The Föhringen railway bridge is located in the northern part of Munich between the Schwabing-Freimann district and the municipality of Unterföhring . On the railway bridge, the Munich Nordring crosses the Isar and the parallel Mittlere-Isar-Kanal .

history

The original bridge was built in 1907 as part of the freight route from Munich East via Freimann to Schwabing and was put into operation on June 5, 1909. The bridge was built using a stamped concrete structure and consisted of three arches with a span of around 30 meters each. It was single-track, but the pillar foundations were already designed for double-track expansion. Because of the canalization of the Isar, not only at this point, the river dug itself further and further. Although this was taken into account during construction, the process progressed faster than expected. To protect the bridge, a ground sill was built downstream to hold back the debris . In the course of the electrification of the route, the Deutsche Reichsbahn equipped the bridge with catenary masts in 1926.

For the double-track expansion of the Munich North Ring, the Deutsche Reichsbahn built a second bridge as a solid wall girder in steel from 1940 to 1941 on the pillar foundations already laid out on the north side of the old bridge. On April 30, 1945 the railway bridge and the adjacent road bridge ( Leinthalerbrücke ) were blown up. The steel girder of the northern line was lifted out of the Isar in May 1946 and repaired, so that a single-track operation was initially possible. As a replacement for the destroyed stamped concrete bridge on the southern track, a temporary screwed pioneer superstructure was erected.

From 1968 to 1969 the German Federal Railroad replaced the temporary bridge with a steel girder bridge . The new bridge consists of a 139.9 meter long welded continuous beam with a box girder and carries two tracks.

South of the Leinthalerbrücke, another road bridge, the Herzog-Heinrich-Brücke, has now been built on which the Föhringer Ring runs. The northern heating power station is located near the bridge .
