbahnhof, where five tracks and a footbridge cross the Rednitz valley at roughly 10 metres above the river. The river passes, seen from the south, through the second arch from the right on the east side. The Fronmüllersteg, added on the south side in 1925, keeps the Westvorstadt connected to the centre during floods.

The Rednitz passes, seen from the south, through the second arch from the right, on the east side. The bridge was widened in 1969/70 by moving the overhead line masts off the deck into the Rednitz valley, and the track spacing grew from 3.5 to 4.0 m.
